Re: Supplemental Information Related to the Escanaba Paper Company (EPC) Best Available 

Retrofit Technology (BART) Recommendation and June 21, 2012 Meeting 

Dear Mr. Aburano: 

In preparation for our scheduled meeting on June 21, 2012, the NewPage Corporation Escanaba Paper 

Company (EPC) is providing U.S. EPA Region 5 with supplemental information regarding the Best 

Available Retrofit Technology (BART) determination for the No. 8 and No. 9 Boilers at the Escanaba, 

Michigan pulp and paper Mill. The supplemental information reflects the comments that U.S. EPA 

Region 5 provided to the Michigan Department of Environmental Quality (DEQ) on May 24, 2012. 

These comments include a recommendation to require the installation of low NOX burners on the two 

aforementioned boilers at the EPC Escanaba Mill. Based on a review of the U.S. EPA correspondence, 

EPC has supplemented previously supplied information concerning the operational characteristics of both 

boilers. The additional information reflects a description of how the boilers are actually operated, the 

feasibility of installing low NOX burners on either boiler, and a review of actual visibility impacts 

associated with NOX emissions from the two boilers. Based on the supplemental information and 

consistent with Michigan DEQ’s determination, EPC believes that no NOX controls are appropriate for 

both boilers. EPC greatly appreciates this opportunity to meet with U.S. EPA Region 5 to discuss the 

Mill’s BART determination in a timely fashion. 

The No. 9 Boiler at the EPC Mill is a Babcock and Wilcox (B&W) stoker grate boiler rated at 250,000 

pounds (lbs) of steam per hour and 360 million British Thermal Units (MMBtu) per hour (i.e., heat input). 

The permitted fuels for the No. 9 Boiler include woodwaste, natural gas, and paper cores. Particulate 

emissions are controlled with a multi-clone and a wet scrubber. EPC has identified the following issues 

related to U.S. EPA Region 5’s assessment of NOX emissions from the Boiler. 

 The No. 9 Boiler uses woodwaste generated by the Mill’s pulping operation to generate steam. 

To convert the No. 9 Boiler to 100% natural gas would “redefine” the basic operation of the 

boiler. 

 A switch of fuel from woodwaste to natural gas would increase the No. 9 Boiler’s carbon dioxide 

footprint as defined under other U.S. EPA regulatory programs. 

 There is no flue gas recirculation (FGR) installed on the No. 9 Boiler. 

 EPC is unaware of any low NOX burner technology that is applicable to the combustion of 

woodwaste. 

 The conversion of the No. 9 Boiler to natural gas would replace a zero cost fuel (woodwaste) with 

a higher cost fuel (natural gas). 
Mr. Douglas Aburano, U.S. EPA Region 5 

EPC BART Recommendation and Meeting 

Page 2 of 3 

G:\Client Files\NewPage Papers\Escanaba\C047 033 EPA BART Responses\June 2012 Response\Final Response\Region V Response.docx June 20, 2012 

 Visibility impacts from the No. 9 Boiler are no higher than 0.29 deciviews (dv) and the peak 98th

percentile is only 0.15 dv (visibility impacts reflect all emissions of all visibility impairing 

pollutants - VIPs). 

 A 40% NOX emission reduction would reduce the No. 9 Boiler visibility impacts by less than 0.1 

dv. 

The No. 8 Boiler is a Combustion Engineering boiler. It is rated at 450,000 lbs of steam per hour. The 

heat ratings for the No. 8 Boiler are nominally 594 MMBtu/hr for oil and 560 MMBtu/hr for natural gas. 

These two fuels are the only fuels that are permitted to be fired. FGR is used to reduce emissions and a 

NOX continuous emissions monitor (CEM) is operated. EPC has identified the following issues related to 

U.S. EPA Region 5’s assessment of NOX emissions from the No. 8 Boiler. 

 The No. 8 Boiler typically operates as a swing boiler, and only operates at higher peak loads 

when another steam boiler at the Mill is down for maintenance or repair, typically once or twice a 

year. A summary of the annual NOX emissions from the No. 8 Boiler is provided as Attachment 

A. As shown in this attachment, the NOX emissions for the past several years are significantly 

less than those for the 2004 and 2005 baseline period that was part of the initial BART analysis. 

 In 2009, EPC obtained a facility-specific price quote for installation of low NOX burners. The 

quote was prepared by Hamworthy Peabody (now a division of Coen) and identified a firm 

turnkey price quote of $797,900. EPC is in the process of updating the 2009 quote. A copy of 

the 2009 price quote is included as Attachment B. 

 Using U.S. EPA’s cost sheet assumptions, the 2009 Hamworthy Peabody pricing, a 40% NOX

emission reduction , and the 2005 annual reported NOX emissions results in a NOX costeffectiveness that is higher than that calculated by U.S. EPA. A copy of the control cost 

spreadsheet using the 2009 price quote is provided as Attachment C. EPC notes that preliminary 

conversations with the low NOX burner vendor have indicated that there will be a significant 

increase to the costs previously provided to EPC. 

 In the U.S. EPA cost sheet, EPC notes that credit is taken for the removal of the FGR system for 

NOX control. EPC believes that removing an existing NOX control inappropriately reduces the 

cost on a $ per ton of pollutant removed basis. There are many instances where U.S. EPA has 

combined NOX control measures. EPC is unaware of any instance where U.S. EPA has 

advocated removal of a control measure. 

 While a 40% NOX removal efficiency is used to develop the cost effectiveness numbers for the 

No. 8 Boiler, it may not be practical to achieve this removal efficiency given the already low NOX

emission rate. As shown in Attachment A, the annual average NOX emission factors range from 

0.261 to 0.157 lbs of NOX/MMBtu. Consequently, the cost effectiveness numbers can vary 

significantly. Attachment D provides a summary of the potential post-control NOX emissions and 

a range of cost effectiveness numbers for the 2004 thru 2011 period. 

 Visibility impacts from the No. 8 Boiler were overstated as part of the initial BART submittal. A 

review of the actual short-term and annual operating modes for the No. 8 Boiler show that the 

boiler has emitted at the NOX emission rate used in the visibility modeling analysis exactly 3 days 

over the April 2004 to December 2011 period.

G:\Client Files\NewPage Papers\Escanaba\C047 033 EPA BART Responses\June 2012 Response\Final Response\Region V Response.docx June 20, 2012 

 EPC believes that the application of any NOX control on the No. 8 Boiler will result in minor 

emission reductions and will similarly result in insignificant visibility improvement. 

For the reasons identified above and considering the supplemental information that is attached to this 

letter, EPC believes that the Michigan DEQ BART determination for the Mill is appropriate. EPC looks 

forward to meeting with U.S. EPA Region 5 and the Michigan DEQ to discuss this matter. Prior to the 

meeting, if there are any questions regarding the information presented in this letter, please contact me at

I) Introduction:

Hamworthy Peabody Combustion (HPC) is pleased to submit our firm priced turnkey proposal 

for the design, engineering, supply, installation and commissioning of combustion equipment 

and services as they relate to the Boiler 8 burner retrofit project for one (1) existing C-E VU-60 

boiler rated at 450,000 lb/h steam output at Coated Paper in Escanaba, Michigan. 

This proposal covers the supply, installation, and commissioning of one (1) multi-burner natural 

gas and oil system; consisting of burners and local valve trains. 

The existing forced draft boiler has 4 (four) burners mounted in one windbox; the bottom two 

burners are dual fuel natural gas and number 6 fuel oil, the top two burners are natural gas only. 

The existing configuration is not in compliance with the required NOx emissions permits for the 

boiler, limiting the overall use of the system. 

The purpose of this retrofit is to reduce the NOx emissions on No.6 fuel oil and natural gas, as 

well as eliminate mechanical issues with the existing burner air slides and significantly reduce 

the manpower required to fire oil. The proposed upgrade includes replacement of local burner 

valve trains (the header trains will be reused) to comply with current NFPA 85 standards and 

insurance requirements. The HPC replacement dual fuel burners will fire both natural gas and 

No.6 fuel oil. 

3⁄4 Due to recent advances in our burner design, we are able to meet your NOx emissions 

requirements of 0.2lb/MMBtu on natural gas and 0.4lb/MMBtu on No.6 fuel oil without 

having to alter the existing FGR arrangement. An additional FGR fan is not required. 

3⁄4 Hamworthy Peabody has incorporated a fully automatic oil firing system, which will allow 

starting, stopping, and purging the oil system from the control room without local operator 

assistance.

Based upon our site visit and subsequent discussions, our scope of supply detailed herein will 

include: 

• Four (4) New Low NOx MSC2 burners consisting of: 

3⁄4 Single pneumatic cylinder operated air slide 

3⁄4 Q-jetTM Low NOx center-fired natural gas burner 

3⁄4 Pneumatically retracting BC Oil Unit with Spirojet Low NOx No.6 Fuel oil tips 

3⁄4 Reliable HPC FPM Natural Gas ignitor 

3⁄4 New Plastic refractory burner throat 

• SmartFlowTM Windbox and Ducting Model Study to ensure even airflow to the burners 

resulting in efficient and low emissions combustion (including required baffling) 

• Local burner natural gas, ignitor, no.6 fuel oil, and atomizing steam valve trains and 

components. 

• New main oil flow meter 

• New air flow measuring piezometer and transmitter 

• Revise existing Combustion Control and Burner Management System logic. 

Our intention is to reuse as much equipment as possible without adversely affecting the system 

reliability. The reused components include: 

• Natural gas, ignitor, No.6 fuel oil, and atomizing steam header valve trains, including 

valves and piping; the fuel oil flow meter will be replaced 

• The windbox and ducting with modifications 

• The FD fan and FGR system 

• The Combustion Control and Burner Management Systems (modified by HPC) 

• Boiler devices, including steam pressure switches, steam pressure transmitters, etc. 

In a Hamworthy Peabody turnkey solution there are no contractual layers between the 

customer, the equipment supplier, and the installer; Hamworthy Peabody has full “single point” 

responsibility for the total project implementation. 

As part of our total Turnkey Solution Hamworthy Peabody will supply all labor, supervision, 

tools, equipment, consumables, safety equipment, pipe, pipe fittings, tubing, tube fittings, pipe 

hangers, supports, structural steel, wire, conduit, cable tray, junction and other miscellaneous 

materials and support services required to complete the installation of the mechanical and 

electrical equipment for this project. 

Hamworthy Peabody Combustion’s supply includes a site project manager whose responsibility 

is to ensure proper installation of all equipment by the contractors and to maintain set project 

schedule. Following a complete system checkout, the HPC site engineer will commission the 

system, turning over a fully operational system at the conclusion of the project.

II) Project Overview:

A. Combustion Equipment 

Following our site visit, a detailed review of the original boiler drawings, and a review of 

the project goals, we have determined that our MSC2

 Low NOx Dual Fuel burner fit with 

a Q-jetTM center fired gas burner is best suited for this application. 

MSC2

 Low NOx Burner:

The basis for the MSC2 TM burner’s operation is Multi-Stage Combustion (MSC). The 

staged Q-jetTM design introduces fuel into primary and secondary air streams. The 

primary stream allows for our new STABLEflameTM technology, ensuring an ultra-strong 

root flame for stability. The secondary zone stages the flame to mitigate thermal NOx 

production. 

MSC2

 Sample Burner Pictures 

The air entry to gas and swirler were strategically designed to optimize combustion 

staging, balancing minimal flame temperature with precision flame shaping. Low CO 

and particulate performance, while maintaining low NOx, has been attained. The MSC2

is a highly reliable, efficient, low excess air/low NOx burner that can meet the emission 

reduction needs for today and tomorrow. 

Side View of the proposed burner arrangement depicted. 

Q-jetTM Center Fired Burner:

The Q-jetTM center fired natural gas burner is positioned down the center of the burner. 

Through gas placement geometry, it achieves fuel staging necessary for Low NOx 

combustion.

70 Shelton Technology Center, Shelton, Connecticut, 06484 USA Tel.: (203) 922-1199 Fax: (203) 922-9413

No.6 Fuel Oil Unit:

We have included one pneumatically retracted Hamworthy Peabody BCT steam 

atomized oil unit per burner. The unit is of a twin tube (oil, steam) inside mix design. 

Proper atomization is assured by sheering action and mixing of the steam and oil in the 

proven Hamworthy Peabody SPIROjetTM tip and plug. The tip and plug are easily 

removed for cleaning and maintenance when required. The unit operates on a constant 

differential pressure system which supplies the atomizing media to the unit at a pressure 

which is a nominal 20 psig greater than that which the oil is supplied. This pressure 

differential is maintained throughout the load range, thus minimizing atomizing steam 

consumption and maximizing turndown. 

The oil unit is supplied complete with burner couplings for easy removal, manual valves 

for steam and oil as well as metallic flexible hoses for connection to the oil and steam 

supply points. The Low NOx SPIROjetTM tip and plug included with this equipment are 

custom designed based on the specific fuel flow rates, pressures, and furnace 

dimensions.

FPM Ignitor:

The Hamworthy Peabody FPM gas-electric ignitor has proven to be extremely stable 

and reliable in register and parallel flow burners. Its unique pilot and nozzle assembly, 

with dual perforated ends assures stable operation even in varying air flow streams. The 

standard ignitor comes complete with 10,000 VAC ignition transformer mounted in a 

NEMA-4 enclosure, electrical harness and gas hose. 

FPM Natural Gas Ignitor 

B. Airflow Model Study

Using our in-house, HPC SmartFlowTM Technology, Hamworthy Peabody Combustion 

will design and build a customized, Plexiglas, physical air flow model (approximately 

12:1 scale) of the burner/windbox and duct assembly. An air flow analysis provides 

invaluable information when designing an internal baffle system to optimize the air flow 

thru the burner. This allows for maximum emission control and boiler efficiency, and 

minimizes system draft losses.

Hamworthy Peabody Combustion, Inc. 

70 Shelton Technology Center, Shelton, Connecticut, 06484 USA Tel.: (203) 922-1199 Fax: (203) 922-9413

The goal of the physical airflow modeling is for the modeler to provide a set of baffle and 

turning vane drawings designed to provide an even airflow distribution to the windbox 

and burners. Baffles shall be added only as required to the model to balance the airflow 

throughout the inlet ducting to burner. Based on the results of the model, a drawing 

showing recommended baffles for the actual windbox shall be provided such that the 

result is a matched ducting / burner configuration that will assure balanced air flow and 

optimum burner performance. 

At the completion of the analysis, the results shall be discussed and documented in a 

written report. The report will include a brief description of the physical model, the model 

assumptions, and the boundary conditions. The results shall cover the “as-is” conditions 

of the ductwork, as well as the results of adding the recommended flow distribution 

devices. 

a. One (1) copy of the final report, as well as one (1) electronic copy shall be 

provided. This shall include all photographs, drawings, graphs, data 

tables, and conclusions. 

b. Complete set of drawings showing the locations of baffles and turning 

vanes required to ensure proper air flow distribution 

C. Fuel Delivery System

The existing local burner valve trains will be replaced for all fuels and atomizing steam. 

The existing main gas burner valve trains do not comply with NFPA 85 vent valve sizing; 

the existing oil and steam burner trains are not sufficiently automated to permit control 

room start and stop. The new valve train components will be FM approved and are 

designed to comply with ASME B31.1 and NFPA 85 2007 Edition. All of the existing 

header valve trains will be reused, as is. 

Main Natural Gas:

We have included for reusing the main gas header valve train piping and components, 

including (but not limited to) the flow control valve, safety shut off valve, flow meter, and 

vent valve. The main gas ring header that supplied gas to the existing burners will also 

be reused. 

The local main natural gas trains will be replaced with new 4” Maxon safety shutoff and 

2” Maxon vent valves. The new vent valve will tie into the existing vent piping. A new 

flexible gas hose will also be supplied for each burner. 

The gas piping proposed has flanged, socket welded, and butt welded connections, 

threaded fittings will be minimized in accordance with B31.1. The new valve train 

components will be factory designed and field installed and wired in accordance with 

HPC drawings.

70 Shelton Technology Center, Shelton, Connecticut, 06484 USA Tel.: (203) 922-1199 Fax: (203) 922-9413

Ignitor Natural Gas:

Hamworthy Peabody Combustion proposes replacing the existing local ignitor valve 

trains to support our new FPM ignitor. The existing header ignitor train will be reused. 

The trains will be ASME B31.1 construction, FNPT connections, schedule 80 seamless 

piping. 

No.6 Fuel Oil Piping:

The existing fuel oil header system will be reused, with the exception of the fuel oil flow 

meter, which HPC will replace with a new accurate dP type flow meter. Hamworthy 

Peabody Combustion intends on replacing the entire local valve train with updated 

components designed for use with No.6 fuel oil. In place of the existing Maxon shutoff 

valves, we propose the use of a 1” ITT Skotch valve that incorporates the oil, steam, and 

automatic purge valves in very reliable and rugged unit. The valve train components will 

be field installed in accordance with HPC drawings. The trains will be ASME B31.1 

construction, CL300 flanged connections, 3000# fittings, schedule 80 seamless piping. 

ITT Skotch Trifecta Oil, Atomizing steam, and Purge Valve 

Atomizing Steam:

Hamworthy Peabody will reuse the existing atomizing steam header and differential 

pressure control valve. The piping from the header to the burner front will be modified. 

Specifically, the vertical riser on the left side of the boiler will be removed. A new riser 

on the right side of the boiler will be added, following the path of the oil system vertical 

riser. The Trifecta valve will attach to the steam line and will incorporate automatic oil 

sprayer purging upon normal burner shutdown. A new flexible hose will connect the 

steam line to the burner inlet. The valve train components will be field installed in 

accordance with HPC arrangement drawings. The trains will be ASME B31.1 

construction, socket welded or CL300 connections, 3000# fittings, schedule 80 seamless 

piping.

D. Burner Management System 

We propose to modify the existing Burner Management System to accommodate the 

new burner and valve train equipment. HPC will supply Boolean Logic diagrams and a 

brief written narrative for NewPage to implement into their existing BMS. 

HPC will confirm proper tagging of existing wires when removed during the installation. 

We will re-terminate all wiring of the Natural Gas valve train components at existing 

locations. 

HPC will wire the new oil/atomizing steam safety shut-off valves. They will require seven 

(7) conductors and two (2) spares. The new wires will run where the existing wiring is 

through cable tray to the existing BMS I/O control room location. 

There will be two (2) additional solenoids and three (3) additional switches all generally 

located within 2’ at the center line of each burner. These will be shop wired to a single 

junction box located in this area. HPC will pull seven (7) and two (2) spare conductors to 

the existing BMS I/O control cabinets as described above. 

 

All Digital 120VAC control wiring shall be red #14 AWG THHN 600V rated with wire 

markers on both ends. 

E. Combustion Control System (CCS)

For the Combustion Control System (CCS), HPC will make the appropriate adjustments 

to ensure that the system functions at its most efficient configuration. HPC will supply 

SAMA Logic diagrams and a brief written narrative for New Page to implement into their 

existing Foxboro DCS. 

HPC will also install a new piezometer airflow transmitter along with the 4-20 mA wiring 

that goes along with it into the existing Foxboro DCS. The piezometer will be located 

upstream of the fan and FGR connection near the ducting inlet.

Hamworthy Peabody will supply all labor, supervision, tools, equipment, consumables, 

safety equipment, pipe, pipe fittings, tubing, tube fittings, pipe hangers, supports, 

structural steel, wire, conduit, cable tray, junction and other misc. materials and support 

services required to complete the installation of the mechanical and electrical equipment 

for this project. 

Hamworthy Peabody Combustion will supply a site project manager whose responsibility 

is to ensure proper installation of all equipment by the contractors and to maintain set 

project schedule. 

Specific demolition and installation activities are detailed in this proposal. 

G. Check Out and Commissioning:

Hamworthy Peabody Combustion will use one of our experienced service engineers to 

perform a full equipment and system checkout prior to commissioning. This will ensure 

a smooth start up. 

A Hamworthy Peabody Combustion service engineer will then commission our

7. Natural Gas Ignitor: The header piping for the natural gas ignitors will be reused. 

The local ignitor trains will be replaced with new solenoid valves, etc. The new 

trains will be located close to where the existing trains are positioned. 

8. The No.6 Fuel Oil System: The main oil header is going to be reused, with the 

exception of the oil flow meter which will be replaced with a new unit, flanged end 

connections. The piping local to each burner will be removed. The riser headers 

from the horizontal header on the first floor will be reused. Coming off each riser 

will be manual valve and an ITT Skotch Trifecta oil shutoff valve for each burner. 

One connection on the valve is the oil and the other is the steam. 

The valves will be located on the right side of each burner, where the existing oil 

riser tap-off exists. This valve incorporates an auto purge feature, eliminating 

most of the boiler front piping that currently exists. The recirculation line will be 

reused, and will tie-in upstream of the Skotch valve. All oil piping will be painted 

in accordance with NewPage specifications and insulated.

Summary: 

ASTM D3228 

This method covers the determination of nitrogen in fuel oils when present in the 

concentration from 0.015 to 2.0% mass. 

Note: This method may not be applicable to certain materials containing N-O or 

N-N linkage. 

Method - Modified Kjeldhal Method 

ASTM D4629 

This method covers the determination of trace total nitrogen naturally found in 

liquid hydrocarbons boiling in the range of 50 to 400 °C, with viscosities between 

0.2 and 10 cSt (mm2/s) at room temperature. This method is applicable to 

distillates and oils containing 0.00003% to 0.01% nitrogen by mass. 

Method - Syringe Inlet Oxidative Combustion & Chemiluminescence 

ASTM D5762 

This method covers the determination of nitrogen in liquid hydrocarbons in the 

range from 0.004 to 1% nitrogen by mass. For light hydrocarbons containing less 

than 0.1% nitrogen, Test Method D4629 is more appropriate. 

Method - Boat-Inlet Chemiluminescence 

Note: The accuracy of the methods is given as + % N2. Therefore if the 

analysis of the oil gives a reading of 0.3% and the accuracy is 

quoted + 0.17% N2, this means the actual level of the Nitrogen is 

between 0.13 - 0.47%

Exceptions & Clarifications:

- Hamworthy Peabody reserves the right to inspect the boiler / furnace during the proposal 

and/or contract stages to verify furnace conditions. 

- As specified, and due to the unknown extent of asbestos, lead based paint and silica 

containing areas; we have excluded abatement of these materials from our scope as well as 

any scheduling or cost impacts. 

- Unless otherwise specified the equipment sizing, performance and pricing is based on the 

fuel analysis stated in the Technical Specification of this proposal. Any variations in actual 

fuel analysis may alter performance and emissions. 

- HPC has offered a prediction on no flame impingement as defined by ABMA: 

 

 Per the American Boiler Manufacturers Association (ABMA): 

Flame impingement is defined as the condition which exists when the flame 

resulting from the combustion of the fuel comes into contact with any interior 

surface of the furnace in such a way as to result in localized incomplete 

combustion of the fuel and such condition manifests itself in the formation of hard 

carbonaceous deposits at the contact location. Flame impingement is a condition 

of firing a fuel which may cause failure and/or excessive maintenance of 

combustion chamber wall surfaces. 

If a particular flame length is required as a guarantee, then HPC will require that the 

furnace needs to be completely/100% air tight with a distribution grid for a CO Travers 

where the boundaries of the flame will be considered to be with values above 2,500 ppm 

CO. 

- We have not had an opportunity to inspect the inside of the boiler / furnace. Thus, our 

quotation is based on the premise that all existing boiler design criteria reflects the actual 

operating conditions prior to burner modification and upon request Purchaser can document 

such operating conditions. 

- HPC has not included for any seismic loading or calculations in our offering. 

- HPC has not included for any PE stamping of our drawings submittals.

VII) Company Profile and Technical Capability:

A. Company Profile: 

Hamworthy Peabody Combustion History:

Hamworthy Peabody Combustion was founded by Ernest Peabody in 1920. Prior to forming 

Hamworthy Peabody Combustion, Ernest took a position with Babcock & Wilcox, where he was 

assigned to investigate methods of burning fuel oil. Peabody showed his early productive talents by 

inventing a revolutionary oil furnace and developing mechanical atomizers badly needed by the U.S. 

Navy. 

Peabody's pioneering spirit was combined with an entrepreneurial instinct. In 1920, he organized the 

Peabody Engineering Corporation, beginning more than four decades of personal leadership in the 

manufacture of unique combustion equipment for industry. 

The new company's initial mission was to develop a wide-range 

mechanical atomizing burner based on principles discovered by 

Commander Joseph Fisher (USN) to atomize oil for diesel engines. 

The famous Peabody-Fisher burner, using a recirculating oil 

atomizing tip, was patented in 1921. This development allowed 

individual mechanical atomizing oil burners to operate over a wide 

capacity range for the first time. 

The company rapidly became a supplier of large burners for boiler 

applications, an activity that formed the base for Peabody's growth 

up to the present. 

The early 1920's were a time of innovation with new patents, products, and installations. A versatile 

double-port register burner was patented, equipment for scrubbing flue gases was introduced, and 

large installations were completed ranging from steamships (SS Leviathan) to power stations 

(Cumberland Power & Light) to commercial (R.H. Macy & Co.) and industrial facilities (Johns-Manville 

Co.). 

Still growing through the great depression and during the years leading up to World War II, additional 

burner patents were obtained and dozens of burner designs were introduced, including the well known 

Type M multifuel burner that could fire gas and oil alone or in combination. An early version of this 

outstanding burner is part of the Smithsonian permanent collection. 

During WW II, Peabody Engineering provided burners and associated combustion equipment for the 

thousands of cargo ships ferrying material to battlefronts around the globe. Wartime developments 

included the introduction of Peabody Type A and Type H gas and oil burners and an emphasis on 

"constant differential" wide-range oil burning systems. 

In the high-growth, postwar period, and through the early 1950's Peabody Engineering introduced 

many additional products including ignition equipment, remote burner controls, burner systems 

designed for use with package boilers, kiln burners, and a line of patented gas/oil and solid fuel 

burners. Other products at the time included gas scrubbers, coolers, and absorbers; refinery burners; 

flame failure detection systems; and direct-fired air heaters.

70 Shelton Technology Center, Shelton, Connecticut, 06484 USA Tel.: (203) 922-1199 Fax: (203) 922-9413

A few of the hundreds of important installations made during the 1950's included West Point Military 

Academy, Brooklyn Union Gas Company, Gimbel Brothers, and Eberhard Faber Pencil Company. 

Peabody Engineering was a New York City entity until it transferred all operations to Stamford, 

Connecticut in 1969. It's unique contributions to combustion technology attracted international 

attention. As far back as 1928, a subsidiary was formed in England, where Peabody carried on an 

aggressive research and development effort. 

A Canadian subsidiary, Peabody Engineering Canada, Ltd., established in Toronto in 1959, brings 

Peabody products to that important sector of the world. In 1984, Peabody Engineering formed 

Ingeneria Peabody S.A. de C.V. in partnership with Groupo Industrial AXIS, and established a 

dominant position in the Mexican marketplace for combustion equipment. 

This international presence has seen the installation of Peabody equipment around the world – to the 

Middle East and Far East, to Central and South America, Africa, Australia, and Japan. 

A major development in the 1970's was the development of the Air Pressure Recovery (APRTM) lowexcess air burner which provides electric utilities and industrial power plants with a high efficiency, 

multi-fuel burner that reduces fuel costs and stack emissions. Initial large utility installations at Florida 

Power, Puerto Rico Electric Power Authority, and Consolidated Edison proved the value of this 

revolutionary burner. 

By careful control of air flow, the APR burner provides highly efficient mixing of fuel and air resulting in 

outstanding performance. More than 1000 APR burners are installed in nearly 100 locations worldwide, 

making it the burner of choice for high-efficiency/low emission applications. 

The 1980's brought unprecedented progress in the continuing growth of Peabody Engineering as a 

leading manufacturer of combustion equipment. During this period, clean-burning Peabody low-excess 

air burners continued to be installed in record numbers. 

Peabody burner management, flame detection, and ignition systems set the standard for reliability. 

And Peabody equipment for the process industries remained an important part of an expanding product 

line. 

In the first of several partnerships, Peabody Engineering began significant restructuring when it joined 

Hercules Galion in 1969 forming Peabody Galion Corporation – later to become Peabody International 

Corporation. In 1985 Peabody 

International and Pullman Corporation merged creating Pullman-Peabody Company to provide 

transportation, energy, and process related products. 

Since 1992, Peabody Engineering has been a cornerstone of the Hamworthy Group of combustion 

companies that includes Hamworthy Combustion Systems, Airoil-Flaregas, and Peabody Engineering 

Ltd., all of the United Kingdom. This association places Peabody Engineering in a group of combustion 

companies with worldwide activities and provides access to European technologies and products. The 

Group is supported by one of the world's largest oil and gas firing test facilities. 

A major effort beginning in the 1980's and continuing today is the development of a technically 

advanced burner that reduces NOx formation, has low CO emissions, produces less particulates, and 

operates at fuel efficient low-excess air levels.

The resulting Peabody-Hamworthy DFL / MSC2 low NOx burners provide these benefits without the use 

of costly external porting, flue gas recirculation, or additional emission control equipment. It sets the 

standard for low NOx operation and continues Peabody's position of combustion leadership. Over all 

its years of operation, Peabody Engineering has had a deep involvement with American industry. 

Peabody equipment, for example, is installed at more than 32 different plants representing 22 

companies in the pulp and paper industry alone. 

The company also continues a long-standing tradition of supporting the steam generation industry. 

Ernest Peabody helped establish the Industrial Oil Burning Equipment Association in the early 1930's to 

protect large oil burning facilities from unfair government standards. Peabody Engineering, as a 

member of the American Boiler Manufacturers Association, continues to be attentive to association 

interests and goals. 

An important part of the company's task today is the investigation of new markets to supplement the 

maturing power industry. Completely new product lines are being developed by the Hamworthy Group 

while Peabody continues to define its position in specialized combustion equipment such as burners 

designed to augment heat input for cogeneration and fluidized bed combustor systems. 

In August of 2004 Peabody Engineering Corporation as part of the Hamworthy Combustion Group 

changed its name to Hamworthy Peabody Combustion, Inc. 

Hamworthy Peabody Combustion will continue to build on its 80+ years of excellence with efficient, 

reliable combustion equipment designed to improve existing installations, meet the requirements of 

evolving applications, and serve entirely new areas yet to be recognized.
