NOx RACT Study 

Gentlemen: 

November 14, 2008 

Mr. David Hearne 

Ohio EPA- Agency 13 (Cuyahoga) 

Cleveland Division of Air Quality 

1300 E. 9th Street 

Cleveland, OH 44114 

In accordance with the requirements contained in OAC 3745-110, the Northeast 

Ohio Regional Sewer District conducted a NOx RACT Study for two mid-sized package 

boilers (sources B002 and B003) located at its Southerly Wastewater Treatment Center. 

The study was conducted to determine whether or not there are any technically 

feasible and cost-effective techniques for reducing NOx emissions from the two package 

boilers to meet the new NOx RACT limit of 0.10 lbs (NOx)/mmBTU input. 

The only technically feasible technique was the replacement of the existing low 

NOx burners with new ultra low NOx burners. Quotations were obtained from three""' 

vendorsa~d the ann~~raveragec~st:effectiveness of installing new ultra low NOx 

burners has been estimated to be $51,744/ton ofNOx reduced. The cost-effectiveness 

ranges from a low of $39,831/ton ofNOx reduced to a high of$72,898/ton ofNOx 

reduced. 

As a result, the NEORSD respectfully requests that the existing NOx limit for 

! sources B002 and B003 of0.15 lbs/mmBTU be retained. '" 

It should also be noted that the Southerly WWTC has four multiple hearth 

incinerators in which biosolids (sewage sludge) is burned. The NEORSD is getting ready 

to replace the multiple hearth incinerators with new fluidized bed incinerators. 

3900 Euclid Avenue 1 Cleveland, OH 441151 P: (216) 881·6600 1 F: (216) 881·7703 
In February 2008, Ohio EPA personnel informed the City of Cleveland Division 

of Air Quality (CDAQ) that Southerly's new fluidized bed incinerators would be subject 

to NOx RACT requirements. In a letter dated February 25, 2008 (copy attached), we 

explained the reasons why the new fluidized bed incinerators should not be subject to 

NOx RACT requirements. 

On AprillO, 2008, Sarah Rehner (CDAQ) informed me that both Ohio EPA and 

CDAQ personnel agree that Southerly's new fluidized bed incinerators are not subject to 

NOx RACT requirements, due to the reasons contained in the attached letter. In addition, 

Ohio EPA and CDAQ personnel also agreed that Southerly's existing multiple hearth 

incinerators are not subject to NOx RACT requirements since they are being replaced 

with new fluidized bed incinerators. 

Please do not hesitate to contact me at 216-881-6600 ext. 6405 if you have any 

questions or require additional information.

When boiler No. B003 was placed into service in the early 1990s, it was 

equipped with a low NOx burner to meet a permit limit of 0.15 lbs/mmBTU input. 

At the same time a new low NOx burner was installed in boiler No. B002. 

Current discussions with a number of burner manufacturers indicated that 

burner technology has progressed to a point that we can meet the 0.1 lbs/mmBTU 

input limit by retrofitting the existing boilers with new ultra low NOx burners. 

Below are calculations to determine the NOx reduction from both boilers in 

the event that new ultra low NOx burners are installed in B002 and B003.

Combustion control techniques reduce the amount ofNOx emission by 

limiting the amount ofNOx formation during the combustion process. This is 

typically accomplished by lowering flame temperatures. Combustion control 

techniques are generally more economical than post combustion methods and have 

been used to for NOx emission reduction in new and existing boilers with heat 

capacities less than 100 mmBtu/hr. 

The control techniques most frequently applied include burner 

modifications and flue gas recirculation. 

5 
1. Burner Modifications 

Burner modifications for NOx control involve changing the design of a 

standard burner in order to create a larger flame. Enlarging the flame results in 

lower flame temperatures and lower thermal NOx formation which, in tum, results 

in lower overall NOx emissions. The technology can be applied to most boiler 

types and sizes. Nearly all burner modifications or low NOx burners use some 

method of staged air or staged fuel technique. 

· Staged combustion burners achieve lower NOx emissions by staging the injection 

of either air or fuel in the near burner region. The division of combustion air 

reduces the oxygen concentration in the primary burner combustion zone, 

lowering the amount ofNOx formed ~;~nd increased the amount ofNOx reducing 

agents. Secondary and tertiary air completes the combustion downstream of the 

primary zone, lowering the peak temperature and reducing thermal NOx 

formation. 

Since NOx is highly dependent on peak flame temperature, this is an 

effective method to moderate thermal NOx reductions. However, given that the 

existing burners are almost 20-years old, modification of the burners is not 

recommended. As a result, this option has been eliminated from further 

consideration. 

2. Flue Gas Recirculation 

Flue gas recirculation involves recycling a portion of the combustion gases / ,.,c,e.c 

from the stack to the boiler windbox. Introducing some of the flue gas back into IJ. 

the combustion air reduces peak flame temperatures. The incoming air is diluted .1\f,. /. :}a~ , 

and the oxygen concentration in the combustion zone is reduced. During J.>csi,&lc. d "c 

combustion, the recirculated flue gases also absorb some of the heat and thereby + ,, rc -l'l~·f.;+ 

reduce the peak combustion temperatures. Substantial modifications are required "' 

to retrofit a boiler with flue gas recirculation and room to install the additional 

equipment, gas recirculation fan, dampers and ducting is not available. 

As a result, this option has been eliminated from further consideration 

c. Post-Combustion Techniques 

Post combustion control methods include Selective Non-Catalytic 

Reduction (SNCR) and Selective Catalytic Reduction (SCR). 

6 
1. Selective Non-Catalytic Reduction 

Selective non-catalytic reduction involves the injection of a NOx 

reducing agent, such as ammonia or urea, into the boiler exhaust gases at a 

temperature of approximately 1400- 1600°F. The ammonia or urea breaks 

down the NOx in the exhaust gases into water and atmospheric nitrogen. 

Selective non-catalytic reduction can reduce NOx emissions up to 

70%. However, the technology is extremely difficult to apply to industrial 

boilers that modulate or cycle frequently, since the ammonia (or urea) must 

be injected in the flue gases at a specific flue gas temperature. 

In boilers (like Southerly's) that modulate or cycle frequently, the 

location of the exhaust gases at the specified temperature is constantly 

changing. Thus, it is not feasible to apply selective non-catalytic reduction 

to industrial boilers that have high turndown capabilities and modulate or 

cycle frequently. 

Accordingly, SNCR is not considered a technically feasible option 

for NOx emission reduction and has been dropped from further 

consideration. 

2. Selective Catalytic Reduction 

Selective Catalytic Reduction involves the injection of ammonia in 

the boiler exhaust gases in the presence of a catalyst. The catalyst allows 

the ammonia to reduce NOx levels at lower exhaust temperatures than 

selective non-catalytic reduction. 

Unlike selective non-catalytic reduction, where the exhaust gases -· 

must be approximately 1400-1600°F, SCR can be utilized where exhaust 

gasses are between 400°F and 1200°F, depending on the catalyst used. SCR 

can result in NOx reductions of up to 90%. However, it is _s_ost!Y to use and 

can rarely be cost justified on boilers with inputs less than 100 MMBtu/hr. 

As a result, this option has also been dropped from further 

consideration.

Typical Burner Installation Procedure 

Ref. : BR-9001 R1 

Burner General arrangement Drawing. 

1. Refractory throat. 

Natcom burner throat should b·e fabricated using a refractory material that can accommodate 

high temperatures and very low shrinkage when cured. Plastic poundable or castable 

refractory with 80% alumina content is recommended. 

The throat must be cylindrical in shape with the ID of the refractory material equal to the ID of 

the burner stainless steel throat liner. 

A qualified, experienced tradesman should perform the refractor work. He should determine: 

Procedure for installing the refractory. 

Type of refractory best suited for the application. 

Location and type of anchors to be used. 

Need and location of Expansion joints if necessary. 

Curing schedule and procedure. 

2. Positioning of burner components: 

The geometry (positioning) of the burner components significantly influence the burner 

performance. Consequently it is important to locate the burner components correctly with 

respect to the boiler front wall. Please refer to the pertinent drawings for your burner in the 

instruction manual. 

Dimension "A" locates: 

Flame stabilizer 

Oil Atomizer Guide pipe end 

Gas stabilizer injector. 

Dimension "B" locates: 

Primary gas injectors. 

Staged gas injectors. 

Mixed Gas injectors. 

Dimension "C" locates: 

Hyper-Mix impulse lance. 

Windbox is located per burner horizontal centerline axis. 

Front of Windbox must be perpendicular to the burner central axis. 

Circular opening at front of windbox must be centered about the boiler front wall opening. 

Front face of the windbox must be parallel to the boiler front wall. 

3. WELDING: 

Burner throat flange (Material SS304L) must be welded to the boiler front wall. Use 

ER309L welding rod. 

Burner throat (material SS304L) weld to burner throat flange after positioning per 

dimension A in section 2 above. Use welding rod ER308L or ER309L. 

Windbox (material G44.21-44W) to be seal welded to boiler front wall after having been 

positioned onto boiler front wall. Use E7018 welding rod. 

Hyper-Mix ring (material G44.21-44W, ASTM A36) to be tack welded to the burner throat 

using the guide tabs on the ring. Use ER309L welding rod. 

NB. To facilitate transportation some components are temporarily positioned and fastened 

using braces that are painted fluorescent green. These braces should be removed prior 

to installation.

Re: Southerly Wastewater Treatment Center 

February 25, 2008 

NOx RACT Applicability -New Fluidized Bed Incinerators 

Dear Ms. Rehner: 

Thank you very much for taking the time last week to discuss with me the reasons 

why the City of Cleveland Division of Air Quality (CDAQ) and Ohio EPA feel that the 

NOx RACT Rules (OAC 3745-110) apply to Southerly's new fluidized bed incinerators. 

The Northeast Ohio Regional Sewer District (NEORSD) agrees that NOx RACT 

applies to Southerly's four existing multiple hearth incinerators (MHis). As a result, we 

plan to submit a NOx RACT Study for the existing MHis, unless Ohio EPA approves a 

determination that the study is not necessary for incinerators (like Southerly's MHis) that 

are being replaced. 

On the other hand, after again reviewing the terms and conditions contained in 

OAC 3745-110, we firmly believe that NOx RACT does not apply to Southerly's new 

fluidized bed incinerators for the following reasons: 

1. NOx RACT does not apply to modified sources that are not boilers, 

engines or turbines. The rule establishes two criteria for a new or modified 

source at OAC rule 3745-11 0-02(A) (2): 

(a) The source, as defined in rule 3745-110-01 of the Administrative Code, is a 

very large boiler, large boiler, mid-size boiler, small boiler, stationary 

combustion turbine, or stationary internal combustion engine; and 

3900 Euclid Avenue 1 Cleveland, OH 441151 P: (216) 881-6600 IF: (216) 881-2738 
(b) Except where the emission limitations and requirements of an 

applicable new source performance standard under 40 CFR Part 60 are 

more stringent than the emission limitations and requirements of this 

chapter, any new or modified source issued a permit-to-install after 

January 1, 2008, shall comply with the requirements of this chapter. 

Since the rule uses the term "and" both of these criteria must be satisfied for 

the rule to be applicable. That is, "any new or modified source" in (b) is 

necessarily limited by how a "source" is defined in (a). Therefore, modified 

sources, like the Southerly incinerator replacement project, that are not boilers, 

engines or turbines should not be subject to NOx RACT. 

2. This does not mean that new and modified sources will be installed 

without technically feasible and economically reasonable NOx controls. 

The same criteria that are used to determine NOx RACT under Section 110 

should be applied in the PTI process to deterinine the Best Available 

Technology (BAT) for NOx reduction. NEORSD is proposing low NOx 

burner technology for the fluidized bed incinerators, which is reflected in the 

proposed NOx rate in our PTI application. 

3. To interpret subsection 2(b) of the NOx RACT rule as applying to any 

new or modified source could not have been the intent of the rule since: 

(a) NOx RACT studies are only necessary for existing sources that 

are not conducting a BAT analysis associated with a PTI process. 

Requiring a NOx RACT study with certified engineers, in addition to a 

BAT analysis, is redundant. 

(b) NOx RACT studies require data from existing source operations 

(maximum annual production rates, maximum daily and annual NOx 

emission rates, documentation of existing control efficiency and any testing 

performed) that are not available from new sources or modified 

configurations. These studies were not intended for new sources. 

(c) NOx RACT studies require a schedule for retrofitting the units. New and 

modified sources are required to implement NOx controls upon startup. 
(d) As we interpret the NOx RACT applicability, only the new and modified 

boilers, engines and turbines that have numeric NOx RACT limits in the 

rule are required to comply with the NOx RACT rule. These numeric 

standards are easily incorporated into the PTI along with the various 

recordkeeping and reporting requirements. Other sources achieve NOx 

controls by employing BAT. 

Please do not hesitate to contact me at 216-881-6600 ext. 6405 if you have any 

questions or require additional information concerning the items contained within this 

letter.
