2.0 PROCESS

DESCRIPTION This section contains a brief description

of the brick kiln, the control devices and an air flow schematic. 2.1 Discussion Triangle Brick operates

three natural gas fired kilns (Kiln Nos. 1, 2, and 3) at its facility in Merry Oaks, North Carolina.

Kiln Nos. 1 and 2 vented emissions

through a common

scrubber CD-K1K2

and Kiln No. 3 vented emissions

through the CD-K3 scrubber

control device. A twenty-four

car shuttle was conveyed through Kilns 1 and 2 yielding

approximately

11.855 tons/hr of bricks fired for the April 20, 2006 test. During the Kiln 3 test on May 4, 2006, a seventeen

ear shuttle was conveyed

through the kiln yielding approximately 23.776 tons/hr of bricks fired. This production

weight information

was provided

by Kathy Wheeler of Triangle Brick. The fiue gases were withdrawn

from the gas-fired

tunnel(s)

through a scrubber, I.D. fan, and stack to the atmosphere.

Figure 1 details the air flow schematic. Production data was recorded

by Triangle Brick personnel

and is presented

in Appendix

METHODS This section describes

the sampling

strategy, sampling

and analytical

methods,

and quality assurance/quality control procedures

implemented

during this project. 3.1 Sampling

Strategy The sampling

and analytical

procedures

used during this test program

were those established

by the US EPA. The sampling

runs were conducted

in triplicate

to validate the sampling.

Tests were conducted during normal operating

conditions. 3.2 Sampling

and Analytical

Procedures The US EPA methods

used in this sampling

program were Method 1 for the location of sampling

ports and points, and determination

of cyclonic flow, Method 2 for volumetric

flow rate determination,

Method 3 for the determination

of dry molecular

weight of the stack gas, Method 4 for the determination

of moisture

in the stack gas. Methods

5 and 26A were used for the determination

of particulate,

hydrogen

chloride and hydrogen fluoride emissions.

A sampling

and analysis synopsis for these methods is discussed

briefly in the following subsections.

These test methods

are available

in the Code of Federal Regulations

Volume 40, Part 60 or by request from Trigon. 3.3 Sampling

Ports, Traverse

Points and Cyclonic

Flow Determination The sampling

locations

were prepared

according

to the criteria in Method 1. The duct diameters

upstream and downstream

from the sampling

ports were determined

prior to sampling.

The number of traverse points was chosen with respect to sampling

port location.

For particulate

traverses

Method 1 specifies

a minimum of 8 traverse points for sampling

ports located >8/>2 downstream/upstream stack diameters

from flow disturbances and 24 traverse points when located >9/>0.5.

The amount of cyclonic flow was determined according to the criteria detailed in Method 1. 3.4 Stack Gas Vdocity

and Volumetric

Flow Rate Determination Method 2 is used for determining

the average gas velocity in a stack from measurements

of gas density and the average velocity head with a Type S (Stausscheibe

or reverse type) pitot tube. This method is applicable for quantifying

gas flows which meet the criteria of Method 1.In principle,

measurements

of velocity head and temperature

are performed

at the traverse points specified

by Method 1. A properly

scaled differential

during the traverse.

A 0 to 10 inches of water inclined manometer

was used as the differential

pressure gauge. During this project, the sampling

locations

met the criteria detailed in Method 1. Gas stream density was determined by Method 3. Moisture

determination

was performed

by Method 4. The principal

components of the gas velocity measurement

system were sequentially:

• A calibrated

stainless steel Type S pitot tube and Type K thermocouple;

• Leak-free

interface

tubing between pitot tube and differential

pressure gauge;

• A 0 to 10 inch inclined manometer;

and

• An NIST traceable

pyrometer. The apparatus

was set-up according

to manufacturer

and reference

method recommendations.

Pre-test and post-test leak checks were conducted

using procedures

outlined in Method 2, Section 3.1. Velocity

head and temperature measurements

were performed

at the traverse points specified

by Method 1. The atmospheric and static pressure

of the stack was also determined

for the velocity head readings.

The volumetric

flow rate calculations

used were those specified

in Method 2, Section 5. A more comprehensive

explanation

of the reference

method is detailed

in the Quality Assurance

Field Procedure

2. 3.5 Dry Molecular

Weight Determination Method 3 is applicable

for determining

carbon dioxide and oxygen concentrations

and dry molecular

weight of a sample from a gas stream of a fossil-fuel

combustion

process.

This method may also be applicable

to other processes

where it has been determined

that compounds

other than carbon dioxide, oxygen, carbon monoxide, and nitrogen are not present in concentrations

sufficient

to affect the results. In principle,

a gas sample was withdrawn

from the emission

source by multi-point,

integrated

sampling.

The collected sample was then analyzed

for percent carbon dioxide, percent oxygen, and percent carbon monoxide. The dry molecular

weight determination

was performed

by an Orsat analyzer. During this project, the gaseous components

were collected

using a Method 3 sampling

system following the analytical

procedures

outlined

in the reference

method.

The principal

components

of the sampling system were sequentially:

• A stainless steel probe;

• A one-way squeeze bulb, to transport

the sample to the Tedlar bag;

• A saturator

tube to remove particulate

matter and excess moisture;

and

• A leak-free

Tedlar bag equipped

with a double-end

shut-offquick

connect. The analysis

was performed

with an Orsat type combustion

gas analyzer

within 8 hours of sample collection. The dry molecular

weight was calculated

using Equation

3-1, Section 7 of Method 3. The analyzer was maintained

and operated

according

to the instructions

recommended

by the manufacturer

and in accordance

with Method 3 criteria. The analyzer was leak-checked

according

to Section 6 of Method 3. The oxygen reagent was validated

by analyzing

a sample of ambient air which must meet the specifications of 20.9% + 0.3%. 3.6 Moisture

Determination Method 4 involves

the determination

of stack gas moisture.

The moisture

content is used to correct the emission concentration

or mass emission

rate to a dry basis. EPA Method 4 and FieM Procedure

4 of the QA Handbook

was used to measure

stack gas moisture

content.

Field Procedure

4 provides

detailed information on the application

of Method 4. Preliminary flue gas moisture

content (for purposes

of setting the isokinetic

flow rate) was determined

using wet bulb/dry

bulb thermometers

and partial pressure,

vapor and saturated

vapor pressure

equations.

This technique is described

in Method 4 and is summarized

below:

• Moisten the wet bulb thermometer

wick with deionized

water;

• Insert both thermometers

into the flue gas stream and monitor the wet bulb temperature;

• When the wet bulb temperature

has stabilized,

record both the wet bulb and dry bulb thermometer temperatures;

and

• Calculate

the flue gas moisture

content (PMV) using the appropriate

equations. The moisture

content for emission

rate calculations

was determined

in conjunction

with the Method 5/26A and Method 29 isokinetic

sampling

trains. The reference

method involves the withdrawal

of gaseous and particulate pollutants

from the emission

source at an isokinetic

rate using a Method 5 sampling

system. The sampling and analytical

procedure

for reference

Method 4 will be discussed

in detail in the following sections with the isokinetic

sampling

procedures.

Matter,

Hydrogen

Chloride,

and Hydrogen

Fluoride

Sampling Testing for particulate

matter, hydrogen

chloride,

and hydrogen

fluoride was performed

according

to Method 26A procedures.

Gaseous

and particulate

pollutants

were withdrawn

isokinetically

from the emission source and collected

in a multi-component

sampling

train. In principle,

particulate

matter that was condensed at or above the filtration

temperature

of approximately

248 degrees Fahrenheit

was collected

on a tared quartz fiber filter. The gaseous components

were then bubbled through a measured

volume of 0.1N sulfuric acid and 0.1N sodium hydroxide

to determine

the moisture,

hydrogen

chloride,

and hydrogen fluoride content of the emission

source.

The principal

components

of the sampling

system were sequentially:

• A borosilicate

glass sample nozzle and probe liner;

• A heated (248°F +25°F) probe and filter assembly

with tared quartz fiber filter;

• An impinger

train consisting

of five sequential

impingers.

Impingers

one and two containing 100 ml each of an absorbing

solution

consisting

of dilute sulfuric acid (0.1N H2SO4). Impingers three and four contained

100 ml of dilute sodium hydroxide

(0.1N NaOH) followed by a final impinger

containing

200 grams of silica gel; and

• A metering

system capable of maintaining

an isokinetic

sampling

rate and accurately determining the sample volume according

to specifications

in APTD-0581. Sample clean up began immediately

after each test run. The filter, which collected

the sample, was carefully removed

from the Teflon filter support and sealed in a Petri dish. The nozzle, probe liner, and front filter-half

of the filter assembly

were rinsed with acetone into a glass storage container,

which was sealed, and the liquid level marked.

The sample containers

were transported

to Trigon's Air Quality Laboratory in Charlotte,

North Carolina

for particulate

matter analysis. Hydrogen chloride and hydrogen

fluoride were collected

in the 0.1N sulfuric acid solution in impingers

one and two. The liquid in the first two impingers

was measured

to the nearest milliliter

and recorded

in order to determine

the moisture

content. The collected

sample was placed in a high-density

polyethylene

(HDPE) storage container

along with the deionized

water rinse of impingers

one, two, three and connecting glassware. The container

was sealed and the liquid level was marked. The moisture

collected

by the silica gel in the sixth impinger

was determined

to the nearest 0.1 gram. Collected condensate

measurements

were recorded

on the "moisture

determination

and sample recovery data analysis"

form. The samples were then shipped to Element One Laboratories

of Wilmington,

where they were analyzed

by ion chromatography.

Results of the hydrogen

chloride and hydrogen

fluoride analysis along with Element One's quality assurance

data package can be found in Appendix

C. The particulate

matter analyses began by transferring

the acetone samples to tared beakers.

These samples were taken to dryness, and then placed in a desiccator

along with the filters for an initial drying period of 24 hours. The particulate

mass was determined

gravimetrically.

The tare weights of the filters and beakers were subtracted

from the final weights to determine

the gross particulate

weight.
An aliquot of the reagent grade acetone was analyzed

to determine

the blank correction

factor. The acetone rinse (corrected

for the blank) was added to the filter catch to obtain the total particulate

weight.

The particulate samples and method blanks were analyzed

by Trigon Engineering

personnel. The laboratory

analyses and chain of custody documentation

can be found in Appendix

C. 3.9 Sampling

Ports and Points The dimensions

of the stacks and the location of the sampling

ports and points are detailed in Figures 2 and 3. Method 1 sampling

criteria was maintained.

The stack cross section for Kiln Nos. 1 and 2 was divided into 12 equal areas and the Kiln No. 3 stack was divided into 24 equal areas. The ports for each stack were labeled A and B. During the test runs on Kiln Nos. 1 and 2, the traverse points were sampled for 7 minutes per point for a run duration of 90 minutes and each point for Kiln No. 3 was sampled for 4 minutes, which yielded a total test time of 96 minutes.

Assurance

and Quality

Control Trigon has established

quality assurance

and quality control (QA/QC)

guidelines

for providing

quality sampling and analytical

data from source tests. These QA/QC procedures

were implemented

to ensure the acceptability and reliability

of the data generated.
In summary,

an appropriate

degree of data quality was maintained

throughout

this project. Leak checks and isokinetic QA criteria were met. The sampling

trains were leak checked prior to and immediately

after sampling. Leak rates for the isokinetie

sampling

trains were less than the maximum

criterion of 0.02 cubic feet per minute. The sampling

rates were also within the 100% •:10% criterion.

Quality control procedures for the particulate

matter determinations

have included the analysis of an acetone rinse blank, which must be less than 0.001% for the acetone residue.

Spike and recoveries

were performed

for the sampling methodologies used. An analyte spike was added to a portion of a prepared

sample and recovered

to within 70 and 130 percent of the known concentration.

The results of the QA criteria for this project are summarized in the following

tables and can be. Detailed

results of the method blanks are reported
