1 .O INTRODUCTION

On November 20, 1991, Air Consulting and Engineering, Inc. (ACE), conducted

particulate emission testing on the Dual Wet Scrubber Outlet of Boiler 5 at

Sugar Cane Growers Cooperative of Florida (Sugar Cane Growers) located in

Belle Glade, Florida.

Testing was performed to demonstrate compliance with the current Florida

Department of Environmental Regulation (FDER) operating permit.

United States Environmental Protection Agency (EPA) Method 5 was utilized for

the emission testing.

Mr. Sterling Jordan of the FDER observed a portion of the testing.

Mr. Blas Marin of Sugar Cane Growers coordinated testing and provided

production data.

Page 6: Reference Number: 39 - epa.gov

2.0 SUMMARY AND DISCUSSION OF RESULTS

Boiler Number 5 demonstrated compliance with the permit conditions.

Table 1 is a summary of the emission results and flue gas parameters.

Particulate emissions averaged 51.36 pounds per hour (IbslHr) and 0.170 pounds

per million BTU (IbslMMBTU) which is within the allowable emissions of 70.58

Ibs/Hr and 0.233 IbslMMBTU.

Complete emission summaries, field data sheets and laboratory data are

presented in Appendices A, B, and C, respectively.

Production rate summaries are provided in Appendix D. This data was obtained

from control room recordings of steam flow, temperature, and pressure as

well as feed water temperature and pressure. Residue integrator and oil meter

readings were recorded at the beginning and end of each particulate run.

3.0 PROCESS DESCRIPTION AND OPERATION

The Number 5 Boiler at Sugar Cane Growers is a spreader stoker design used

primarily for residue fuel firing. Supplemental oil firing was also utilized

for the emission test. The boiler averaged 178,257 IbslHr steam production

over the three run test period.

Oil meters, steam integrators, and other production monitoring devices were

rigorously calibrated prior to the production season.

4.0 SAMPLING POINT LOCATION

The sampling point location (Figure 1) consists of dual scrubber outlet

stacks, each 64" in diameter. Each stack has two sample ports 90 degrees

apart. The ports on the south stack are located 132 from an upstream

disturbance and 64" from the outlet.

Twentyfour test points were sampled on each stack for each test run. The

traverse were located as shown below. The stack configuration is such that

there was no reason to evaluate the presence of cyclonic flow.

5.0 FIELD AND ANALYTICAL PROCEDURES

5.1 Particulate Matter Sampling and Analysis--€PA Method 5 /Glass Probe)

Particulate matter samples were collected by the particulate matter emission

measurement method specified by the United States Environmental Proteciion

Agency. A schematic diagram of the sampling train used is shown in Figure 2.

All particulate matter captured from the nozzle to, and including, the filter

was included in the calculation of the emission rate of particulate matter.

PREPARATION OF EQUIPMENT

1, FILTERS - Gelman type "A" filters were placed in a drying oven for t w o hours a t 105 degrees C, removed and placed in a standard desiccator containing indicating silica gel, allowed to cool for two hours, and weighed to the nearest 0.1 rng. The filters were then re-desiccated for a minimum of six hours and weighed to a constant weight (less than 0.5 rng change from previous weighing). The average of the two constant weights was used as the tare weight.

2. NOZZLE, FILTER HOLDER, AND SAMPLING PROBE - The nozzle, filter holder, and sampling probe were washed vigorously with soapy water and brushes, rinsed with distilled water and acetone. and dried prior to the test program. All openings on the sampling equipment were sealed while in transit to the test site.

IMPINGEFIS - The Greenburg-Smith impingers were cleaned with a warm soapy water solution and brushes, rinsed with distilled water and acetone, and dried. The impingers were sealed tightly during transit.

3.

TEST PROCEDURE

Prior to performing the ac:ual particulate matter sample runs, certain stack

and stack gas parameters were measured. These preliminary measurements

t

Page 13: Reference Number: 39 - epa.gov

included the average gas temperature, the stack gas velocity head, the stack

gas moisture content, and the stack dimensions at the point where the tests

were being performed. The stack gas temperature was determined by using a

bi-metallic thermocouple and calibrated pyrometer. Velocity head measurements

were made with calibrated type "S" pitot tube and an inclined manometer.

Velocity head measurements of 0.05 inches H20 or less were measured utilizing

a micromanometer.

The sampling traverse points were selected so that a representative sample

could be extracted from the gas stream. The traverse points were located in

the center of equal areas, the number of which were dependent upon the

distance upstream and downstream from f low disturbances.

Each particulate matter test run consisted of sampling for a specific amount

of time at each traverse point. The type "S" pitot tube was connected to the

sampling probe so that an instantaneous velocity head measurement could be

made a t each traverse point while making the test run. The stack gas

temperature was also measured a t each traverse point. Nomograph were used to

calculate the isokinetic sampling rate at each traverse point during each test

run.

The gases sampled passed through the following components: a stainless steel

nozzle and glass probe; a glass fiber filter; two impingers each with 100 mi

Page 14: Reference Number: 39 - epa.gov

of distilled deionized water; one impinger dry; one impinger with 200 grams of

silica gel; a flexible sample line; an air-tight pump; a dry test meter; and a

calibrated orifice. The second impinger had a standard tip, while the first,

third, and fourth impingers had modified tips with a 0.5 inch I.D. opening. :

Sample recovery was accomplished by the following procedures:

1. The pre-tared filter was removed from its holder and placed in Container 1 and sealed. (This is usually performed in the lab.)

2. All sample-exposed surfaces prior to the filter were washed with acetone and placed in Container 2, sealed and the liquid level marked.

3. The volume of water from the first three impin ers was measured for the purpose of calculating the moisture in t it e stack gas and then discarded.

4. The used silica gel from the fourth impinger was transferred to the original tared container and sealed.

LABORATORY ANALYSlS

The three sample containers from each sample run were analyzed according to

the following procedures:

1, The filter was dried a t 105 degrees C for three hours, desiccated for a minimum of one hour, and weighed to the nearesf 0.1 mg. A minimum of two such weighings six hours apan was made to determine constanr weight.

2. The acetone from Container 2 was transferred to a tared beaker and evaporated to dryness a t ambient temperature and pressure, desiccated for 24 hours, and weighed to the nearest 0.1 mg. A minimum of two such weighings six hours apart were made to determine constant weight.

3. The used silica gel in its tared container was weighed to the nearest 0.1 gram.

The total sample weight included the weight of material collected on the

filter plus the weight of material collected in the nozzle, sampling probe,

and front half of the filter holder.

STAXDARD METER CALIBRi\TION Meter Xumber 1040616

Air Consulting and Engineering. Inc. (ACE) uses a dry gas meter for the calibration standard. This meter has been calibrated against a wet test meter in triplicate. This data was used to generate a standard meter calibration curve (see next page). Field meter calibrations are corrected to this curve using the following formula:

Y X Y s = Y a

Ya = actual' ratio of field meter to standard meter

Ys = ratio of standard meter to wet test meter at a given

Y = corrected ratio of field meter

flow rate (from Calibration Curve)

The dry standard meter was calibrated on June 11. 1991. and is checked and/or recalibrated at least annually.
