1.0 INTRODUCTION

On April 16, 2009, Tampa Electric Company’s, Environmental Services, Air Services 

Group performed Volatile Organic Compounds (VOCs) source emission tests, on Unit 

No. 1 at the Polk Power Station (PPS). Unit No. 1 is a combined cycle combustion 

turbine generating unit. The combustion turbine was fired with syngas from the solid 

fuel gasification system. A blend of petroleum coke and bituminous coal was gasified 

for this test. Operations at PPS are authorized by the Florida Department of 

Environmental Protection (FDEP) and permitted via Title V Permit No. 1050233-016-AV,

corrected to Average Ambient Temperature recorded during the test period. 

2Unit Load (% of permit) is Heat Input Divided by Maximum Heat Input times 100. 

The Volatile Organic Compounds (VOCs) mass emission rate was derived from three 

Reference Method 18 test runs. The calculated average VOCs emission rate was <1 

lbs/hr. The FDEP permitted emission rate is 3 lbs/hr based on a 30-day rolling average. 

During the test Unit No. 1 was operated at an average heat input of 1687 mmBtu/hr. 

The FDEP permitted heat input is 1755 mmBtu/hr, at an ambient temperature of 59o 

(corrected to 1749 mmBtu/hr based on an average inlet vane temperature of 86o F, and 

the manufacturer’s heat input correction curve for this unit). The unit operated at 96% 

of permitted capacity.

3.0 SOURCE DESCRIPTION/TEST PROCEDURES

Polk Power Electrical Generating Station is located at County Road 630 approximately 

13 miles southwest of Bartow, Polk County, Florida. Unit No. 1 is a Combined Cycle 

Combustion Turbine generating unit, with a net capacity of 192 MW when fired with 

Syngas fuel. The source sampling location consists of a circular stack 19 feet in 

diameter with four sample ports located 90 degrees apart on the stack circumference. 

A diagram of the stack sampling location is included along with other pertinent 

information on the test site. 

Volatile Organic Compound sampling was performed in accordance with USEPA 

Reference Method 18 “Measurement of Gaseous Organic Compound Emissions by Gas 

Chromatography”. Analysis was performed by Enthalpy Analytical, Inc. Three samples 

were collected from the stack and one sample was collected at the stack testing location 

for a background reading. The background reading was collected with the sampling 

probe sitting on the decking at the sampling location. All four analytical results returned 

concentrations between the Minimum Detection Limit (MDL) and the Limit of 

Quantification (LOQ). Subtracting the background reading from the stack readings 

resulted in a concentration value below the MDL. The MDL concentration was 

substituted in the subsequent mass emission calculation. 

Plant operational and fuel composition data was taken from the Plant Information (PI) 

server system.

Notations to Data:

All results (three samples and backgroud) returned analytical results between the

Minimum Detection Limit of 0.112 ppm propane and the Limit of Quantification of

3.00 ppm propane. Subtracting the background from the samples, as allowed by

permit, yields concentration values below the Minimum Detection Limit.

As a conservative means of demonstrating compliance with the permitted emissions

rate, the value of the Minimum Detection Limit (0.112 ppm propane) was used to 

calculate the mass emission rate.

VOC, lb/scf calculated as:

ppm VOC x Cf 

where:

Cf = Mole wieght of propane (44.017 lb/lb-mole) x 10-6 / (385.15 scf/lb-mole)

1.145E-07 lbs/dscf

VOC, lbs/hr calculated as:

VOC, lb/scf x Stack Flow, scf/hr
