Owner Objective

Westar Energy, headquartered in Topeka, Kansas, owns and operates coal, natural gas nuclear, gas-to-energy and wind generating facilities in Kansas. Westar’s Jeffrey Energy Center, located in St. Mary’s, is a 2,155 megawatt plant commissioned in 1978 and is the largest such plant in the entire state. Westar needed to conduct total suspended particulate matter (TSP) testing for determining the control efficiency of the electrostatic precipitator (ESP) on electric generating Unit 2 at the Jeffrey Energy Center.

CEC Approach

CEC was contracted by Westar to conduct the total suspended particulate matter (TSP) testing. United States Environmental Protection Agency (USEPA) Methods 1, 2, 3A, 4, and 17 were used to determine the sampling point locations, flow, molecular weight, moisture, and TSP in the flue gas. Method 3A was used to determine stack gas oxygen (O2) and carbon dioxide (CO2) for determining the stack gas molecular weight determination and for calculating the pounds per million British thermal units (lbs/mmBtu).

The exhaust gases from the boiler burn chamber are exhausted through the pollution control equipment and exhausted via the stack, so the ESP efficiency testing was conducted at the east and west ESP inlet and outlet locations.

CEC provided on-site preliminary results using CEC’s mobile laboratory equipped with a solvent fume hood, dessicators and gravimetric balance. CEC also prepared the sampling protocol, conducted the emissions testing, and prepared the final emissions testing report.
