Kansas agency seeks comment on Tecumseh NOx control project

The Kansas Department of Health and Environment is taking public comment until Feb. 5 on a draft air construction permit that covers installation of separated overfire air and other NOx controls on the coal-fired Unit 8/10 at the Tecumseh plant of Westar Energy.

If requested by the public, the department would hold a Feb. 6 public hearing in Topeka on this permitting.

Westar Energy owns and operates the Tecumseh Energy Center (TEC), an existing coal-fired plant, located in Tecumseh, Shawnee County, Kansas. Westar is proposing to make certain modifications to the existing burner and combustion system on the Unit 8/10 boiler at the TEC.

“The burner and combustion system modifications include installation of new low NOX burners (LNBs), windbox air actuators, windbox dampers, coal feeders, coal piping and coal piping support, the installation of separated overfire air (SOFA) ducting, dampers, and air tips, and boiler tuning,” said a department project summary. “This project will result in an overall decrease in NOX emissions. As a result of lowering NOX emissions there may be an increase in carbon monoxide (CO) emissions. With the increase in CO emissions a decrease in carbon dioxide (CO2) emissions is anticipated.”

The Westar website said that Tecumseh is a 242-MW plant fueled by low-sulfur coal. “A Low NOx system has been installed on one of the units at TEC with the second installation scheduled in 2013,” the website added.
