Airflow Problems Lead to Fly Ash Accumulation

摘要

The Kansas City Power & Light (KCP&L) La Cygne Generating Station provides 1,532 MW of peak power to customers from its site south of Kansas City. La Cygne Unit 1 is an 815 MW Babcock & Wilcox (B&W) cyclone boiler with overfire air (OFA) and selective catalytic reduction (SCR) nitrogen oxide (NOx) controls. It is the second-oldest B&W wet flue gas desulfurization (WFGD) installation in the country. Unit 2 is a 717 MW B&W pulverized coal boiler with low NOx burners (LNBs), OFA and electrostatic precipitator (ESP) particulate control. Unit 1 burns a blend of 90 percent Powder River Basin (PRB) and 10 percent local Missouri coal.
