Coal-Fired Plants in the USA - Missouri
Asbury
Location: MO
Operator: Empire District Electric Co
Configuration: 1 X 200 MW, 1 X 20 MW
Operation: 1970-1986
Fuel: subbituminous coal, TDF
Boiler supplier: B&W
T/G supplier: Westinghouse
Quick facts: Although built as a mine-mouth plant, Asbury was converted to PRB coal in 1990. A single cyclone boiler supplies the main T/G set and a second T/G set added about 15 yrs after operation started. In 2002, operators began adding shredded tires to the fuel mix and these now account for about 2% of total fuel burn by weight. In the first three years of TDF consumption, the plant burned about 50mn lbs of TDF equivalent to 2.5mn tires making Asbury one of Power magazine's Top Plants in 2005.
