Description of the source (including control equipment). Please see the attachments for source or process flow diagram: The PCPP is an independent electrical power generating facility which uses energy from fuel oil, waste coal, wood waste, and non-hazardous organic tars/oils from manufactured gas and coke plants for transmission of electricity to the Reliant Energy, Piney Hydroelectric Power Plant substation interconnection. The facility produces a base load of 32 MW net of electricity. Water is drawn from the Piney Reservoir on the Clarion River for boiler and cooling tower makeup, service water, and potable water. Waste coal fuel and limestone (for SO2 control) are delivered by truck to the site and ash products are trucked away for disposal.
The facility includes one circulating fluidizing bed (CFB) boiler producing 290,000 pounds per hour (lb/hr) of steam at 1,310 pounds per square inch gauge (psig) pressure at 955°F. The boiler is manufactured by Tampella Power Corporation of Williamsport, Pennsylvania. The turbine-generator set is an Asea Brown Boveri VAX type unit exhausting steam at 2.5" mercury (Hg) to a water-cooled steam surface condenser. Flue gas from the boiler enters an 8-module pulse jet-type fabric filter baghouse manufactured by Amerex, Inc. of Woodstock, Georgia. The design flow rate is 156,000 actual cubic feet per minute (ACFM) at 300°F with an inlet loading range of 8 to 30 grains/ACFM of flyash. An induced draft fan draws flue gas from the baghouse and discharges it into the base of a 275' tall concrete chimney. Industry/SCC/NAIS221112
