Description of the source (including control equipment). Please see the attachments for source or process flow diagram: Cambria Cogen operates two identical CFB Boilers (Flues A and B) at their facility located in Ebensburg, Pennsylvania. Each boiler is a Pyropower CFB design, which utilizes limestone injection into each boiler’s combustion zone to capture SO2. Flue gas leaving each boiler passes through its own baghouse for particulate matter (PM) control, and is exhausted through individual flues contained in a combined stack shell. Each of the boilers has a firing rate of approximately 560 million British thermal units per hour (MMBtu/hr) of bituminous coal refuse (“gob”) to generate steam for export and for the production of electricity. The electricity production rating is 85 MW for the combination of each boiler. Industry/SCC/NAIS 221122
