Boiler MACT Assessment Study
Stanley Consultants evaluated an existing coal-fired rotary stoker boiler and identified options for compliance with Area Source Boiler MACT regulations. The boiler was installed in 1965 and is rated for 50,000 PPH and produces saturated steam at 105 psig. Existing emission controls included a dry-sorbent injection system, rotoclone, and a baghouse.
Emissions for the boiler were examined and corrective actions were determined for Boiler MACT compliance. Conceptual design, capital; and operations and maintenance cost estimates were developed for retrofit of powdered active carbon systems to control mercury emissions.
