Coal Fired Boiler Emissions Test - EPA

Jun 15, 1994 · Entropy tested the exhaust gases from the Unit 1 coal-fired boiler. The furnace burns bituminous coal. Gases from the combustion furnace pass through two electrostatic precipitators (ESPs) to control particulate. Gases exiting the ESPs pass through a flue gas desulfurization unit (FGD), to remove SO2, and are then exhausted through a stack.
