Description of the source (including control equipment). Please see the attachments for source or process flow diagram: Dynegy owns and operates the Havana Power Station, located near Havana, Illinois. The facility consists of eight (8) residual oil-fired boilers (Units 1 through 5) and one (1) coal-fired boiler (Unit 6), with associated steam turbines for electricity generation.
The Unit 6 coal-fired boiler is equipped with a hot-side electrostatic precipitator (ESP) for the control of PM. Nitrogen oxide (NOX) is controlled using selective catalytic reduction (SCR). A fabric filter baghouse with activatedcarbon injection provides additional PM and mercury control. Sulfur dioxide (SO2) is controlled by utilizing lowsulfur Powdeer River Basin (PRB) coal.
The spray dryer absorber (SDA) system, while physically installed, is not in service at this time. The flue gas currently passes through the modules; a small amount of water is added to cool the flue gas.
The testing described in this document was performed at the Unit 6 Stack. Industry/SCC/NAIS221112
