Description of the source (including control equipment). Please see the attachments for source or process flow diagram: Ghent Unit 1 is a wall-fired, utility boiler that combusts bituminous coal. The unit is equipped with an electrostatic precipitator (ESP) for particulate matter (PM) control, a flue gas desulfurization (FGD) system for SO2 control and a selective catalytic reduction (SCR) unit for NOx control. A dry sorbent injection system is used to control SO3 emissions with injection points upstream of the ESP and FGD systems. Industry/SCC/NAIS221112
