  • One dry bottom, pulverized coal-fired boiler, identified as Boiler No. 1, installed in 1967, with a nominal heat input capacity of 4,802 million Btu per hour (MMBtu/hr), with an electrostatic precipitator (ESP) for control of particulate matter, a flue gas desulfurization (FGD) system for control of SO2, and exhausting to stack 1. Boiler No. 1 was configured with a low NOX burner in 1993. Selective Catalytic Reduction (SCR) to control NOx, Dry Sorbent Injection System to control SO3, Activated Carbon Injection System to assist in control of Hg emissions are scheduled to be installed by 2015.
