Description of the source (including control equipment). Please see the attachments for source or process flow diagram:

Dunkirk Power Station is located in the city of Dunkirk, New York on the east shore of Lake Erie. The power plant has a total of four pulverized bituminous coal-fired steam generators. Unit 4 is rated at 192 MW. Generating Units 4 is a coal-fired CE Balanced Draft Fu rnace. The unit is designed to produce 1,470,000 #/hr of steam at 2,400 psig with cross compound turbines. The unit is base loaded and shares a common stack. The unit is comprised of two furnaces; a superheat furnace and a reh eat furnace. The furnaces share a common drum and are coupled with two-forced draft and two induced draft fans each. Each forced draft (FD) fan discharges to a regenerative air heater that exhausts to the secondary air ducts. The FD fan discharges, for each unit, are cross-tied. The flue gas from unit 4 enters breaching that leads to the newly installed baghouse (99% removal efficiency). Stack 3 is 310 feet high and is constructed of reinforc ed concrete with an acid resistant brick liner. The unit is equipped with a fabric filter baghouse combined with Trona injection and Activated Carbon Injection. Industr y /SCC/NAIS: 221112
