A five year feasibility study was conducted using process modeling to design new fuels that could inherently reduce nitric oxides, sulfur dioxide and mercury emissions in power generation. The commercial station chosen for the study was a northeastern utility in Homer City with a history of emission difficulties. Heat data for the utility's unit 3 was available from diagnostic work done at this station back in the early 1980s. Unit 3 has a pulverized coal (with CE Raymond Mills) balance draft steam generator with single stage reheat rated at 4,280,000 lb steam per hour. The Turbine is a 692 MW four valve unit operating in variable pressure mode. The unit utilizes two steam driven boiler feed pumps. |
