Comprehensive Report to Congress Clean Coal Technology Program: Healy Clean Coal Project

OSTI ID:6146380

In September 1988, Congress provided $575 million to conduct cost-shared Clean Coal Technology (CCT) projects to demonstrate technologies that are capable of retrofitting or repowering existing facilities. One of the 13 projects selected for funding is the Healy Clean Coal Project proposed by the Alaska Industrial Development and Export Authority (AIDEA). This project will demonstrate the combined removal of SO{sub 2}, NO{sub x}, and particulates from a new, 50 megawatt electric (MWe) coal-fired power plant using both innovative combustion and flue gas cleanup techniques. Coal provided by the Usibelli Coal Mine, adjacent to the project site, will be pulverized and burned at the new facility to generate high-pressure steam. The high-pressure steam will be supplied to a steam turbine generator to produce electricity. Emissions of SO{sub 2} and NO{sub x} from the plant will be controlled using TRW's entrained combustor with limestone injection in conjunction with a boiler designed by Foster Wheeler. Further SO{sub 2} and particulate removal will be accomplished using the Activated Recycle Spray Dryer Absorber System developed by Joy Technologies, Inc. The innovative concept to be demonstrated is the reuse of unreacted lime, which contains minimal fly ash, in the second-stage SO{sub 2} removal. 6 figs.
