This report presents a Program Plan together with estimated costs and schedules for satisfying the research and development needs of coal-fired second-generation pressurized fluidized bed combustion plants. This type of plant can operate with a 45-percent efficiency (based on the higher heating value of the coal used as fuel) and achieve a cost of electricity at least 20 percent lower than that of a conventional pulverized coal-fired plant with wet-limestone flue gas desulfurization. The proposed plant concept integrates a coal pyrolyzer/carbonizer with a circulating pressurized fluidized bed combustor (CPFBC). Char produced in the carbonizer is burned in the CPFBC, and the low-Btu fuel gas produced in the carbonizer is burned in a topping combustor to heat the CPFBC exhaust gas to 2100{degree}F and higher before it enters a gas turbine. The carbonizer and CPFBC operate with lime-based sorbents for in-situ sulfur capture in {le}1600{degree}F. Components being developed for first-generation PFB combustion plants (gas turbine inlet temperature {le}1600{degree}F) protect the gas turbine from corrosion, erosion, and deposition. 28 refs., 15 figs., 3 tabs.
