Second-generation pressurized fluidized bed combustion plant research and development needs, Phase 1, Task 2: Topical report
Technical Report
·
OSTI ID:5784173
This report identifies, classifies, and ranks 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 can achieve a cost of electricity at least 20-percent lower than that of a conventional pulverized-coal-fired plant with wet-lime-stone 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 at /le/1600/degree/F. Components being developed for first-generation pressurized fluidized bed combustion plants (gas turbine inlet temperature /le/1600/degree/F) protect the gas turbine from corrosion, erosion, and deposition. 14 refs., 15 figs., 6 tabs.
