Second-generation pressurized fluidized bed (PFB) combustion plant: Conceptual design and optimization of a second-generation PFB combustion plant, Phase 1, Task 1
This three-volume report presents a conceptual design of a coal-fired second-generation pressurized fluidized bed (PFB) combustion plant and identifies its sensitivity to varying operating conditions and economic factors. Depending upon the conditions selected, the plant can achieve a 45-percent efficiency (based on the higher heating value of the coal used as fuel) and 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 reaches these performance levels by integrating a coal pyrolyzer/carbonizer with a circulating pressurized fluidized bed combustor (CPFBC). Char produced by the carbonizer is burned in the CPFBC and the low-Btu fuel gas produced by the carbonizer is burned in a topping combustor to heat the CPFBC exhaust gas to 2100{degree}F and higher before it enters the 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 PFB plants (gas turbine inlet temperature {le}1600{degree}F) protect the gas turbine from corrosion, erosion, and deposition. 120 figs., 115 tabs.
