A 180-MWe British Gas/Lurgi-based IGCC (integrated gasification combined-cycle) power plant: Feasibility study at Virginia Power and Detroit Edison: Final report
This study investigated the merits of combining the British Gas/Lurgi slagging gasifier (BGL gasifier) with an advanced gas turbine in a 180-MWe, commercial-scale IGCC power plant located at Virginia Power's Chesterfield station. The gasification plant was fed with run-of-mine Pittsburgh No. 8 coal (containing 60 percent fines) and sized to fully load one General Electric MS7001F gas turbine at 88/degree/F ambient temperature. Seventy-five percent of the total coal fines were pelletized by agglomeration prior to gasification. All recovered tars and oils were recycled to the gasifier, while the gas liquor (process wastewater) is completely incinerated. The results of the study indicate that the IGCC power plant has a very good heat rate on coal (8993 Btu/kWh at 59/degree/F and a moderate capital cost, i.e., total capital requirement, on coal ($1910/kW at 59/degree/F, with AFDC) for a commercial-scale plant in this size range. With distillate augmentation to the medium-Btu fuel gas at 59/degree/F, the capital cost drops to about $1770/kW (with AFDC). A sensitivity study compared the cost and performance of a similar IGCC power plant located at an alternate plant site owned by Detroit Edison. The capital cost for the Detroit Edison plant increased by about $200/kW, with a very slight improvement in heat rate. 16 figs., 59 tabs.
