摘要

Capital and operating cost estimates have been prepared for over-the-fence retrofitting of existing 500 MWe power plants to burn medium-Btu gas derived from developmental-stage, second-generation, oxygen-blown coal gasification processes. The economics of the retrofit installations, including the complete gasification system costs, have been compared to those of a reference power plant defined as a new, gas-roots, conventional coal-fired boiler facility equipped with flue gas desulfurization. The two types of power plants selected for retrofit are representative of relatively new (1) natural-gas-fired boiler plants and (2) oil-fired combined-cycle units. The reference power plant contains two 500 MWe coal-fired units typical of current new installations. The two oxygen-blown coal gasification systems evaluated for each retrofit were the Texaco process and the Combustion Engineering process. Neither of these gasification processes has been demonstrated at the commercial scale used in this study. Each coal gasification system was treated as a completely separate, self-contained facility supplying medium-Btu fuel gas to an adjacent existing power plant. With coal priced at $1 per million Btu, busbar power costs ranged from 37.6 to 42.3 mills per kilowatt-hour for the retrofit plants and were 38.5 mills per kilowatt-hour for the reference coal-fired boiler plant. It is concluded that further study of these retrofit options is warranted. Actual implementation of any of the retrofit designs described in this study must await commercial demonstration of the particular coal gasification process. (ERA citation 05:005691)
