Steady economic growth, aging US base load power plants and Phase 2 of the 1990 Clean Air Act Amendment, will stimulate planning for new base-load capacity. What type of plants will be considered for the next increment of base load in the US? One option that is frequently discussed is the repowering of existing power plants with advanced technology, clean fuels and state-of-the-art environmental controls. Repowerings using natural gas have been implemented where supplies of natural gas are adequate and pricing is competitive. Integrated coal gasification combined cycle (CGCC) is another repowering option with growing interest based on support from the US Department of Energy Clean Coal Technology Program demonstration plants and experience gleaned from plants in several European countries. The British Gas Lurgi (BGL) fixed-bed, slagging gasifier is a state-of-the-art technology well suited for CGCC repowering applications. It offers dramatically reduced environmental emissions, simplicity, and improved thermal efficiency. This paper discusses such repowering applications.
