The US Department of Energy (DOE), Morgantown Energy Technology Center (METC) is sponsoring research on advanced methods for removing contaminants from the hot, fuel gas streams of coal-fired combustion or gasification plants. Contaminants present in all coals such as ash particles, compounds of sulfur and nitrogen, and alkali metals must be controlled because they are environmental problems, are detrimental to advanced generation power equipment, or both. Significant advances have been made in the high-temperature control of these contaminants. One of the most promising advanced power-generating systems uses hot gas cleanup in an integrated, gasification combined-cycle (IGCC) concept to control coal contaminants. This report discusses the status and significant accomplishments of hot gas cleanup research in support of this advanced power generation system. The objective of the DOE hot gas cleanup program is to develop the technology to economically remove hot gas-stream contaminants. The projects that comprise the program are mainly aimed at gas streams generated at pressures greater than 6 atmospheres and temperatures greater than 1000/sup 0/F. These elevated pressures and temperatures are typical of emerging technologies such as IGCC and gasifier/molten-carbonate fuel-cell (MCFC) power plants, direct-fired coal turbines, and pressurized fluidized-bed combustors. Control and removal of the contaminants is either a technical limitation or a major cost associated with these advanced systems. 113 refs., 18 figs., 4 tabs.
