Evaluation of gasification and gas-cleanup processes for use in molten-carbonate fuel-cell power plants. Quarterly technical progress report No. 3, October-December 1981
The Task A Topical Report, which provides process information definition of coal gasification and coal gas cleanup systems, is in the process of being printed. The Task B interim report is complete and is being typed for issue in January. This report provides a choice of the gasifier/cleanup system combinations most suitable for MCFC-based power plant application. Included are hot gas cleanup, air-blown, oxygen-blown and molten salt based coal gas supply systems which consider, where applicable, a Texaco and a British Gas Council/Lurgi Slagging system for comparison with previously published EPRI, UTC and GE work. This Quarterly Technical Progress report (No. 3) provides a complete review of particulate tolerance of the fuel (anode) side of MCFC units. This evaluation, which was formally authorized by DOE/METC in October, provides an assessment of deposition for power plant size molten carbonate fuel cells and describes mechanisms affecting particle transfer in fuel cells. The assessment concludes that gas cleanup to remove virtually all particles larger than one micron in diameter is expected to prevent, or at least minimize to a negligibly low level, deposition of particulate material on the anode. However, cathode particulate deposition in molten carbonate fuel cells should be evaluated in the future, since cathodes are more likely to experience deposition even though cathode channel particle concentrations can be much lower than anode channel concentrations. Cathodes are more susceptible to deposition than anodes due to a net mass flow of gases into cathode pores compared to a net mass flow of gases out from anode pores.
