Advanced slagging coal combustion system ASCCS
TRW has developed an advanced slagging coal combustor for the conversion to coal of coal-, oil-, and gas-fired boilers, furnaces, kilns, and other heat utilization equipment. A partially developed, slagging combustor was characterized at a thermal power level of 10 MM Btu/hr with Eastern and Western pulverized coals, and an Eastern coal water mixture. Scaling and Performance verification testing was performed on a full scale 50 MM Btu/hr combustor. The TRW 50 MM Btu/hr combustor was then mated with a TRW supplied boiler simulator to investigate combustor interaction effects with downstream heat utilization equipment. This final technical project report presents the results of a three year effort to develop a data base for coal conversions. Significant contributions have been made in coal mineral matter removal (90%+), NO{sub x} control through combined fuel and oxidizer staging (to 250 ppMv), and characterization of the combustor particulate effluent (4 micron mean diameter, 5% above 10 microns). Fair SO{sub x} control was achieved at the 30% to 40% reduction level. The ability to use coal water mixtures as a fuel delivery option was met with limited success. 72 figs., 5 tabs.
