- W2053481567 abstract "This program is aimed at defining the chemistry and combustion kinetics necessary to optimize the sulfur capture with the ultimate applications of reducing the SO/sub 2/ and NO/sub x/ in the firing of pulverized coal. The program is separated into three tasks: (1) a study of CaS production; (2) a study of CaS oxidation; and (3) a staged combustion study of coal and CaO-treated coals. The Task 3 studies are aimed at defining the chemical and kinetic parameters governing CaS and CaSO/sub 4/ formation in staged combustion. Two combustors are being used in this task. The smaller combustor is being used to examine sulfur capture chemistry under a broad range of experimental conditions. Optimum sulfur conditions determined from the smaller unit will be applied where feasible to the larger unit to determine the effects, if any, of scaled-up operation on sulfur capture chemistry. Conditions of optimum sulfur capture will be examined in the larger unit. The single stage fuel-rich firings in the Task 3A coal-gas (methane) studies continued this quarter. Residence time effects and the possible effects of methane combustion on the sulfur retention process were examined. The Task 3B study of the sulfur capture chemistry in staged combustion usingmore » the kilogram/h coal combustor was initiated this quarter. Preliminary runs with raw coal indicate the combustor is operating satisfactorily. (DMC)« less" @default.
