CaO interactions in the staged combustion of coal. Second quarterly technical progress report, January 1, 1981-March 31, 1981
The CaO-FeS/sub 2/ reaction was studied as a function of temperature, reaction time, Ca/S mole ratio and particle size. All reactions were carried out under a nitrogen environment. The reactions were followed principally in terms of weight loss and SO/sub 2/ emissions. The decomposition of the pyrite produces S/sub 2/ which reacts with CaO to produce SO/sub 2/ and CaS. The extent of the reaction appears to increase monotonically between 555 and 970/sup 0/C.
