STABILITY OF CALCIUM SULFATE AT THE GASIFICATION OF SOLID FUEL IN THE FILTRATION MODE

The regularities of SO2 release from calcium sulfate during the gasification of solid fuel in the filtration combustion mode have been studied. The maximum amounts of SO2 released into the gas phase under real conditions of a laboratory vertical shaft reactor have been estimated. It has been shown that the most important factors determining the stability of CaSO4 are the process temperature and the amount of silicon dioxide in the inorganic part of the solid fuel.
