SULFUR ORES TURNING TO GOOD VALUE - VOLCA NIC SULFUR BURNING KINETICS

The vapourization step in inert atmosphere of sulphur from individual particles ore (8-12 mm), at temperatures higher than the melting tempe rature (444.6 degrees C) was experimentally studied. For 10 mm particl e diameter the specific vapourization rate is equal to the rate for th e pure sulfur. The vapourization in air and burning rates of sulfur we re experimentally determined for spherical particles (8-12 mm), togeth er with sulphur yield and total combustion time. In the specified oper ation conditions the sulphur vaporization rate is the limiting factor in the combustion process.
