[Experimental investigation on sulfur emission properties of micro-pulverized coal].
Micro-pulverized coal(0-20 microns) combustion is a new kind of pulverized coal combustion technology. Four Heshan sulfur coal samples with different mean particles diameter were combusted, using a TGA-FTIR made in Germany. Micro-pulverized coal self-desulfurization and adding CaO desulfurization characteristics were investigated. Experimental result proved that micro-pulverized coal SO2 emission was less than coarse particles, and with the same Ca/S molar ratio 3 micro-pulverized coal can obtain higher sulfur capture efficiency. Its unique desulfurization property provide a new idea path for reduce sulfur releasing from pulverized coal combustion.
