Combustion characteristics of unburned pulverized coal and its reaction kinetics with CO2
The combustion characteristics of two kinds of unburned pulverized coal (UPC) made from bituminous coal and anthracite were investigated by thermogravimetric analysis under air. The reaction kinetics mechanisms between UPC and CO 2 in an isofhermal experiment in the temperature range 1000–1100°C wer...
