Abstract

This chapter provides an overview of coal combustion of a single coal particle. First, it outlines heating and drying, ignition of volatiles, devolatilization, char combustion and fragmentation of coal particle. The results of experimental research of combustion and fragmentation of two brown coals (lignites), seven hard coals mined in Poland and Russian anthracite are then presented. The combustion and fragmentation behavior of these coals was tested in an externally-heated bench-scale bubbling fluidized-bed unit. Next, the mathematical model of primary fragmentation, including coal heating and volatile release is outlined. Finally, applications of coal combustion in industry and key clean coal technologies of the future are discussed.
