In order to improve combustion efficiency and to reduce pollutant emissions, it is necessary to be able to describe all the stages of combustion of pulverized fuel. In this paper details are outlined on ways in which this can be achieved and particular attention is given to the case of coming coal with natural gas.

A model of the ignition of a polydisperse cloud of brown coal particles, in a known gas environment, is presented and used to predict the behavior of the particles in a burner jet of a utility boiler. The model allows for drying, devolatilization, and char combustion of the particles. It is assumed
Results of experiments to determine the extent of heterogeneous combustion in the rapid-devolatihzatton regime of fuel-rich bituminous and subbituminous coal-dust flames are reported. Major gas concentrations, gas and particle temperatures, and solids proximate and elemental compositions were measur
