To simulate combustion behaviour in a pilot-scale combustor, a laboratory-scale agitated combustor has been developed which allows burnout and combustion rates for large coal particles to be measured. Particle sizes up to 25 mm can be studied, typical of those used in fixed-bed retorts. Char burnout
The reported combustion kinetics of pulverized coal from two types of experiments are compared: the first from measured rates of burnout at particle temperatures of 900-2200K and the second from an analysis based on the minimum gas temperatures at which coal ignites, corresponding to particle temper
Changes in the particle size distribution of coal-water slurry droplets during water vaporization and early stages of combustion are investigated. Comparative studies for two hva bituminous coal slurries, one with and one without dispersants (surfactants), are conducted at high temperature (1900 K)
