Abstract
—Single particle combustion experiments were carried out with 50-100 μm char particles derived from one lignite and one HVA bituminous coal. Reactor wall temperatures in the range 1050 K to 1450 K and oxygen partial pressures of 0.21 and 0.5 were used. The complete temperature-time histories of individual burning particles were measured using two-color optical pyrometry techniques. Apparent combustion rate parameters of the chars were then estimated using a model of single particle combustion and taking into account the random particle-to-particle property variation.Keywords
