摘要：
Experiments were conducted to study structural changes (diameter, specific surface area and density) and mode of combustion of lignite char in a fluidised bed combustion process. Analysis of data demonstrates the effect of attrition along with combustion. Internal burning at least to the extent to which burn off has been studied, does not play a significant role. Despite attrition effects, the change in diameter approximates that of an idealised shrinking sphere. Copyright © 1990 Canadian Society for Chemical Engineering
