A well-designed CFB combustor can burn coal with high efficiency and within acceptable levels of gaseous emission. In this study, the combustion efficiency of CFB combustor based on the losses has been defined and effects of operational parameters on combustion efficiency have been investigated by a dynamic 2D model which has been developed in our previous studies. Investigations on combustion ...
