摘　　要：对于煤粉的燃尽程度和煤粉在炉内的停留时间的研究是一个需要引起电力行业工业界和学术界着重考虑的问题。采用数值模拟的方法对炉内煤粉颗粒的行为特征进行了详细的计算 。The study on the burning-up degree of coal and the duration time of coal in the furnace is so important that needs serious consideration of industrial and academic circles of power industry. Detailed calculation on behavior characteristics of coal particles in furnace was conducted using numerical simulation method and the result showed that the method and model adopted for studying the behavior characteristics of coal particles are reasonable and feasible.
