Fuel's Influence on the Bed Material Dynamic Balance in

A dynamic mass balance model is set up to analyze the influence of coal's intrinsic ash formation on dynamic balance of the bed material size distribution in CFB boiler's start-up process. The results show that the weight fraction of 150~300μm particles is more, the start-up time is less, and the same size particles are more in bed material in steady state, and the bed quality is better.
