摘要

The aim of this study is to investigate the concentration of solid particles inside the furnace. Starting from the material circulating system and distribution of concentration of solid particles in CFBB, the model of material circulating system was established. Finally, the system was simulated in Matlab. Through analysis of the simulation results: along the direction of the furnace, the concentration of solid particles inside the furnace shows in the distribution of 'the upper part is dilute and the under part is concentrated'. Moreover, in the dense phase zone, the concentration of solid particles decreases rapidly. But in the transition zone and dilute phase zone, it decreases slowly and tends to be stable at the exit of the furnace.
