Analysis of rice husk combustion phenomena in circulating fluidized bed

In order to study the characteristic of rice husk combustion in circulating fluidized bed(CFB),the combustion experiments are carried out.By analyzing the change of temperature and pressure,the influence of secondary air and circulation on the combustion in CFB is discussed.The experimental results indicate that secondary air can accelerate volatile combustion in dilute phase zone and raise the temperature remarkably.Furthermore,stable and continuous circulation can make temperature proportional distributing in CFB.These conclusions are beneficial for experimental research and practical operation of biomass CFB.
