Abstract
Circulating fluidized bed boiler is a core technology of clean combustion,which can use a variety of low-grade solid fuels,such as garbage,biomass,coal,etc.,to achieve efficient and low-pollution energy utilization.In order to explore a suitable coal combustion model,this paper uses the component transport model,takes boiler combustion as the background,and studies the combustion process of circulating flu-idized bed boiler through DPM model.The corresponding simplified model of the air distribution plate and the return device of the circulating fluidized bed boiler were established.The temperature field distribution and component concentration distribution of circulating fluidized bed boiler were obtained,and the effects of fuel size and excess air coefficient on the combustion status and temperature distribution of boiler were also studied.The results show the relationship between temperature distribution and position and airflow distribution in the boiler combustion process,and the discrete phase concentration distribution range and discrete phase burnout rate are affected by the excess air coefficient.关键词
