| Abstract: | This paper presented a mathematical simulation model which describes the combustion system of circulating fluidized bed (CFB) boilor. The lumped parameter modle was used for the model. Considering the flow, combustion and heat transfer of the CFB boiler, the dynamic CFB boiler model was developed by dividing the boiler into a series of chambers. The dynamic mass and energy balance equations were established for different chambers. The simulation model was based on a 450t/h CFB boiler that was the largest capacity CFB boiler in China. The simulation result indicated that the model could properly reflect the dynamic characteristics of the CFB boiler which can not only be used for training simulators, but also for optimum design and calculation. |
