摘要：

The bed fuel inventory is one of the key variables in the fluidized bed combustion process when describing the dynamic behaviour of combustors burning fuels like coal or graphite. Many of the essential features of fluidized bed combustor responses can be simulated with the dynamic model presented. The model consists of differential equations describing the dynamic behaviour of the furnace and steady-state calculations for the burning of char particles. The simulations show good agreement when compared to process measurements from a commercial-sized coal combustor.
