摘要
In this paper a mathematical model to describe a Circulating Atmospheric Fluidised Bed Combustor (CAFBC) is presented. For the fast section of the bed, momentum and energy balance equations are used to predict temperature and velocity profiles for gas and particles. The model performs mass balances for the chemical gas species (O2, H2O, CO2, CO and SO2) With consideration on the last being given for retention by limestone particles. A bubbling bed model is considered to simulate the bottom of the CAFBC. The model is applied to typical conditions of a boiler and the results show the expected trends.
