Abstract: A kinetic coal gasification model combining chemical equilibrium was established to evaluate various coal gasification schemes in a fluidized bed. Heterogeneous and homogeneous reactions occurred in coal pyrolysis and gasification processes were considered in this model. Model calculation results are in good agreement with the reported measurement data. The sum of squares of percentage deviation for gas composition calculation is about 10%, which implies that the established model can be used to predict the effects of various gasification schemes on process parameters, gas composition and gasification efficiency in fluidized bed coal gasification.
