Optimum parameters of the air gasification of coals in a circulating fluidized-bed gas generator with a stagnant layer

Abstract

Experiments on the air gasification of coal in a circulating fluidized-bed gas generator with a stagnant layer are described. The results of the experiments are consistent with simulation data. Based on a gas generator model, optimum process parameters—temperatures in gasification and combustion chambers, chemical efficiency, and coal fraction supplied to the gasification chamber—were found.
