INFLUENCE OF MIXING ON KINETIC PROCESSES IN ENTRAINED COAL GASIFIERS

摘要

Several gasification processes under development include an entrained gasifier as one step in the process. In such cases, coal or char is contacted with a hot gas to cause particle combustion or gasification. Design and optimization of such units require an understanding of particle gasification kinetics together with insight into turbulent mixing processes of the coal-laden streams with the hot gases. This study is designed to investigate the effects of the mixing processes in entrained gasification reactors on gasification kinetics, product yield, and ultimately upon optimum system design.
