Flow characteristics of mixed particles with a simulated cold state in moving bed reactor
文献摘要：
The funnel flow of high-temperature circulating ash and coal in moving bed with height restrictions directly influences the efficiency of coal pyrolysis and scale-up design of reactor.It is one of the technical bottlenecks in the use of moving bed.In order to provide data support for the particle flow and pyrolysis model close to the actual working conditions in the future,this study describes the flow characteristics of solid-solid mixed particles in a cold two-dimensional moving bed.The results indicate that flow char-acteristics of mixed particles in the quartz sand-coal system are better than those in the cold circulating ash-coal system.The optimized conditions were obtained,the insert half angle is 20° and a heat carrier to coal ratio of 6:1.As the mixture progressed downstream,secondary separation of the heat carrier and coal become apparent.Furthermore,mixture residence time has been investigated to explore the relationship between regional residence time and to predict accurately the actual pyrolysis progress in pyrolyzer.
