原煤可磨性对气流床粉煤气化混配煤煤粉均匀程度的影响
Effect of raw coal grindab il ty on the unifor mity of pulverized blended coal for entrained-flow pulverized coal gasification
摘要
Abstract
Two pulverized coals take n from an entrained-flow plu verized coal gasification unit at different operating periods were adopted as ht e experime ntal materials, which were divided into two groups based on the partical size to investigate the effect of ar w coal grinad bility on the uniformity of pulverized blended coal.The coal quality and the ash character of the subsamples were analyzed as well.The results show that the grindability of raw coal has a great influence on the partical size distribution and the uniformity of pulverized blended coal, and the partical size distribution of blended coal is mainly depended on the raw coal with a smaller grindability index .The smaller the raw coal's grindability index, the larger the particle size of the pulverized blended coal.It si therefore concluded ht at the pulev rized blended coal made from similar grindability raw coals is more uniform. Ont he othre hand, differetn grindabilities of raw coals lead to nonuniformity and segregation of the pulverized blended coal and induce an accumlu ationo f hard coal in the large particles, which will cause the reactivity of the pulverized blended coal decrease.关键词
