摘　　要：煤气化按煤的粒度和气化炉内的气体流速等可分为固定床、流化床、气流床3种。其中干煤粉气流床加压气化具有易大规模化、煤种适应范围广、碳转化率高等特点,近年来得到大规模的应用。详细介绍了以干煤粉为原料的Shell、Prenflo、Simens GSP和西安热工院的两段式气化技术。Coal gasification is the key technology of developing coal-based industrial chemical products,liquid fuel,IGCC,fuel cell and integrated utilization system.Pressurized entrained flow dry-feeding coal gasification has the advantages of high throughput per gasifier,wide adaptability of coal type and high carbon conversion efficiency,so it is used on a large scale.This paper detailedly introduces dry-feeding coal gasification technology,such as Shell,Prenflo,GSP and TPRI Two-stage gasification.
