摘　　要：煤的部分气化及气化后半焦的加压燃烧是第二代增压流化床蒸汽燃气联合循环 (PFBC -CC)发电技术的重要组成部分。半焦在压力下的燃烧特性则是目前该领域研究攻关课题之一。对半焦加压燃烧的研究进行了综述 ,阐述了压力下半焦的燃烧特性、反应特性、半焦形态。Partial Coal Gasification (PCG) and coal-char combustion play a very important role in the 2G PFBC-CC technology taken as Clean Coal Technology (CCT) in the 2 1 st century. The study on coal-char combustion characterization at elevat ed pressure is focused for its efficient combustion and utilization. The state o f the art of coal-char combustion, reactivity, formation structure, combustion dynamics, and mathematical models, were summarized in this paper.
