摘　　要：在增压流化床燃烧 (PFBC)中试电站 ,气力输送技术是关键性技术 ,它关系到以燃料是否能连续稳定送入增压流化床内 ,保证增压流化床正常稳定燃烧。考察了在背压为 0 .6 MPa(PFBC中试电站流化床压力 )下 ,固气比和喷射器 (无二次喷嘴 )Pneumatic transport technology is a key technology in PFBC experimental power-station,which is related to whether the fuel can be sent into the pressured fluidized bed continuously and steadily,and ensures the fuel to combust normally and steadily in the pressured fluidized bed.This paper mainly studies the influences of the ratio of solid to gas and the position of gas nozzle in the injector (without secondary nozzle) on the stability of pneumatic conveying at a terminal pressure of 0.6 MPa.

关 键 词：增压流化床 气力输送 固气比
