The first phase of the experimental investigation in our institute on pressur-ized fluidized bed combustion(PFBC)technology is introduced,and the results of fivetests are presented.The combustion efficiencies were as high as 97% 98% when high ashcontent coal was burnt in PFBC,and the sulphur retention efficiencics were 80%-85%with the Ca/S mole ratios between 1.5-1.8.The particulate content in flue gas at the out-let of high temperature gas clean-up system was 189mg/m~3(normalized).The average di-ameter of particles was 2.5-3μm and the weight fraction of particles with diameter largerthan 10μm was not greater than 3%. 相似文献
