摘　　要：一套日处理５ｔ煤的加压流化床粉煤气化技术试验装置建成并投入试验运行。进行了５种原料的气化试验。试验采用螺旋和喷嘴两种加料方式。气化炉内的灰团聚与灰选择性分离技术相结合使气化灰渣含灰达９０％，煤气冷凝液中无焦油类物质。气化炉产生的煤气供低热值煤气燃烧试验和燃气轮机叶片磨蚀试验之用。介绍了加压流化床气化的工艺试验内容，煤种试验结果及环境特性数据。连续运行试验基本验证了该加压流化床气化系统的工艺可行性、装置可操作性、运行稳定性和操作安全性。The test facility of pressurized fluidized bed gasifier(ID 300 mm) with coal capacity of 5 tons per day has been established and put into test operation.Five kinds of feedstock have been gasified in pressurized condition(1 0 MPa～2 0 MPa).Both methods of screwing and nozzle spaying have been seperately adopted for stock feeding.The technology of ash agglomerating in bed and the selectively separating of ash lead to the ash content of up to 90%.No tar or oil is found in the gas condensate.The gas from gasifier was used for the test of low heating value gas combustion and the test of turbine blade errosion.The paper gives description of the content of equipment and process tests,the results of coal gasification properties study,and the enviornmental factors of the fluidized bed gasification.
