摘　　要：热煤气除尘（ＨＧＣＵ）在热煤气联合循环发电技术（ＩＧＣＣ）中具有重要地位．煤炭科学研究总院北京煤化学研究所气化室建成国内第一个烛状ＳｉＣ陶瓷过滤管（ＣＡＮＤＬＥ）热煤气除尘单元，该单元采用１００ｍｍ加压流化床气化炉产生的真实煤气进行试验，累计１００多小时的运行结果表明，ＣＡＮＤＬＥ除尘器可以在５００～６５０℃，１０～１６ＭＰａ的条件下较长时间稳定而连续运行，除尘单元出口精煤气含尘量为每标准立方米１０ｍｇ左右，总除尘效率达到９９９％以上．Hot coal gas filtration(HCGF) takes an important part in integrated gasification combined cycle (IGCC). The first CANDLE filtration test unit was built up in Beijing Research Institute of Coal Chemistry and it carries the test with the real coal gas from 100 mm fluidized bed gasifier. The test results of running for more than 100 hours showed that the filter can be used over a long period of time under the condition of 500650 and 1016 MPa, the dust content in outlet gas is about 10 milligrams in each cubic meter and filtration efficiency is more than 999%.
