热煤气除尘是燃煤联合循环发电系统中的一个关键技术。已建成的陶瓷管过滤热煤气除尘单元，，除尘效率高。本实验采用真实煤气和空气配尘路线，对热煤气除尘工艺及诸因素对除尘器的影响进行了全面探讨。 Hot gas dust removal is a key technology in coal-fired combined cycle power generation systems. The built-in ceramic tube filter hot gas dust removal unit has high dust removal efficiency. In this experiment, the real gas and air dust distribution routes were adopted, and the effects of the hot gas dust removal process and various factors on the dust collector were thoroughly discussed.
