从目前国内在建的600MW CFB锅炉的结构上看,形似300MW裤衩腿型CFB锅炉,因此在运行工况和操作调整上二者必然有相通之处。总结了300MW裤衩腿型CFB锅炉在燃用风氧化煤、煤矸石和煤泥等恶质煤时存在的一些现象,以此来分析600MW CFB锅炉在运行调整中可能会遇到的问题,并对其结构设计提出了几点建议。
From the current domestic 600MW CFB boiler structure point of view, the shape of 300MW pants legs CFB type boiler, so the operating conditions and operational adjustments must have the same between the two. This paper summarizes some problems existing in 300MW short legged CFB boiler when it is used to burn bad coal, such as wind, coal gangue, gangue and slime, and analyzes the problems that 600MW CFB boiler may encounter in the adjustment of operation. The structural design made a few suggestions.
