循环流化床锅炉屏式过热器管屏变形的研究

The deformation study research of CFB platen supperheater

很多已经投运的循环流化床锅炉在运行中暴露出屏式过热器变形、超温、爆管的问题,存在安全隐患,严重影响了锅炉的安全、连续、稳定运行,造成运行成本增加。分析造成这些问题的原因,并提出相应的整改措施,取得了良好的效果。

Many Circulating Fluidized Bed( CFB) boilers which has been put into operationexpose problems like platen superheatertransformation and over temperature,tube-burst. Pose a safety hazard,seriously affect the boiler safe and continuous and stable operation. increaseed the operation cost. Analysis of the causes of these problems,and proposes the corresponding improvement measures,good results have been achieved.
