目前 ,高温、高压循环流化床锅炉高温过热器都采用常规布置方式 ,高温过热器上部受热面的材料必须采用SA2 13-T9l,它价格昂贵、加工工艺复杂 ,使高温过热器的造价较高。为此 ,提出了高温过热器的优化布置方案 ,此方案比常规布置方案更经济 ,使高温过热器受热面价格仅为常规布置方案的 80 %。因此 ,优化布置方案应在高温、高压循环流化床锅炉高温过热器布置中推广使用。
At present, the high temperature, high pressure circulating fluidized bed boiler high temperature superheater are used conventional arrangement, the material of the upper heating surface of the high temperature superheater must be SA2 13-T9l, it is expensive, complex processing technology, high temperature superheater cost . Therefore, the optimal arrangement scheme of high temperature superheater is proposed, which is more economical than the conventional arrangement scheme, so that the heating surface price of high temperature superheater is only 80% of the conventional arrangement scheme. Therefore, the optimized layout scheme should be popularized in the arrangement of high temperature and high pressure circulating fluidized bed boiler high temperature superheater.
