最近,我们对一些国产和进口锅炉的再热器调温装置进行了调查和试验。经统计,国内约有75%的锅炉的再热器调温装置不能正常使用,特别是国产锅炉广泛采用的烟气再循环和汽—汽热交换器,绝大部分电厂均不能使用或达不到运行要求。由于对再热汽温没有合理而有效的调节手段,使得一大批机组的运行经济 Recently, we investigated and tested reheater temperature control devices for some domestic and imported boilers. According to the statistics, about 75% of domestic reheater thermostat devices can not be used normally, especially the widely used flue gas recirculation and steam-steam heat exchangers in domestic boilers. Most of the power plants can not be used or up to date To run the request. Due to the reheat temperature is not a reasonable and effective means of adjustment, making a large number of units operating economy
