如题,1.0~1.2MPa饱和蒸汽可否适用于汽轮发电机组?目前有一个企业高温尾气排放比较头疼,如上一个余热锅炉回收烟气余热可产20t/h饱和蒸汽,蒸汽压力为1.0~1.2MPa。 有以下疑问: 1、这种蒸汽压力等级下,锅炉水处理是否执行电力标准中的(蒸汽压力为3.8MPa以上)的水质要求标准? 2、是否有成熟可靠的低压饱和蒸汽驱动的汽轮发电机组? 3、如果有成熟的低压饱和蒸汽汽轮发电机组,那么,汽轮机是否具备凝抽能力?因该项目还承担集中供热任务。供热蒸汽参数为0.8MPa饱和蒸汽。 在线急等!

饱和蒸汽驱动的汽轮发电机组在平时的电厂和化工厂没见过,一般核电用的是饱和蒸汽驱动;蒸汽压力从1.0~1.2MPa降低到0.8MPa这个压差也比较少,发电量也不会太多,估计在这个发电过程中会产生凝水,对汽轮机的叶片的也会造成比较大的影响,我感觉最好就是加个减压阀,直接降压外供供热。

1.2到0.4可以,就是蒸汽耗量多。全场蒸汽平衡满足的话不会有问题

这种饱和蒸汽发电没问题的,我们做了几个低压饱和蒸汽发电项目了。项目还在吗
