要看蒸汽是和循环水换热还是和脱盐水换热。如果和循环水,可以不保温。如果和脱盐水换热,要保温,脱盐水取热后还有其他用途。

本帖最后由 清城君 于 2020-3-10 09:34 编辑 需不需要保温要看换热的目的。楼上提到脱盐水需要循环水不需要,应该是基于工厂实际。一般来说循环水只是给介质降温,循环水越冷越好,所以不保温进行散热,换热后的循环水回凉水塔所以温度越低越好。脱盐水可能是去锅炉补水的,换热后温度提升一点有利于回收热量,做保温减少热量损失

保温通常考虑两个方面,一是绝热,防止和减少热量(冷量)的损失,二是人和环境的防护,防止烫伤或对环境造成不利的影响。你看呢?

您好⊙▽⊙,脱盐水为什么需要保温
