Make-up water for steam boiler — Heating Help: The

Make-up water for steam boiler This is probably a real dumb question but I cant seem to find the answer. Why is cold water used for make-up water on a steam boiler? Why not hot water? I would think hot water would be better because a lot of the soilds have already dropped out of it in the water heater meaning less sludge in the boiler. 0.

Boiler feedwater - Wikipedia

2020-12-24 · Boiler feedwater is an essential part of boiler operations. The feed water is put into the steam drum from a feed pump. In the steam drum the feed water is then turned into steam from the heat. After the steam is used it is then dumped to the main condenser. From the condenser it is then pumped to the deaerated feed tank. From this tank it
