Aug 16 2017 · 1) IBR Gross Output: This is the amount of heat energy actually transferred to the water during steady state operation. The assumption of this particular rating is that any heat lost through the boiler jacket is wasted and does not contribute to the building heating load. This rating assumes the boiler is in an unheated space.

How to Boiler Work...? - alwepo

May 16 2021 · The boiling point of water is normally 100 C which is the temperature at which water turns into steam at normal pressure (1 bar). Thus the steam produced from boiling the water is also 100 C. If a boiler wants to produce hotter steam it is necessary to increase the pressure so that the boiling point of water increases (see graphic below).
