Does lower pressure mean lower steam output?
Does lower pressure mean lower steam output?
(OP)
I was wondering whether firetube boilers designed to work with a given pressure, would produce the same amount of steam if operated at lower pressures, or would suffer a derating in steam output.





RE: Does lower pressure mean lower steam output?
Steam density change is important at low pressures. By lowering the operating pressure, a larger volume of steam is generated; the pattern of circulation and heat distribution in the boiler is changed.
A down rating is expected to occur and, among other things, the resize of safety valves and other support equipment will be necessary.
RE: Does lower pressure mean lower steam output?
related not much to the pressure but by the capcity or ''fire'' input you put
in it. ifr the boiler is designed to higher pressure and you then decide to runn iot at considerable lower pressure, you may not have the header/outlet sized
for the amount of steam at the lower pressure, means too small a nozzle.
