Steam Boiler Pressure - InspectAPedia
In the current example, reducing boiler pressure from 130 psig to 80 psig reduces the sensible heat in the boiler water from 328 Btu/lb to 294 Btu/lb. Assuming a blowdown rate of 4%, the savings is approximately 0.1% of initial fuel input. High Pressure Steam Piping Heat Loss Heat loss from steam and condensate piping takes place in two stages.
