A boiler is an appliance designed to heat water and produce energy. The heat is applied to water in an enclosed container before being distributed throughout the system. The major difference between a low-pressure and a high-pressure boiler is the amount of pressure per square inch and pounds per square inch gauge that the boiler produces.

Boiler pressure is the key factor for determining the requirement of a CPU system (see Figure II/3.6.6-1). For the steam generator plant with low steam pressure (below 40 kg/cm 2), the requirement of a condensate polishing unit is usually avoided. Hard scale formation and boiler metal corrosion can easily be prevented through feedwater

2016-3-22 · the space is enclosed, as in a pressure cooker or a boiler, this increases the pressure. If the pres-sure is increased, then it is more difficult for the water molecules to jump into the gas, the steam, and take up more space, and some go slow enough to be captured again into the water. Therefore, for every pressure there is a tem-
2019-12-13 · Also, higher steam pressure will be possible than with saturated steam, enabling the steam to carry more energy. Although superheating adds more energy to the steam in the form of heat there is no effect on pressure, which is determined by the rate at which steam is drawn from the boiler and the pressure settings of the safety valves.
