Steam Pressure Reduction: Opportunities and Issues

Steam Pressure Reduction: Opportunities and Issues varies directly in proportion to the boilers net stack temperature (the difference between the flue gas tem-perature and combustion air temperature). When boiler pressure is lowered, a lower stack temperature results. This, in turn, causes slightly improved combustion efficiency.

By most manufacturers' standards, high-quality steam is 99.5-percent dry saturated steam. For a boiler to provide an appropriate amount of such steam safely, efficiently, and at the correct pressure, the amount of water inside of the boiler must be carefully controlled. This article will discuss problems associated with high- and low-water-level conditions, the effects of steam pressure and

What controls the Steam Pressure inside a boiler

Aug 25, 2015· As for saturated steam, it's the temperature of water/steam that matters. You can look up saturated steam pressure as a function of temperature in a "steam-table". If you suddenly use a huge amount of steam in a boiler, thereby lowering the pressure, the boiling water will boil explosively, thereby lowering the temperature accordingly.

Boiler (power generation) - Wikipedia

A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (72,000 kPa or 1290 psi) but, at pressures above this, it is more usual to speak of a steam generator.

Tips. Having said this, it is necessary to be mindful of the following when heating with saturated steam: Heating efficiency may be diminished if steam other than dry steam is used for process heating. Contrary to common perception, virtually all of the steam generated from a boiler is not dry saturated steam, but wet steam, which contains some non-vaporized water molecules.
