    2019-7-14 · 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 (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a

    Ideal Pressure for Steam Generation and Distribution

    Steam should be generated from the boiler at rated pressure for best steam quality. The specific volume of steam at higher pressures is lower and hence steam can be distributed through smaller sized steam pipes. This results in reduced radiation losses and lower capital investment. Below is a table illustrating the impact of pressure on

    A boiler is called a high-pressure boiler when it operates with a steam pressure above 80 bars. The high-pressure boilers are widely used for power generation in thermal power plants. In a high-pressure boiler, if the feed-water pressure increases, the saturation temperature of water rises and the latent heat of vaporization decreases.

    Difference Between Low- and High-Pressure Boilers | …

    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.

    Main steam is at 2,000 psia, 1,000 F, and has an enthalpy of 1474.1 Btu/lbm. The steam extraction (cold reheat) pressure is 300 psia, which equates (isentropically) to a cold reheat temperature of

    Why you can't use high-pressure steam boilers on low

    This is why you can't run a high-pressure boiler on low-pressure settings. The boiler manufacturer told the contractor about this when the contractor called to ask. The contractor thought he could get around the high-velocity problem by cutting into the boiler and welding a bigger nozzle onto the shell.
