High Pressure Boilers: Features and Advantages ~ ME Mechanical

Oct 27, 2016· 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.

Why are all high pressure boilers water tubes? - Quora

Mar 27, 2018· Answer Wiki. As compared to fire tube Boilers, water tube Boilers are used for high pressure application because The heat transfer area is more in water tube boilers as Water flows in tube and flue gasses are around the tube, results more heat exchange between water and flue gasses . Just like shell and tube system.

Difference Between Low- and High-Pressure Boilers | Hunker

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. Low-pressure boilers will heat a school or office building.

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.

Boiler Types and Classifications - Wiki - odesie by Tech

There are two general types of boilers: ''fire-tube'' and ''water-tube''. Boilers are classified as "high-pressure" or "low-pressure" and "steam boiler" or "hot water boiler.". Boilers that operate higher than 15 psig are called "high-pressure" boilers. A hot water boiler, strictly speaking, is not a boiler.
