Steam Superheaters

2019-6-7 · Superheaters are essentially a bank of tubes, in the exhaust gas duct after the boiler, used to heat the steam above the saturation temperature. The saturated steam enters the inlet header from piping connected to the steam drum. In a superheater, the saturated steam flows from the saturated header through the superheater elements into the superheater outlet header.

Superheater - ipfs.io

A superheater is a device used to convert saturated steam or wet steam into superheated steam or dry steam. Superheaters are used in steam engines or in processes, such as steam reforming.There are three types of superheaters: radiant, convection, and separately fired. A superheater can vary in size from a few tens of feet to several hundred feet (a few metres to some hundred metres).

Boiler (power generation) - Wikipedia

2019-9-7 · 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 steam generator.
