Reheaters and Superheaters - Vallourec

2019-7-23 · Reheaters and superheaters are a set of tubes located in the boiler. Steam from the water walls passes to the superheaters where it is heated above its saturation temperature until the maximum required operating temperature is achieved. The superheated steam then flows through the main steam piping to the high-pressure turbine.

Superheater - Wikipedia

2019-7-18 · A superheater is a device used to convert saturated steam or wet steam into superheated steam or dry steam. Superheated steam is used in steam turbines for electricity generation, steam engines, and in processes such as steam reforming. There are three types of superheaters: radiant, convection, and separately fired. A superheater can vary in

types of superheater boiler in 2018

Types of Superheater Boiler: The superheater is a subcritical boiler component that serves to heat the saturated steam, at constant working pressure, so it becomes superheated steam. At the beginning of the 20th century, some engineering experts patented the design of different superheater. The below are the different types of superheater
