Superheater and economizer

WebJul 7, 2024 · 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. What is the use of economiser in chiller? WebFor this reason, the economizer is integrated into the overall design, normally between the convective super-heater and the air heater if fitted. In shell boilers with a working pressure of between 7 and 17 bar the temperature of the mass of water in the boiler is typically in the range of 170–210°C.
