Superheater - an overview | ScienceDirect Topics

H. Wen, in Ultra-Supercritical Coal Power Plants, 2013. 2.5.2 Superheater conditions. Superheater (SH) and reheater (RH) tubing are required to have high mean creep strength (> 100 MPa or 14.5 ksi for 100 000 h), good thermal fatigue strength, good weldability, resistance to fire-side corrosion and erosion, and resistance to steam-side oxidation.

Boiler (Steam Generator) - Coal Fired Power Plant

A boiler or Steam Generator (prime mover) is an integral device in a fossil fuel power plant used to produce steam by applying heat energy to water. A boiler incorporates a furnace in order to burn the fossil fuel (coal, gas, waste etc.) and generate heat which is transferred to water to make steam.
