What is superheater? - Instrumentation and Control Engineering

Is a tool to find out process parameters such as temperature and pressure of combustion, the temperature of steam in and out whether it is desired or not. Since steam can only be superheated when there is no water left around to evaporate, any superheated steam boiler takes steam at the boiler outlet to superheat.

Steam boilers are controlled by steam pressure. A pressure gauge turns the burner on and off to maintain a set pressure. Room thermostats open and close valves (shown in graphic to the right) on the steam radiators to regulate space temperature. The more the valves to the radiators are open, the more the burner must fire to maintain steam pressure.

Controlling TDS in the Boiler Water | Spirax Sarco

As a boiler generates steam, any impurities which are in the boiler feedwater and which do not boil off with the steam will concentrate in the boiler water. As the dissolved solids become more and more concentrated, the steam bubbles tend to become more stable, failing to burst as they reach the water surface of the boiler.
