What keeps a superheater from being damaged by heat before

Answer (1 of 3): Before boiler startup, a vent valve on the exit of the superheater is opened to the atmosphere. (The superheater outlet is also opened to the steam header, with backflow prevented by the non-return valve in the line.) The open vent ensures that steam will vaporize in the boiler a

What is a Superheater? (with pictures) - Info Bloom

A superheater may be found in steam boilers. A superheater is a device found in steam boilers that is used to convert wet, saturated steam into dry steam. Superheaters are a very beneficial part of the steam cycle, because dry steam contains more thermal energy and increases the overall efficiency of the cycle.

(PDF) Design of Superheater for 210 MW Thermal Power Plant

Superheater is a component of a steam-generating unit in which steam, after it has left the boiler drum, is heated above its saturation temperature. The amount of superheat added to the steam is influenced by the location, arrangement, and amount of superheater surface installed, as well as the rating of the boiler.

Thermodynamics Boilers - Roy Mech

To superheat the steam it is fed from the boiler drum via banks of steam tubes (superheater) through the region of the combustion chamber where the hottest gases are flowing. The superheater only slightly increased the boiler efficiency but there is a significant benefit in the turbine efficiency because there is a reduced steam consumption in

Steam Superheaters - Marine steam boilers and boiler

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.

Overheating conditions may develop during times of low-load operation when adequate distribution of saturated steam across the tube bank at the inlet header has not been achieved. Soluble-salt deposits may form at a superheater tube inlet as a result of excessive entrainment of boiler water solids with the steam. This can result in restricted flow.
