- See superheating for the physics process.
is a device used to convert saturated steam
or wet steam into dry steam
used for power generation or processes. There are three types of superheaters namely: radiant, convection, and separately fired. A superheater can vary in size from a few tens of feet to several hundred feet (a few metres or some hundred metres).
A radiant superheater is placed directly in the combustion chamber.
A convection superheater is located in the path of the hot gases.
A separately fired superheater, as its name implies, is totally separated from the boiler.
is a device in a steam engine
, when considering locomotives, that heats the steam generated by the boiler
again, increasing its thermal energy
and decreasing the likelihood that it will condense
inside the engine . Superheaters increase the efficiency of the steam engine, and were widely adopted. Steam which has been superheated is logically known as superheated steam
; non-superheated steam is called saturated steam
or wet steam
. Superheaters were applied to steam locomotives
in quantity from the early 20th century, to most steam vehicles, and to stationary steam engines. This equipment is still an integral part of power generating stations throughout the world.
In steam locomotive
