Product Introduce:
Superheater
Fossil fuel power plants often have a superheater section in the
steam generating furnace.The steam passes through drying equipment
inside the steam drum on to the superheater, a set of tubes in the
furnace. Here the steam picks up more energy from hot flue gases
outside the tubing, and its temperature is now superheated above
the saturation temperature.
Description:
A part of a boiler that further heats steam from saturated
temperature to superheat temperature, also known as a steam
superheater.Most industrial boilers do not have superheaters, as
many industrial processes and facilities require only saturated
steam.Superheater is usually installed in power stations,
locomotives and Marine boilers to improve the cycle thermal
efficiency of the entire steam power plant.Using superheated steam
can reduce water content in steam exhaust of steam turbine.Depends
on the boiler superheated steam temperature pressure, evaporation,
steel and high temperature resistant performance and fuel price
comparison of steel, for power plant boiler, boiler in general is
about 450 ℃, 4 million mpa;More than 10 million mpa boiler for 540
~ 570 ℃.A handful of power station boiler also have higher
superheat steam temperature (or even up to 650 ℃).
Boiler superheater is energy recovery boiler flue gas, the boiler
steam heating can be obtained, a dry steam, to improve the boiler
thermal efficiency, but also to steam turbines to avoid water
hammer regenerator from steam turbine in the spent steam recycling
energy, heat into the boiler circulating water and regenerator,
level can be high pressure discharge of steam reheat, recovery
boiler energy of these devices are large boiler steam system of
auxiliary heating device, is beneficial to improve the energy
efficiency of the boiler system, only the superheater and reheater
is recycled flue gas energy, regenerator is recycling steam
energy.The function of superheater is to heat the saturated steam
to the superheated steam with a certain temperature to improve the
efficiency of power station
Material:
Superheater tube wall metal bears the highest temperature in the
pressure parts of the boiler. Therefore, high quality low carbon
steel and various kinds of chromium-molybdenum alloy steel must be
adopted. Sometimes austenite chromium-nickel stainless steel is
used in the highest temperature part.When the temperature of the
tube exceeds the allowable temperature limit of the material's
endurance strength, fatigue strength or surface oxidation during
operation of the boiler, the pipe burst will occur.

Superheater is a heating surface that heats saturated water vapor
under certain pressure into superheated water vapor under
corresponding pressure.
