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.

Boiler Industrial SA210A1 Steel Boiler Economizer Heat Exchange Part ASME Certification Introduction The H-shaped finned tube is also known as the H-shaped fin tube, also known as the butterfly fin tube. It is to weld symmetrically two pieces of steel with an arc in the middle to form fins (ribs or butterflies), the frontal shape of which resembles the letter "H", so it is called the H-shaped finned tube. The two fins of the H-shaped fin tube are rectangular and approximately
