Product Description of Boiler Superheater
For power plant boiler, it is a crutial way to increase thermal economy of thermal power station by improving parameter of superheated steam. The increase of superheated steam parameters are limited by metal materials. The design of superheaters must make sure that the temperature of outer wall of heating surface pipes is lower than allowable temperature of oxidation resistance of steel, and meanwhile make sure its mechanical strength. with the development of metal material used in boilers, pwoer station boilers in our country already generally apply high pressure, high temperature(9.8MPa, 540 degrees) and superhigh pressure parameters(13.7 MPa, 540 and 555 degrees), and have developed subcritical pressure parameters(16.7MPa, 540 and 555 degrees). Now lots of boilers apply supercritical pressure parameters(24.5MPa, 540-570 degrees), and even very few units apply higher pressure and temperture parameters.
Superheater is the part that heats the steam from the saturation temperature to the superheater by the boiler. It is also called the superheater.Superheater can be divided into convection type, radiant type and semi-radiant type according to heat transfer mode;According to the characteristics of the structure, it can be divided into serpentine tube type, screen type, wall type and wall type.They all consist of a number of parallel pipes and inlet and outlet manifold.
Functions of Boiler Superheater
1.Superheater is the saturated steam heating into a certain temperature of superheat steam equipment.
2. After the saturated steam is heated into superheated steam, the working capacity of steam in the steam turbine is improved, that is, the useful enthalpy of steam in the steam turbine is increased, thus improving the cycle efficiency of the heat engine.
3. In addition, the adoption of hot steam can also reduce the exhaust humidity of the steam turbine and avoid the corrosion of the turbine blade, which creates favorable conditions for the further reduction of exhaust pressure and safe operation of the steam turbine.
Design structure of Boiler Superheater
1. heating saturated steam, temperature up to 900 degree C.
2. high efficiency, >90%.
3. high speed heating.
4. design with stainless steel.
5. long design service life, 15 years.
