Professional Boiler Superheater/Reheater Assemble In Steam Power Plant
Production Of Superheater And Reheater
The Steam Superheater is a coil type heat exchanger which is used to produce superheated steam or to convert the wet steam to dry steam, generated by a boiler. It is different from a boiler in a way that, boiler utilizes both sensible heat as well as latent heat to convert water into steam while superheater utilizes only sensible heat to superheat the steam in order to increase its enthalpy.
The platen superheater is composed of steel pipe with outer diameter of 32 ~ 42mm and header, which is generally suspended at the upper part of furnace or furnace outlet. The number of tubes in each screen is generally 15 ~ 30, which is determined according to the required steam flow rate
The outside diameter of the pipe is generally 30-60mm. The convection superheater is the most commonly used, and the serpentine tube type is adopted. It has a relatively dense tube group, which is arranged in the flue of 450-1000 ℃ flue gas temperature, and is subject to the transverse and longitudinal erosion of flue gas. The flue gas mainly transfers heat to the pipe by convection, and some of it absorbs heat by radiation

ADVANTAGES Of Superheater And Reheater
1. The economizer is to heat the boiler feed water (softened water) to raise the feed water temperature, instead of heating the boiler water.Absorbing the waste heat of flue gas to heat the boiler, reducing the heat loss, improving the efficiency of the boiler and saving coal accordingly.
2. The economizer shall install the safety valve and temperature gauge separately. In case of water shortage accident of the boiler, the bypass waterway of the economizer shall be opened immediately and the inlet and outlet of the economizer shall be closed.
3. The feed water is heated in the economizer before entering the evaporative heating surface to reduce the heat absorption of water in the evaporative heating surface, which is equivalent to replacing part of the evaporative heating surface with the economizer.
4. The heating surface of the economizer is much cheaper than that of the evaporating heating surface.
