Utility / Power Station Recuperative Boiler Air Preheater Heat Preservation High Efficiency/power plant boiler
Description
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.
Function
Superheater is to increase the temperature of the steam above its saturation
point.
Reheater is basically a superheater that superheats steam exiting the
high-pressure stage of a turbine. The reheated steam is then sent
to the low-pressure stage of the turbine. By reheating steam
between high-pressure and low-pressure turbine it is possible to
increase the electrical efficiency of the power plant cycle beyond
40%.The reheat cycle is used in large power boilers since it is
feasible economically only in larger power plants.
Certification
Features
1. As the flue gas across tube, the flue gas side of the heat
capacity of exile to strengthen, under the same heat transfer
coefficient, wall temperature vertical preheater than ordinary
steel increased 10-30 Degree Celsius, the overall heat transfer
coefficient of about 20.3-24.2W;
2. Two horizontal sealing tube box, the sealed tube box structure
welded high strength, pipe damaged or the overall change can only
block, and heat-packing seal, can only replace the damaged pipe
tube, easy maintenance.
3. The tube air preheater is mainly used for boiler preheater, the
low temperature.
