Heat Efficiency Heat Exchange Boiler Parts Superheater And Reheaters For Powe Station,ISO/ASME Certification
Product Introduce of Boiler Superheater and Reheater
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.
Reheater
Power plant furnaces may have a reheater section containing tubes heated by hot flue gases outside the tubes. Exhaust steam from the high-pressure turbine is passed through these heated tubes to collect more energy before driving the intermediate and then low-pressure turbines.
Product Functions of Boiler Superheater and Reheater
Superheater
1. The dry saturated steam drum to further make the superheated steam heating. When the soda coexist, the soda heating the mixture, add heat can only be used to make soda water evaporate into steam in the mixture, and cannot make steam temperature of superheated steam. To get to the superheated steam, the commonly used method is to steam separated from the mixture of soda, for its further heating, accomplish this task components become the superheater.
2. reduce the temperature of flue gas, recover the heat in the flue gas, improve boiler efficiency.
Reheater
1.improve the thermal efficiency of the thermal cycle.
2.improve the dryness of steam exhaust, reduce steam consumption, and reduce the erosion of moisture in steam on the last few stages of turbine blades.
3.improve the efficiency of steam turbine.
4.further absorb the heat of boiler flue gas, reduce the smoke exhaust temperature.

Type Advantages Disadvantages Supporting Method
Pendant-type
1.Firm structural support
2. Flow blockage by condensed steam
3. Needs slow restart to purge the water that accumulates in the bottom. supported from above
Inverted-type
1.Proper drainage of the condensed steam
2. Lack the structural rigidity, especially in high speed gas flow Supported from below
Horizontal -type
1. Proper drainage
2. Good structural rigidity.
They do not view the flam directly so they are mainly from the convective type Usually supported in the vertical gas ducts parallel to the main furnace.
Design Structure
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.
