Heat Efficiency Improving Boiler Parts Superheater Coils ASME Standard For Power Station
Product Description:
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.
| 1 | Material composition | Carbon steel, alloy steel or heat-resistant steel, collection boxes and other supporting material. Tubes are customized types of specifications. |
| 2 | Design pattern | Vertical or horizontal layout. |
| 3 | Advantages | Beautiful appearance, size, accuracy, first-class bending and welding technology, first-class detection equipment. |
Type Advantages Disadvantages Supporting method:
Pendant-type 1.Firm structural support
1. Flow blockage by condensed steam
2. Needs slow restart to purge the water that accumulates in the bottom. supported from above
Inverted-type 1.Proper drainage of the condensed steam
1. 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.
