Product Description
High Integrity Superheater And Reheater Tubular Heat Exchangers Cooling Coils
Product Function
For boilers in large power stations, superheaters and reheaters are necessary parts, to a large extend, they have influnced the safety and economy of boilers. Superheaters are the heating surfaces which heat the main steam from the surnatured temperature to the rated superheated temperature, and the reheaters are the heating surfaces which heat the exaust from the steam turbine high pressure cylinder to a certain temperature.When running conditions like boiler loads, coal types change, it is to adjust them to make sure the outlet temperature at the rated level of -10-+5 degrees.
For large boilers in power stations, superheaters and reheaters account for a big proportion in the total heating surfaces, they are to be arranged in the areas where smoke is with higher temperature. To improve the efficiency of thermal circulation in power stations, it is needed to improve the original parameters f steam gradually, the increase of steam pressure requires the corresponding increase of temperature for superheated steam, or the humidity of large stage exhaust of steam turbine will be too high, which will influence its safety. Thus, the steam flowing through superheaters and reheaters are high temperature steam, their heat transfer performance is quite bad, which determines that tube wall temperatures of superheaters and reheaters are high.
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.

High Pressure Power Boiler Heating Surface Membrane Wall Argon Arc Welding For Biomass Boiler
High Pressure Power Boiler Heating Surface Membrane Wall Argon Arc Welding For Biomass Boiler Product Introduction Water wall panels with pins usually laid vertically on the inner wall of the furnace wall, it is mainly used to absorb the radiant heat emitted by the flame and high-temperature flue gas in the furnace.It is the main type of evaporating heating surface of all kinds of modern boilers and the basic component of boiler water circulation loop.Because of both cooling
High Frequency Welding H Fin Tube Economizer For Power Plant Boiler ASME
High Frequency Welding H Fin Tube Economizer For Power Plant Boiler ASME Product Description The boiler economizer is a device used to recover waste heat in industrial boilers, usually located at the tail of the flue of the boiler, which increases the feed water temperature and reduces fuel consumption by absorbing the heat of the flue gas, so as to achieve the effect of energy saving and emission reduction. But at the same time, as an environmental protection equipment, the

Boiler Industrial SA210A1 Steel Boiler Economizer Heat Exchange Part ASME Certification
Boiler Industrial SA210A1 Steel Boiler Economizer Heat Exchange Part ASME Certification Introduction The H-shaped finned tube is also known as the H-shaped fin tube, also known as the butterfly fin tube. It is to weld symmetrically two pieces of steel with an arc in the middle to form fins (ribs or butterflies), the frontal shape of which resembles the letter "H", so it is called the H-shaped finned tube. The two fins of the H-shaped fin tube are rectangular and approximately
