Product Function
1.The function of the superheater in the thermal power plant is to remove the last traces of moisture ( 1 to 2%) from the saturated steam coming out of boiler and to increase its temperature sufficiently above saturation temperature.
2.The super-heating heating raises overall overall cycle efficiency efficiency as well as avoids too much condensation in the last stages of the turbine which avoids the blade erosion.
3.The heat of combustion gases from furnace is utilized for the removal of moisture from steam and to superheat the steam.
4.Super-heaters usually have several tube circuits in parallel with one or more return bends, connected between headers.
1.The function of the re-heaters is to resuperheat the partly expanded steam from the turbine.
This is done so that the steam remains dry as far as possible through the last stage of the turbine.
2.Location: Before or after the convective superheater in the convective zone of utility boilers. In modern high pressure boilers, reheaters are generally in two sections.
3.The primary section is placed in the convective zone and secondary section is placed just at the furnace exit hanging from the top.
4.The design consideration for reheaters are similar to those for superheaters.
5.It having same output temperatures but steam pressures are about 20-25% of those in superheaters. Hence lower grade steel alloy can be used for reheaters.
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
