Power Station CFB Boiler Boiler Superheater Fire Tube Boiler Pressure Parts
Superheater&Reheater, Custom Component For Boiler
Superheater bank is designed for steam exhausting in the boiler .It is different from a boiler in a way that, boiler utilizes both sensible heat as well as latent heat to convert water into steam while superheater utilizes only sensible heat to superheat the steam in order to increase its enthalpy.
Super heater types:
1. Radiant super heater: it is the earliest type of super heater and it is located above or behind banks of water tubes to protection them from direct flam or fire.
Parameters that increases the convection
a. Increasing the fuel-and air flow (combustion gas flow)
b. Increasing the mass flow rate of the steam
Radiation is mainly dependent on the flam temperature. as the steam flow rate increases the exit temperature become lower.
Radiant super heater
They are placed exposed to the heat source whcih requires the improvement of metal temperatures.
Radiant and convetive super heaters and reheaters are used for high temperature steam.
The accessory of high temperature radiant steam super heater in boiler
It is made up of snake-like tubes (carbon steel, alloy steel or heat-resistant steel, etc.) and collection boxes and other supporting material. Tubes generally have φ32, φ38, φ42 or other types of specifications, according to user's needs separately.
Reheaters
They are the sane as the super heaters but as their exit temperature is a little bit less than super heaters and their pressure is 20% -25% less than the super heater, they can stand less quality material alloys.
Application:
Steam super heater is consisted of dense tube coils and is placed in the flue under the tempearture 450ºC-1000ºC.
For power plant boiler capacity over 10Mpa, platen and coiled superheater are usually adopted.

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
