Superheater&Reheater, Custom Component For Boiler

A superheater is a component that heats saturated steam in an industrial boiler, turning it into superheated steam. Our superheater guarantees that the superheated steam temperature will fluctuate to within an allowable range (normally varies from 540°C to 500°C)when the boiler is over loaded.

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

1. 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.
2. Application:
3. Steam super heater is consisted of dense tube coils and is placed in the flue under the tempearture 450ºC-1000ºC.
4. For power plant boiler capacity over 10Mpa, platen and coiled superheater are usually adopted.
