Superheater&Reheater, Custom Component For Boiler Superheater Coil
The function of Super heater in the thermal power plant is to remove the last traces of moisture from the saturated steam coming out of boiler and to increase its temperature above saturation temperature as per requirement at inlet of steam turbine.
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.
Details
| 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. |
Principle
Principle of superheater is similar to steam generating tubes of
boiler.
The hot gases at high temperature sweep over superheater tubes and
raise the temperature of steam which magnitude depends upon exit
gas temperature leaving the superheater and gas velocity.
use for heating saturated steam, steam temperature could be up to
900 degree C.
Superheater Capacity Upgrades to Increase Power Generation
Send us required technical data, such as steam capacity, presure, required temperature etc. We will design accordingly.
