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
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.

Design structure
• Superheating raises overall efficiency as well as avoids too much
condensation in last stages of turbine which avoids blade erosion.
• The heat of combustion gases from furnace is utilised for removal
of moisture from steam and to superheat the steam.
• Super-heaters ususlly have several tube circuits in parallel with
one or more return bends,connected between headers.
• Heat from the hot gases to the vapour in the surperheater is
transferred at high temperatures.
• Therefore promary section of superheater is arranged in counterflow and secondary section in parallel flow to reduce the temp.stressing of the tube wall.
Send us required technical data, such as steam capacity, presure, required temperature etc. We will design accordingly.
