Boiler Superheater tube coils for coal power plant
Description
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.
Details
• 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.
Superheater Tube Coils Specification:
Super heaters are the one of the most important boiler sapre parts
that improves the thermal efficiency. High temperature steam boiler
radiant super heater is usually applied in high pressure power
plant boiler.
In the boiler, the role of super heater is to heat the saturated
steam to a certain temperature of superheated steam to increase
power plant efficiency. Repeater essentially further improves the
thermal power plant cycle efficiency.
Steam Super heater Coils: Super heater coils are used in a boiler
to generate saturated steam. The super heater coils are specially
used in Boilers of Power plant. We manufacture Super heater coils
in various grades of Alloy steel and in stain less steel tubes with
or without support & Header as per customer's drawing.
Technical parameters: | |||
Material | carbon steel, alloy steel , or durable heat steel | ||
Tube OD | 30-60mm, or as per requirement | ||
Tube W.T. | 0.8mm- 15mm | ||
Structure | vertical or horizontal | ||
Type | radiant, convection superheater | ||
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.
