Boiler Superheater Coils The Ultimate Solution for High-Temperature
Steam Generation
Superheater
Fossil fuel power plants often have a superheater section in the
steam generating furnace.The steam passes through drying equipment
inside the steam drum on to the superheater, a set of tubes in the
furnace. Here the steam picks up more energy from hot flue gases
outside the tubing, and its temperature is now superheated above
the saturation temperature.
Reheater
Power plant furnaces may have a reheater section containing tubes
heated by hot flue gases outside the tubes. Exhaust steam from the
high-pressure turbine is passed through these heated tubes to
collect more energy before driving the intermediate and then
low-pressure turbines.

furnace. |
Function
Superheater is to increase the temperature of the steam above its saturation
point.
Reheater is basically a superheater that superheats steam exiting the
high-pressure stage of a turbine. The reheated steam is then sent
to the low-pressure stage of the turbine. By reheating steam
between high-pressure and low-pressure turbine it is possible to
increase the electrical efficiency of the power plant cycle beyond
40%.The reheat cycle is used in large power boilers since it is
feasible economically only in larger power plants.
Our custom superheater coil is designed specifically for use in
boilers and can be used to replace existing superheater coils in
existing boilers, or designed and manufactured to fit into new
boilers. Our superheater coil is designed to provide superior heat
transfer performance and maximum durability in high-pressure and
industrial applications.
