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.
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
In power station boilers, the effect of superheaters is to heat the
steam to certain temperature for higher efficiency of the power
station. Reheaters are steam superheaters to reheat the over-worked
long-pressure or middle-pressure steam to certain temperature.
The use of rehearters can further improve heat power of the power
station circulating and control the steam temperature of the end
blades of the steam turbine within allowed range. Zigzag
superheaters and reheaters of the Company are also unique with
rigorous production technique, first-class production flow line and
complete test methods.
