Low Temperature Reheater Boiler Superheater And Reheater Tubular Heat Exchangers

Product Function

Reheater is essentially a steam superheater that reheats the low-pressure steam that has done work and reaches a certain temperature. The effect of reheater further improves the thermal efficiency of the power plant cycle, and makes the steam temperature of the turbine blade at the last stage controlled within the allowable range.A reheater is a boiler that heats the steam from the steam turbine into superheated steam.

The reheater has two functions: one is to reduce the humidity of water vapor, which is conducive to the protection of steam turbine blades; Second, the relative internal efficiency and absolute internal efficiency of the turbine can be improved.

For boilers in large power stations, superheaters and reheaters are necessary parts, to a large extend, they have influnced the safety and economy of boilers. Superheaters are the heating surfaces which heat the main steam from the surnatured temperature to the rated superheated temperature, and the reheaters are the heating surfaces which heat the exaust from the steam turbine high pressure cylinder to a certain temperature.When running conditions like boiler loads, coal types change, it is to adjust them to make sure the outlet temperature at the rated level of -10-+5 degrees.
