reheating is done when more than one turbine is used to
expand the steam.firstly,it is expanded in a high pr
turbine where the pressure and temp are reduced.then it is
allowed to expand in low pr turbine.when the steam comes
out of high pr it will be almost in wet state.so if it is
allowed to expand in another turbine means corrosion of
blades takes place.so the steam is reheated in a reheater.
