Super heaters are used in steam power plants to remove the last trace of moisture from the saturated steam leaving the boiler tubes and also to increase its temperature above the saturation temperature from the heat of combustion gases from the furnace.

Re heaters are used in steam power plants to re superheat the partly expanded steam from the turbine so that the steam remains dry as far as possible through the last stage of the turbine.
