I will watch my utility bill to see if the gas portion of the bill changes. Desuperheater or Steam Desuperheater works on the principle of evaporative cooling whereby the liquid water that is sprayed on the superheated steams results in its cooling. Since the heat capacity of steam and the heat of vaporization is noted to be 0.5BTU/lbf and 1000 BTU/lbf respectively, the amount of water that is required for desuperheating would be less than the amount that one would guess. They are generally used in controlling temperatures of fluid that are sent to the evaporator or used in heat exchangers especially at the entrance to reduce the dimensions and cost.
