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. It requires more energy to maintain a temperature than it does to reduce the temperature for a period and then turn it back up. While specifying the desuperheaters, it is advisable to consult with the manufacturers as per process requirements. Desuperheaters are generally coils situated in the water spaces that are supplied with steam from the superheated section outlet; this type of desuperheater is generally called as internal desuperheaters.

Maybe Doc can provide some data, but it's my understanding that Envision units are not supposed to run the DSH unless conditions are favorable to making the water hotter (not colder.) The issue is in COOLING mode, not heating mode. What keeps a superheater from being damaged by heat before a boiler makes steam? Between the two sections of superheaters is a desuperheater in which water from the feedwater system is injected through spray nozzles into the steam for steam temperature control. It can be calculated using an enthalpy balance whereby the summation of the enthalpy of steam and water is equal to the heat that is present in the exit stream. Part 1: Can the power company turn off power in winter. Blow Out the Line. Thereby reducing the load on the water heater. What is Distributed Control Systems (DCS) ?
