Where is the desuperheater typically located?

The desuperheater is typically located in either the steam drum or water drum. This placement is crucial because the primary function of the desuperheater is to reduce the temperature of superheated steam to a desired level before it enters the turbine or other equipment. By being placed in these locations, the desuperheater can effectively manage the steam's temperature after it has been generated in the boiler and before it is utilized in the steam system.

In the steam drum, the desuperheater helps maintain optimal operating conditions by ensuring that the steam entering the turbine is at the correct temperature and pressure range. This enhances efficiency and protects turbine components from thermal stress that might occur from excessively hot steam.

Having a desuperheater in the main supply line could lead to complications in controlling steam temperature effectively. Adjacent to the steam traps or inside the combustion chamber would also not be suitable locations, as this would not facilitate the necessary temperature reduction after steam generation where precise control is needed. Therefore, the design and function of the steam system determine that the optimal location for the desuperheater is indeed in the steam drum or water drum.
