"For simple, small systems, dry, saturated steam is generally acceptable. There are three methods for desuperheating: --Direct-contact saturation with water. --Indirect cooling. --Controlled cooling by direct contact with water. The first alternative is used when dry, saturated steam is required. This is the classic situation of producing such steam by use of a saturator. A simple setup is shown in Fig. 2. Indirect cooling is used with an attemperator--this is a device that passes superheated vapor or fluid through it to reduce and control the temperature. Fig. 3 illustrates indirect cooling along with moderate-pressure desuperheated-steam production. The third method is the one most commonly used: Direct contact with water carried out in the steam piping."
Hi All ,
I wanted to calculate the size of the vessel which is used for desuperheating High / low pressure steam using DM water.
radomir,you are the one who understood my question .
Your inputs are good starting point.
