Seeking advice on desuperheater design
Thread Content
Hello everyone, I have a question regarding the water bath thermostat; the volume of this thermostat is 1.3 cubic meters. Superheated steam at the lower inlet DN200, with a pressure of 9 barg and a temperature of 250 degrees Celsius. Reduce the pressure to 5 barg, saturated steam. The steam outlet has a diameter of DN200; the normal steam flow rate in the factory is 5 t/h, with a maximum of 8 t/h and a minimum of 1 t/h. What’s confusing now is whether the flow rate after the superheated steam is converted to saturated steam will meet the requirements. Is it necessary to use atomization for the superheated steam, and should the volume be increased? It seems that the experience gained with regenerators cannot be applied to desuperheaters, even though the principles are similar.
Just add a misting nozzle; the volume will definitely need to increase accordingly, the pressure will decrease, and with the water being sprayed, it’s necessary to calculate an appropriate flow rate and pipe diameter!
