Desuperheaters - Transvac The pressure tank is in the basement, so I don't' think that is an issue. 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. The main function of desuperheater is to minimize the temperature of superheated steam and other vapors (having temperatures above its boiling point, e.g. In a desuperheater, the heat from the steam is not being used and contributes as waste heat which needs to be recovered through integrated systems. Denne energien kan brukes p en effektiv mte til vannoppvarming eller romoppvarming. A larger loopfield is usually beneficial, but it can result in the loopfield warming up slower, so you don't have enough desuperheat. Nedstrmsutstyret er designet for hndtere lavere temperaturer, derfor er det viktig senke temperaturen p dampen. A steam desuperheater is used for lowering the temperature of superheat by bringing the superheat in direct or indirect contact with a coolant. 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. In these types of desuperheaters, the coolant flowrate or the inlet pressure of the superheated steam can be used for controlling the temperature of the desuperheated steam. Of course, it's possible that the smaller tank could have a better first hour rating and recovery rate, but I'd check the specs to be sure. In such cases, it is recommended to use co-current flow to avoid high-temperature risks. That's where knowledgeable professionals should be hired to help guide the project. How does a desuperheater work in a boiler?
