The desuperheater helps in lowering the high temperature of the steam to low temperatures that will help in safely carryout the other process operation. A desuperheater's function is to produce steam temperatures approaching saturation temperature (typically to within 3C). An attemperator is used for regulating the steam temperature of the boiler. 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. Ved oppvarming av vann i boliger eller husholdninger ved bruk av desuperheaters, brukes varmen om sommeren til oppvarming av vannet. Faktorer som pvirker installasjonen av desuperheateren.
