VerticalScope Inc. All Rights Reserved. I look forward to manufacturers taking it out of their installation manuals. Turn on each faucet and run them until no more water comes out. The desuperheater steam temperature would be set above 3 degrees of the saturation temperature. Tsteam, 2. Since the heat capacity of steam and the heat of vaporization is noted to be 0.5BTU/lbf and 1000 BTU/lbf respectively, the amount of water that is required for desuperheating would be less than the amount that one would guess. The reverse occurs in heating mode. Temperaturen p den overopphetede dampen senkes ved hjelp av en varmeveksler som bruker en kjlevske for senke temperaturen p den overopphetede dampen og kalles en desuperheater.
