Her vil kjlevsken som benyttes vre en vske eller en gass som fr strmme gjennom den ene siden av varmeveksleren mens den overopphetede dampen passerer gjennom den andre siden. Grunnen til at overheteren ikke pvirkes av varmen er at dampen som strmmer gjennom overheteren avkjler metalloverflatene og andre deler og reduserer dermed skader p overheteren. 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. An attemporator controls the steam temperature while a desuperheater removes whatever superheat there is in steam and reduces the temperature to a point at or nearly at saturation temperature. Desuperheater-spoler, spesielt den mindre typen har en rr-til-rr-design. Turn on each faucet and run them until no more water comes out. Desuperheatere er hovedsakelig av to typer, dvs. desuperheater system functions as a closed-loop adia-batic process, these two laws can be used to derive the following equation to determine the amount of injec-tion water required to cool the superheated steam to a specic temperature: (3) m W = mass ow rate of water m OS = mass ow rate of the outlet steam h IS = enthalpy of the inlet . 1.

On the other hand, the heat absorbed by the liquid coolant helps it in the evaporation process. When you find it, close the valve off by turning the handle to the right and making sure its closed tightly. 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.
