A blowdown vessel 108 is shown in FIG 1 This includes a storage chamber 105 for containing a blowdown mass 106 from a up to a water level 110 and a transfer coil 107 The blowdown vessel 108 also includes an overflow conduit 111 extending from near the bottom of the vessel and terminating in a drain 109Get a Quote
As the flash steam is generated the condensate that remains is used to preheat the feed water using a low-pressure liquid For smaller lower pressure requirements the HX Series system utilizes a higher pressure liquid to liquid without a flash tank to do the heat recovery jobGet a Quote
During boiler blow down Boiler water is removed at high temperature condition ie equivalent to steam temperature The concentrated water leaving boiler is the area of direct energy loss Water coming out from the boiler is good source of heat which can be recovered and utilized at boiler deaerator or feed water preheating Methodology : Boiler water coming out from boiler blowdown may be fed to flash separator where flashGet a Quote
