<p>CLOSED PRESSURIZED FEED WATER SYSTEM SUPPLYING FLASH STEAM TO A LOWER PRESSURE PROCESS A closed pressurized feed water system supplying flash steam to a lower pressure process and with no steam loss in the closed system. The flash steam delivered to the lower pressure process is sufficient to reduce the pressure in the feed water system so that a steam trap in the closed system will operate and permit the hot condensate to be returned to the boiler. Also, new make up water may be added to the system to compensate for any steam loss. In the high pressure closed system about 96.68% of the condensate is returned to the boiler and only about 3.32% is needed for new make up water.</p> |
