A FEED WATER EQUIPMENT OF INTERNAL CIRCULATION PUMP SYSTEM WHERE STEAM AND WATER ARE HEATED AND COOLED RECIPROCATINGLY FOR MICRO-CONDENSATION GENERATING

摘要

A feed water equipment of an internal circulation pump system for micro-condensation generating involves that steam and water are heated and cooled reciprocatingly, particularly a boiler feed water equipment of micro-condensation generating that an exhaust steam flow(51) from a steam turbine(2) flows through a circulation unit assembly of tube bundles of primary pipes(10), hot tube bundles of double-semicircle pipes(57) or double sleeves group system(61), heat is instantly exchanged between a feed water flow(52) and the exhaust steam flow(51) which are separated from each other by heat exchange walls of tube bundles, tube bundles of superconductive heat pipes(35) or heat exchange walls of inner sleeves(60), and whose flow direction is opposite, the exhaust steam flow(51) is cooled continuously via a feed water pump(22) and becomes the feed water flow(52) which is put into the other side (end, circle) of the heat exchange walls in manner of a closed cycle.
