SURFACE CONDENSER OF STEAM Russian patent published in 1996 - IPC

FIELD: power production. SUBSTANCE: device has housing 1, which is filled with boiler water, C-shaped steam tubes 2, which are located in radial direction and have differ horizontal parts, and feeding tube 3 and exhausting tube 4. Housing 1 has compensating condenser tubes 5, in which input and output parts of tubes 2 are fixed and are connected to distributing collector 6 and gathering collector 7. Steam tubes 2 are connected to steam source which has greater temperature than after second stage of steam heater or are used as first steam run tubes. Steam tubes 2 having lesser length of horizontal ends are connected to steam supply with lesser temperature, for example, after triple steam cooling or they are used as second steam run tubes. Condenser has drain 8. EFFECT: decreased temperature difference in points where tubes are connected. 3 dwg
