HEAT AND MASS EXCHANGER Russian patent published in 2000 - IPC

FIELD: heat power engineering; applicable in water heating with steam or superheated water with their direct contact. SUBSTANCE: heat and mass exchanger has body round in cross-section and end covers, water supply tangential branch pipes supplying. Supplying steam branch pipes may have nozzles and connected tangentially to body. Installed before steam nozzles are ejecting particles concentric to body and provided with upper and lower walls forming shell. Body may be made of several cylinders different in diameters. Steam branch pipes may be connected with cylinders of different diameters. Branch pipes supplying water may also be located in shells. EFFECT: higher efficiency of operation due to utilization of steam energy for increase of water pressure beyond the apparatus. 6 cl, 4 dwg
