KINETIC PUMP-HEAT EXCHANGER Russian patent published in 2003 - IPC

FIELD: heat power engineering, applicable as a steam kinetic pump for delivery of liquid without any use of a mechanical pump at a rise of liquid pressure due to the use of the kinetic energy of the heat-transfer agent (steam) at a simultaneous use of it as a steam direct-contact heat exchanger. SUBSTANCE: the kinetic pump-heat exchanger has a body with end covers inlet branches of liquid and operating steam, tangential nozzles connected to the body interior through the end covers and (or) body wall and to the steam inlet branch directly or through an intermediate chamber, liquid outlet branch connected to the body tangentially, the liquid inlet branch is connected to the body interior through the central part of the end cover, or two inlet branches are installed and connected to the body interior through both end covers, and the kinetic pump-heat-exchanger may be made both as a single-stage and as a double-and more stage one, where the outlet branch of the previous one is connected to the inlet branch. EFFECT: provided heating of liquid and its conveyance to the user without use of any pumps. 6 cl, 12 dwg
