JET STEAM-WATER HEATING DEVICE Russian patent published in 2017 - IPC F04F5/00 F04F5/24 F04F5/54 

FIELD: heating.

SUBSTANCE: device includes a jet apparatus 1, an electric pump 2, a vacuum pump 3 comprising an inlet chamber 4 with tangential supply 5 of the heat-carrying medium and an inlet nozzle 6 located in its central portion 7, and an outlet chamber 8 with an outlet nozzle 9to discharge the heat-carrying medium to the consumer, a ring gap 10 formed by an expanding cone 11 and a hydraulic throttle 12 in the form of a truncated cone, wherein the construction of the jet apparatus 1 is similar to the vacuum pump 3 construction, its inlet chamber 13 is provided with an outlet nozzle 14 to discharge the heat-carrying medium from its central part 15, and its outlet chamber 16 is provided with discharge nozzle 17 for the heat-carrying medium discharge. Jet apparatus 1 is mounted axially with respect to the vacuum pump 3 and oppositely to its inlet chambers 13 and 4, connected by a pump line 18 with a shut-off valve 19. Inlet pump line 20 and outlet pump line 21 of the vacuum pump 3 heat-carrying medium and a pump line 22 of the heat-carrying medium discharge from the jet apparatus 1 are provided with electric pumps 23, 24, 25, and the said pump lines and a pump line 34 of the heat-carrying medium inlet are provided with temperature sensors 26, 27, 28 and 29 respectively. In addition, hydraulic throttles 33 and 12 of the jet apparatus and the vacuum pump are made in the form of a truncated cone, and the jet apparatus includes a ring gap 31 formed by an expanding cone 32 and a hydraulic trottle 33.

EFFECT: increased heat output of heat-carrying medium.
