START-UP METHOD OF WATER-STEAM JET DEVICE, AND DEVICE FOR ITS PERFORMANCE Russian patent published in 2013 - IPC F04F5/24 

FIELD: machine building.

SUBSTANCE: start-up method of a jet device offers in addition to steam injection through a steam nozzle, discharge of some part of water supplied to the device through a bypass pipe beyond the jet device to a receiving pipeline, which reduces water consumption through the jet device, and by leading to offset of steam condensation shock from a steam nozzle towards a mixing chamber, it creates conditions for start-up of the jet device at lower steam flow rate. The above method is implemented by means of a start-up device of a water-steam jet device including a non-return valve installed on a bypass pipe having flow cross-section diameter that is larger than minimum diameter of flow cross-section of the mixing chamber of the jet device, and a non-return valve installed on water supply pipeline.

EFFECT: reduction of steam flow rate.
