DEVICE FOR INCREASING THE STABILITY OF FLOW AND EFFICIENCY OF OPERATION OF THE STEAM-GENERATING CHANNEL Russian patent published in 2018 - IPC F22B1/06 F22D1/12 F28D7/10 

FIELD: machine building.

SUBSTANCE: invention relates to the power machine building and cryogenic systems, and can be used in steam generating systems and devices. Specified tasks in the device for increasing the stability of the flow of the coolant and the efficiency of the steam generator channel containing the throttling washers installed at the inlet and outlet, with three characteristic sections – economizing, transitional and heating gas sections, are solved by the fact that the economizing section has a cross-sectional area increasing in length from inlet to outlet inversely proportional to the change in the average density of the liquid phase of the working product, and also in that the transitional section is made with a variable cross-sectional area increasing in length from inlet to outlet at least twice the cross-sectional area at the outlet of the economizing section, and also in that the heating gas section has a cross-sectional area increasing in length from inlet to outlet inversely proportional to the change in the average density of the gas phase of the working product, and in that the steam generating channel or a part thereof is made in the form of a bellows, and in the case of longitudinal external flow of hot heat carrier around the channel, the bellows has the form of longitudinal corrugations, and in the case of transverse flow – in the form of transverse corrugations.

EFFECT: tasks of the invention are to increase in the heat carrier operation efficiency and flow stability in the steam generating channels.
