POLYFUNCTIONAL STEP VORTEX HEATER Russian patent published in 2013 - IPC F24J3/00 

FIELD: power engineering.

SUBSTANCE: polyfunctional step vortex heater comprises a reduction thread, connected with inlet and outlet gas lines, in which there is a gas filter, a safety stop valve, a pressure controller, a double-flow and a single-flow ribbed vortex pipes, serially connected to each other by a cold gas flow, forming separate steps closed with a board jacket, besides, the inlet nozzle of the first stage of the vortex pipe is connected with the reduction thread via a tee and a stop device, its high-temperature nozzle is connected via a cyclone to an ejector nozzle, and a low-temperature nozzle is connected with an inlet nozzle of a vortex pipe of the second stage, the high-temperature nozzle of which is connected with a receiving chamber of the ejector, the outlet nozzle of which is connected via a stop device and a tee with a gas filter of the reduction thread, and the condensate outlet from the tray of the cyclone is connected to an external collector of condensate.

EFFECT: higher reliability and efficiency of a polyfunctional step vortex heater.
