EJECTOR-DIFFUSER DEFLECTOR Russian patent published in 2022 - IPC F23L17/02 F23J11/00 F24F13/26 F24F7/02 

FIELD: thermal power engineering.

SUBSTANCE: invention relates to the field of thermal power engineering and can be used to improve the efficiency of industrial and domestic heating units or to the field of artificial ventilation. The ejector-diffuser deflector contains a cylindrical pipe with a conical diffuser mounted on it, a shell and a conical screen. From the outside, at the mouth of the conical diffuser, a skirt tapering upwards is installed, on which the shell is installed with a gap so that their inner surfaces form an annular channel tapering at the outlet. The shell is made profiled with a narrowing in the central part and an expansion in the upper part. The conical screen is attached above the outlet section of the shell.

EFFECT: exclusion of the effect of a periodic drop in rarefaction in the furnace of heating units due to the “compressed” hot jet by the wind flow and an increase in the efficiency of ventilation systems.
