CONICAL CENTRAL PART FOR NOZZLE WITH DOUBLE-FLOW TANGENTIAL INLET Russian patent published in 2003 - IPC

FIELD: power engineering. SUBSTANCE: proposed central part contains longitudinal axis and outer surface in radial direction including truncated figure section limiting outer surface of truncated figure coaxial relative to longitudinal axis and divergent in direction to its base, and curved section being integral with truncated figure section and limiting part of surface obtained at rotation around longitudinal axis of circumference tangential to truncated figure section and having the central located in radial direction outwards. Central part is provided with base with at least one hole to deliver, air, and inner channel. Section of truncated figure contracts in direction to outlet hole of inner channel and terminates in plane of location of outlet hole. Fuel feed tube coaxial to axis passes through base and terminates in inner channel. EFFECT: increased service life. 3 dwg
