INJECTOR WITH TWO-FLOW TANGENTIAL ENTRY AND SEPARATED FLAME

摘要

FIELD: power engineering. SUBSTANCE: proposed injector has longitudinal axis and two spiral elements with cylindrical dome, axial lines of elements being displaced relative to each other. Overlapping ends of elements form inlet slot to feed fuel-air mixture into injector. End face plate of combustion chamber is provided with central hole to feed fuel and air into combustion chamber while other opposite end face plate blocks area of injector flow. Spiral elements are secured between said end face plates. Central part is located between said elements coaxially relative to longitudinal axis and it has base with at least one hole to deliver air passing through hole and inner channel, and also truncated figure section and aerodynamically shaped inclined sections preventing formation of reverse flow and providing stabilization of flame between said end face plates. EFFECT: increased service life. 6 cl, 3 dwg
