COAXIAL JET NOZZLE Russian patent published in 2001 - IPC

FIELD: mechanical engineering; mixing and atomizing fuel components. SUBSTANCE: proposed nozzle has hollow tip connecting space with one fuel component with burning zone, bushing enclosing the tip with ring clearance and connecting space with other fuel component with burning zone. Radial slots are made in outlet part of tip. Outlet section of bushing inner surface is made equidistantly to outer surface of tip slots, section area at outlet between equidistant surface of bushing and tip slots being F_sa = (0,6-2,2)F₀ where F₀ is area of slot section at tip outlet. EFFECT: improved combustion of fuel components by increasing surface of contact. 3 cl, 3 dwg
