BURNER Russian patent published in 2002 - IPC

FIELD: applicable in installations for controlled steady-state pulsating combustion. SUBSTANCE: the burner has a cylindrical body connected to the source of blast air, installed in its axis at the outlet are a rigidly fastened contraction-diffuser probe and a thin-walled hollow cylinder for longitudinal displacement, installed also for longitudinal displacement are rigidly fastened a fuel-injection nozzle and a tapered combustion stabilizer with the maximum diameter of radial section not exceeding the pinch diameter of the probe, an axial vane swirler located inside the thin-walled hollow cylinder at the inlet of the blast air stream, the contraction-diffuser probe is installed in the burner body with a radial clearance forming the boundary passage and converging in the direction of motion of blast air, the combustion stabilizer is made in the form of a tapered jet-stabilizer is also installed in the body axis with a radial clearance forming the boundary passage. EFFECT: enhanced economical efficiency of the burner due to production of qualitative fuel-air mixture. 2 cl, 1 dwg
