DIFFUSION-FLAME GAS BURNER Russian patent published in 2005 - IPC

FIELD: combustion apparatus.

SUBSTANCE: diffusion-flame gas burner comprises housing which is secured to the nozzle from one side and to the control mechanism from the other side. The housing has a branch pipe for supplying gas. The throttle is embedded inside the housing from the side of the nozzle and is connected with the control mechanism through a tie. The control mechanism is provided with a handle for moving the throttle. The tie is movably connected with control mechanism and is locked against radial movements. The nozzle is made of a diffuser whose divergence angle is up to . The throttle is made of a trancated cone whose larger base points in the direction of gas flow. The divergence angle of the cone of the throttle is up to . The difference between the divergence angles of the nozzle and throttle does not exceed . The ratio of the diameter of the nozzle to the greater diameter of the throttle does not exceed 1.4. The blades are secured to the throttle at an angle of no more than to the axis of the burner. The blades are mounted so that the projections of the blade walls overlap free section of the burner independently of their inclination.

EFFECT: enhanced efficiency.
