AIR-GAS INJECTOR BURNER FOR IGNITION OF GAS-OXYGEN MACHINE CUTTING TORCHES Russian patent published in 2012 - IPC F23Q9/00 F23D14/64 

FIELD: heating.

SUBSTANCE: air-gas injector burner for ignition of gas-oxygen machine cutting torches includes mixer with electrode, gas supply nozzle with a channel, which is installed at mixer inlet; mixer is provided with additional electrode fixed through insulator in gas supply nozzle coaxially to mixer; besides, in gas supply nozzle with respect to the channel there made are holes uniformly located together with channel in angular direction and located at equal distance from nozzle longitudinal axis, and working end of additional electrode and mixer electrode are located at the distance from mixer outlet, which is equal to inner diameter of mixer.

EFFECT: reliable operation with simultaneous simplification of the design owing to stable formation of long ignition flame in the whole range of working pressures of combustible gases in main factory circuits without using any adjusting elements in automatic operating mode of machine for thermal cutting of metals.
