APPARATUS FOR GAS-JET CUTTING OF MATERIALS Russian patent published in 2007 - IPC B23K7/08 F23D14/42 F23D11/34 

FIELD: apparatuses for manual and automatic division cutting of materials, possibly in building, machine engineering, metallurgy emergency and rescue works.

SUBSTANCE: apparatus includes combustion chamber 1 with nozzle 2 and ducts for supplying components of oxidizing agent and fuel to mixing head 3. Combustion chamber 1 has cross section in the form of elongated oval. Mixing head 3 has two mixing members 4 mounted in mixing head along long axis of oval symmetrically relative to axis of combustion chamber and each made in the form Gartman generator. Said generator includes housing 5 with nozzle 6 for feeding one component, rod 11 with duct 12 serving as sprayer for feeding other component and resonator 13 mounted coaxially on end of rod 11 in front of nozzle 6 of generator. Combustion chamber 1 is enclosed with cooling jacket 19 having ribs forming ducts for supplying cooling agent. Apparatus provides complete combustion of fuel directly in combustion chamber.

EFFECT: complete combustion of fuel in combustion chamber causing grown power of gas jet and increased number of types of broken materials.
