GAS-AND-AIR TORCH WITH SUPERSONIC JET Russian patent published in 1996 - IPC

FIELD: autogenous engineering. SUBSTANCE: gas-and-air torch has atomizer head 1 with manifold 2 connected with combustible gas atomizer made in form of circular slot 3, gas supply main 4 and throttling hole 5, mixing chamber 6, whirling ring 7 with skew slots 8 for passage of air from cooling line 9 formed by housing 10 and combustion chamber envelope 11, nozzle cover 12 with manifold 13 connected with air supply main 14 through throttling hole 15, nozzle 16 and housing 10. Line 9 is connected with clearance 18 by means of holes 17. Tapering hole provided in center of head 1 is used for protection of spark-plug electrode 20. Head ensured volume burning of combustible mixture without flame-out. EFFECT: increased flow rate of gas and air to combustion chamber, increased pressure in combustion chamber and availability of supersonic jet. 8 cl, 8 dwg
