FIELD: torch cutting devices. SUBSTANCE: device has head with the following components arranged in it: nozzle, gas generator with combustion chamber and prechamber, fuel supply line (fuel may be supplied tangentially relative to walls of nozzle), oxidizer supply line brought in communication with combustion chamber and prechamber by means of passages and igniter. Diameter of combustion chamber is more than that of prechamber. Fuel supply line is brought in communication with prechamber and prechamber is brought is communication with combustion chamber. Passage feeding oxidizer to combustion chamber is made in form of circular manifold which makes it possible to supply oxidizer to zone adjoining inner wall of combustion chamber. EFFECT: completeness of combustion, reduction of overall dimensions and mass. 5 cl, 2 dwg |
