Abstract
The invention discloses a double-oil-way nozzle structure which comprises an oil supply pipe seat and a nozzle seat, a main oil pipe and an auxiliary oil pipe are arranged in the oil supply pipe seat, a main oil way mechanism connected with the main oil pipe is arranged in the nozzle seat, an auxiliary oil way mechanism connected with the auxiliary oil pipe is arranged in the nozzle seat, and the main oil way mechanism and the auxiliary oil way mechanism are arranged in the nozzle seat. The output end of the main oil way mechanism is provided with a radial swirler and an axial swirler, and the output end of the auxiliary oil way mechanism is provided with a Laval nozzle. The beneficial effects are that the swirl plate is provided with the swirl hole used for allowing fuel oil to pass through and generating swirl, the fuel oil generates swirl so as to improve the atomization quality of the fuel oil of the auxiliary oil path, the whole auxiliary fuel oil is differentiated, the swirl effect of the fuel oil is better, ignition of a combustion chamber is more convenient, gas is pressurized by an air pump and enters through an air inlet channel, and the fuel oil atomization effect is improved. And the cyclone mechanism is matched, so that air entering the cyclone mechanism generates cyclone, and the ignition performance generated by subsequent air and fuel oil is better.
