Double-oil-way and double-gas-way combined type fuel nozzle

The invention provides a double-oil-way and double-gas-way combined type fuel nozzle. The double-oil-way and double-gas-way combined type fuel nozzle comprises a main oil way, an auxiliary oil way, a center gas way, an outer gas way and a cyclone. The center gas way is divided into a front section and a rear section which are a main oil way mixing chamber and an auxiliary oil way mixing chamber correspondingly, and the main oil way mixing chamber and the auxiliary oil way mixing chamber are both in a horn shape. The main oil way and the auxiliary oil way spray oil to the front section and the rear section correspondingly, and fuel enters the center gas way and is immediately blown away by high-speed airflow to be atomized for the first time in a liquid film breaking manner. The outer gas way is attached to the periphery of the center gas way in an annular channel manner, and airflow is guided in the main oil way mixing chamber through a series of round holes to atomize the fuel for the second time. The cyclon
