Novel double-gas-path combustion chamber air atomizing nozzle

The invention provides a novel air atomizing nozzle for a double-gas-path combustion chamber. The invention provides the novel air atomizing nozzle for the double-gas-path combustion chamber. The nozzle adopts a scheme of combining double gas paths and a main oil path to enhance atomization and evaporation of fuel oil. Fuel oil from the main oil way is atomized into small liquid drops for the first time after passing through the special-shaped hole, the small liquid drops are sheared and collided with air from the main air passage, secondary atomization is achieved, and remaining fuel oil enters the main oil way contraction section after passing through the rotational flow blade at the tail end of the main oil way straight-through section and is sprayed out in an accelerated mode. Air from the auxiliary air channel enters the contraction section of the auxiliary air channel after passing through the rotational flow blades at the tail end of the straight-through section and is sprayed out in an accelerated mod
