Large extension spray cone-angle slinger ring atomizer structure

The invention belongs to the technical field of aero-engine combustor, and particularly relates to a large extension spray cone-angle slinger ring atomizer structure. An effective mean to improve thethermal efficiency of a small turbine engine is to improve the mixing of the head portion of a flame tube. The invention provides a large extension spray cone-angle sling ring atomizer technology, a swirl structure is added at a nozzle of a slinger ring atomizer, and under the action of centrifugal force of the slinger ring atomizer, fuel can leave the slinger ring atomizer in the form of swirlingflow; and on the basis of good atomization, the injection angle of the fuel is increased, the residence time of the fuel in the flame tube is increased, the oil and gas mixing is enhanced and the combustion efficiency is improved. An optimization design of corresponding parameters of various combustion organizations is carried out for the purpose of simple machining and high combustion efficiency, and a simple and efficie
