Efficient ignition conical surface injector

The invention relates to an efficient ignition conical surface injector which can be used as a combustion type steam generating device with liquid oxygen alcohol water as a working medium and can also be used as a combustion type steam generating device with other working media. The injector is mainly composed of an injection disc, an oxygen combustion partition plate, an oxygen combustion nozzle, an oxidizing agent cover plate, an oxidizing agent inlet pipe nozzle, a fuel inlet pipe nozzle and the like, the injection face of the injection disc, the oxidizing agent cover plate and the oxygen combustion partition plate are all conical faces, the normal lines of the conical faces are parallel to the axis of the oxygen combustion nozzle, an ignition channel is arranged on the central axis of the injection disc, ignition fuel gas generated by the igniter enters the combustion area on the downstream of the injection disc through the ignition channel, collides, makes contact with and strengthens mixing at a certain
