Abstract

The invention provides a head structure for a generator and an assembly method for the head structure. The head structure for the generator comprises a head body, a combustion nozzle and an ignition electrode, wherein a nozzle channel and an ignition electrode channel are formed in the head body; the combustion nozzle is arranged in the nozzle channel and is provided with a nozzle body; a fuel inlet and a pure oxygen inlet are formed in one end of the nozzle body; a plurality of diaphragm outer cavities are formed in the other end of the nozzle body; a fuel channel which communicates with the fuel inlet is formed in the nozzle body; the other end of the fuel channel communicates with the plurality of diaphragm outer cavities through a plurality of fuel inclined holes; the fuel inclined holes are radially formed in an outward inclined manner in the spraying direction of fuel; a pure oxygen channel which communicates with the pure oxygen inlet is also formed in the nozzle body; the other end of the pure oxygen channel communicates with the plurality of diaphragm outer cavities through a plurality of pure oxygen inclined holes; the pure oxygen inclined holes are radially formed in an inward inclined manner in the spraying direction of pure oxygen; and the ignition electrode is arranged in the ignition electrode channel. The head structure for the generator resists high temperature and oxidation, has a safe and reliable structure and is long in service life.

Description

technical field [0001] The present invention relates to a generator head structure and an assembly method thereof, in particular to a generator head structure and an assembly method thereof in the high-pressure combustion technical field. Background technique [0002] Multivariate thermal fluid technology Thermal exploitation of heavy oil is a very efficient new technology, which has the advantages of high combustion efficiency, zero carbon injection, environmental protection and energy saving. Well productivity and enhanced oil recovery. [0003] Multivariate thermal fluid technology is used in oil sand mining, and its core equipment is the generator. At present, the composition of the multivariate thermal fluid output by the generator requires the removal of nitrogen or the reduction of nitrogen content, mainly through the use of pure oxygen with an oxygen content of more than 90% and natural gas Blending way to achieve high pressure and complete combustion needs. [000...
