COMBUSTION NOZZLE AND EJECTION METHOD THEREOF, GENERATOR HEAD CONSTRUCTION, PURE OXYGEN COMPOSITE HEAT CARRIER GENERATOR, AND METHOD FOR GENERATING COMPOSITE HEAT CARRIER

摘要

A combustion nozzle, comprising: a nozzle body (1), one end thereof having a fuel inlet (11) and a pure oxygen inlet (12), and the other end thereof forming multiple diaphragm outer cavities (13). The interior of the nozzle body (1) is provided with a fuel passage (14) and a pure oxygen passage (15); one end of the fuel passage (14) is in communication with the fuel inlet (11), and the other end thereof is in communication with the multiple diaphragm outer cavities (13) by means of multiple inclined fuel holes (141); the inclined fuel holes (141) are radially and outwardly inclined along the ejection direction of fuel; one end of the pure oxygen passage (15) is in communication with the pure oxygen inlet (12), and the other end thereof is in communication with the multiple diaphragm outer cavities (13) by means of multiple inclined pure oxygen holes (151); the inclined pure oxygen holes (151) are radially and inwardly inclined along the ejection direction of pure oxygen. The combustion nozzle can uniformly atomize pure oxygen and natural gas, so that the uniformly atomized pure oxygen and natural gas are fully burned in a generator. Also disclosed are an ejection method of a combustion nozzle, a generator head construction, a pure oxygen composite heat carrier generator, and a method for generating a composite heat carrier.
