Abstract

The invention provides a generator for a pure oxygen compound heat carrier and a production method for a compound heat carrier. The generator comprises a generator body and a generator head structure, wherein the generator body comprises a combustion chamber and a steam chamber arranged outside the combustion chamber in a sleeving manner; the generator head structure is provided with a head body, a combustion nozzle and an ignition electrode; the combustion nozzle is provided with a nozzle body, and a plurality of diaphragm outer cavities are formed on one end part of the nozzle body; a fuel channel and a pure oxygen channel are arranged in the nozzle body, the fuel channel communicates with the plurality of diaphragm outer cavities through a plurality of fuel inclined holes, and the fuel inclined holes are radially arranged outwards and slantwise along an injection direction of a fuel; and the pure oxygen channel communicates with the plurality of diaphragm outer cavities through a plurality of pure oxygen inclined holes, and the pure oxygen inclined holes are radially arranged inwards and slantwise along an injection direction of pure oxygen. The generator and the production method, which are provided by the invention, are capable of uniformly atomizing the pure oxygen and natural gas, realizing high-temperature sufficient combustion for the pure oxygen and the natural gas, and finally forming a high-temperature compound heat carrier containing carbon dioxide and steam.

Description

technical field [0001] The invention relates to a generator and a method, in particular to a pure oxygen composite heat carrier generator and a composite heat carrier generation method 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] The multi-component thermal fluid technology is used in oil sand mining, and its core equipment is the generator. At present, the multi-component 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 The way of blending natural gas to achieve high pressure and complete combustion needs. This requires...
