The invention relates to a pure oxygen combustion technology. A pure oxygen combustion device and an application process thereof are included. The pure oxygen combustion device comprises a base which is arranged on a crucible and provided with a fuel gas mixing nozzle; a heat exchange body extending in the axial direction of the fuel gas mixing nozzle is arranged in the middle of the interior of the fuel gas mixing nozzle; the fuel gas mixing nozzle is further provided with a plurality of fuel gas channels which are located on the outer side of the heat exchange body and annularly arranged with the heat exchange body as the center; the fuel gas mixing nozzle is further provided with a plurality of smoke channels which are annularly arranged with the heat exchange body as the center and are located on the outer sides of the fuel gas channels; a gas mixing fan is arranged in the fuel gas mixing nozzle; an upper oxygen mixing nozzle and a lower oxygen mixing nozzle are vertically formed in the position, located on the lower side of the fuel gas mixing nozzle, of the base in sequence; and the ends, facing the interior of the crucible, of the upper oxygen mixing nozzle and the lower oxygen mixing nozzle are inclined upwards. Through the pure oxygen combustion device and the application process thereof, fuel gas combustion is sufficient, the combustion heat utilization rate is high, the heat loss is small, and the waste gas yield is small; and heat can be effectively dissipated through the nozzles, and the service life is long.
Description
technical field [0001] The invention relates to industrial gas combustion technology, in particular to a pure oxygen combustion technology. Background technique [0002] A large number of burners are used in the production of the industrial field. It is one of the main equipment for energy consumption, carbon emission and environmental pollution. Its efficiency directly affects the effect of energy utilization and environmental protection. Therefore, people have attached great importance to the improvement of burner technology for a long time. Most of the burners currently used are air-assisted combustion. During the combustion process, a large amount of N2 is heated into high-temperature flue gas and discharged, which not only wastes energy, but also pollutes the environment. Composition of air: O2 is about 21%, N2 is about 79%. If a burner with air as the supporting gas is used, 79% of N2 absorbs heat and is completely discharged during the combustion process, and only 21...
