Abstract

The invention relates to a fuel gas flame-free pure oxygen burner used in a large metallurgical industrial furnace, and belongs to the technical field of efficient burning equipment manufacturing. According to the fuel gas flame-free pure oxygen burner, the purpose of pure oxygen burning is achieved, flame-free burning is also achieved, no nitric oxide is produced, and the service life of the fuel gas flame-free pure oxygen burner can be long at the high-temperature pure oxygen environment. According to the technical scheme, the fuel gas flame-free pure oxygen burner comprises a base and a ventilation mechanism which is composed of a primary oxygen air pipe, a secondary oxygen air pipe, a secondary oxygen pressure stabilizing cavity, a fuel gas air pipe, a fuel gas pressure stabilizing cavity, a cyclone and a smoke nozzle.

Description

technical field [0001] The invention belongs to the technical field of high-efficiency combustion equipment manufacturing, and relates to a gas flameless pure oxygen burner, which is used for large-scale metallurgical industrial furnaces. Background technique [0002] In the current combustion technology, a large amount of carbon dioxide and nitrogen oxides are emitted due to combustion, which will have a great impact on the environment and lead to a global greenhouse effect. With the development of combustion technology, the new pure oxygen combustion technology will significantly reduce the emission of greenhouse gases in the combustion process, because the production of pure oxygen for combustion will increase the production cost virtually, and a large amount of oxygen is released in the iron and steel metallurgy industry It also leads to the waste of energy, so it has important economic and technical value to use the excess oxygen in the iron and steel metallurgy industr...
