Embodiment 1

[0022] Such as figure 1 The shown air oxygen-enriched pure oxygen three-purpose burner includes a central oxygen channel 1, a gas channel 2 wrapped outside the central oxygen channel 1, 6 air channels 4 evenly distributed outside the gas channel 2, and fixedly installed in the air Outer epoxy gas channels 3 in the channel 4, the number of 3 outer epoxy gas channels is equal to the number of 4 air channels, and the diameters of the combustion side of the central oxygen channel 1 and gas channel 2 gradually shrink from the inside to the outside. The left end of the central oxygen channel 1 is fixedly installed with a central oxygen channel connector with a regulating valve, through which pure oxygen is connected. The left end of the gas channel 2 is fixedly equipped with a gas channel connector with a regulating valve, and accesses the gas through the gas pipeline connector. The left tail of the air channel 4 is fixedly equipped with an air channel connector with a regulating v...

Embodiment 2

[0024] The difference between embodiment 2 and embodiment 1 is that the number of 3 outer epoxy gas passages is less than the number of 4 air passages, which helps to adjust the air and oxygen intake.

Embodiment 3

[0026] The difference between embodiment 3 and embodiment 1 is that a number of gas nozzles 8 communicating with the gas passage 2 are evenly opened in the circumferential direction of the combustion side of the gas passage 2, and the diameter of the gas nozzle 8 is smaller than that between the outer wall of the central oxygen passage 1 and the inner wall of the gas passage 2. distance, the number of gas spouts 8 is 6. The gas is sprayed out to the combustion channel 10 through the gas nozzle 8 to support combustion.

[0027] When the air-oxygen-enriched pure oxygen three-purpose burner is used, firstly select different combustion-supporting methods according to different process requirements. The supply of central oxygen is adjusted through the regulating valve on the central oxygen pipeline, and the supply of gas is passed through the gas channel 2. The regulating valve is adjusted, the air supply is adjusted through the regulating valve on the air channel 4, and the supply...

Abstract

The invention belongs to the technical field of combustors and relates to an air, oxygen-enriched and pure-oxygen triple-purpose combustor. The air, oxygen-enriched and pure-oxygen triple-purpose combustor comprises a coal gas channel wrapped outside a central oxygen channel, a plurality of air channels distributed uniformly outside the coal gas channel and outer ring oxygen channels fixedly mounted in the air channels, and the number of the outer ring oxygen channels is less than or equal to that of the air channels. The combustion side of the central oxygen channel is provided with central oxygen nozzles. The combustion side of the coal gas channel is provided with coal gas nozzles. The outlet ends of the air channels serve as air nozzles. The outlet end of the outer ring oxygen channelsserve as outer ring oxygen nozzles. Burner bricks matched with the air channels are fixedly mounted on the peripheries of the combustion sides of the air channels. The channel between the central oxygen channel, the combustion side of the coal gas channel and the burner bricks serves as a combustion channel of the combustor. Through the combustor, the three air combustion supporting, oxygen-richcombustion supporting and pure oxygen combustion supporting combustion modes can be implemented, and a user can flexibly select and adopt the combustion modes according to the heating process and oxygen and fuel conditions, and the energy conservation and emission reduction effects can be achieved to the maximum extent.

Description

technical field [0001] The invention belongs to the technical field of burners, and relates to an air-oxygen-enriched pure oxygen three-purpose burner. Background technique [0002] Oxygen-enriched combustion technology is widely favored due to its advantages such as high combustion temperature, less enthalpy carried away by flue gas, good ignition characteristics and flame stability. Especially for the combustion of some inferior fuels and low calorific value fuels, significant economic benefits can be produced. However, as the oxygen concentration increases, the oxygen-enriched combustion temperature increases, and the thermal NO X If it rises, it may burn the combustion equipment. Moreover, the combustion flame of the oxy-enriched combustion is short and the energy is concentrated, so the oxy-enriched combustion has certain limitations in practical applications. [0003] Traditional oxygen-enriched burners usually keep the burner away from the high temperature area to ...
