Embodiment Construction

[0008] Flue gas circulation high-temperature air energy-saving and environmentally friendly combustion technology is to mix the flue gas after fuel combustion with combustion-supporting air and then heat them together to form high-temperature gas, which is then burned with fuel.

[0009] Below with reference to accompanying drawing, content of the present invention is further elaborated:

[0010] As shown in the figure, a duplex airflow channel is closely arranged on the left and right sides of the original burner position of the boiler furnace wall 13, which are channel 1 and channel 2 respectively. The two channels adopt full-duplex working mode. When the work starts, the control The valve 3 is opened, and the channel 1 starts to suck the high-temperature flue gas on the left side of the burner 12 under the action of the induced draft fan 7. , after a certain period of time, the control valve 6 is opened, and under the guidance of the induced draft fan 7, the channel 2 start...

Abstract

The invention relates to a technology of combustion, in particular to a flue gas recirculation high-temperature air energy-saving and environmental protection combustion technology which is applied to the boiler combustors such as utility boilers, industrial boilers, metallurgical heating furnaces and the like. The invention adopts the concept of flue gas recirculation combustion, realizes real oxygen-poor high-temperature combustion, stabilizes theoretical flame temperature, creates the reducing flue gas environment, reduces oxidation combustion loss, reduces generation of NOX in two-way, and greatly saves fuel. The invention not only saves energy and reduces emission, but also achieves nitre reduction.

Description

technical field [0001] The present invention relates to a combustion technology in boiler combustion equipment, especially the flue gas circulation high-temperature air energy-saving and environment-friendly combustion technology widely used in burners such as industrial boilers, metallurgical heating furnaces, hot blast furnaces, roller hearth furnaces, ceramic kilns, etc. . Background technique [0002] With the increasing environmental protection requirements, desulfurization and denitrification have been widely valued. Desulfurization is mainly implemented in coal-fired power plants, while destocking is not only required in power plant boilers, but also in general industrial furnaces, such as cement rotary kilns, metallurgical heating furnaces, etc. need to be implemented. If pollutants can be controlled at the initial stage of production, it will undoubtedly reduce the pressure and cost of the governance stage. [0003] The traditional boiler or heating furnace burner...
