Combustor based on multi-zone combustion

Abstract

The invention provides a combustor based on multi-zone combustion. The combustor comprises a combustor barrel body, a fuel gas injection system and a flame stabilizing disc, wherein, the fuel gas injection system and the flame stabilizing disc are arranged in the combustor barrel body; the fuel gas injection system comprises a central fuel gas pipe and a plurality of annular fuel gas spray pipes which are rotationally and symmetrically arranged by taking the central fuel gas pipe as the center; a plurality of central fuel gas through holes are formed in the tail end of a central fuel gas spraypipe; the fuel gas injection system further comprises a plurality of fuel gas branch pipes which are rotationally and symmetrically arranged by taking the central fuel gas pipe as the center, and oneends of the fuel gas branch pipes are in communication with the annular fuel gas spray pipes; first flow distribution through holes are formed in the fuel gas branch pipes in the radial direction ofthe combustor barrel body, and second flow distribution through holes are formed in the tail ends, away from the annular fuel gas spray pipes, of the fuel gas branch pipes; and annular fuel gas through holes are formed in the tail ends of the annular fuel gas spray pipes. By applying the technical scheme, the combustion efficiency can be improved, and the combustor can be heated uniformly.

Description

technical field [0001] The invention relates to the field of burners, in particular to a burner based on multi-zone combustion. Background technique [0002] Ordinary burners have completely failed to meet the temperature requirements of today's industrial level. And the burner also has the defect of incomplete combustion at the same time, which will cause great harm to the environment, and at the same time cause harm to the user's body, and the residual gas will also increase the risk; Low efficiency is the main factor for generating NOx, and the emitted NOx will cause pollution to the atmospheric environment. [0003] Nowadays, ordinary burners have many defects: short contact time between gas and air, uneven mixing, resulting in insufficient combustion, not only wasting energy, polluting the environment, but also the flame temperature during combustion is low, which is not suitable for high-temperature production applications.

[0002] Ordinary burners can no longer meet the temperature requirements of today's industrial level

And the burner also has the defect of incomplete combustion at the same time, which will cause great harm to the environment, and at the same time cause harm to the user's body, and the residual gas will also increase the risk; Low efficiency is the main factor for generating NOx, and the emitted NOx will cause pollution to the atmospheric environment

[0003] Nowadays, ordinary burners have many defects: short contact time between gas and air, uneven mixing, resulting in insufficient combustion, not only wasting energy, polluting the environment, but also the flame temperature during combustion is low, which is not suitable for high-temperature production sites
