Description

Technical Field

[0001] The utility model relates to the technical field of burners, in particular to an environmentally friendly pulverized coal burner. Background Art

[0002] The burner is the core component of a pulverized coal boiler. Its function is to spray pulverized coal and air into the coal-fired boiler at a certain ratio and speed to produce a violent gasification reaction. The performance of the pulverized coal burner can directly affect the thermal efficiency and environmental emissions of the boiler. There are many ways to burn coal. The coal-burning technologies used in industrial kilns are roughly the following: layer combustion, pulverized coal combustion, gasification technology, water-coal slurry combustion technology, pulverized coal liquid slag cyclone combustion technology, etc. Pulverized coal burner refers to a device that can fully burn pulverized coal in a short time and generate high-temperature vortexes.

[0003] For example, the Chinese patent with publication number CN217329773U proposes a pulverized coal burner, which forms a gas-powder mixture by fully stirring the pulverized coal and the primary air provided by the first air guide tube. The combustion-supporting air added by the secondary air duct continues to provide sufficient oxygen for the pulverized coal, so that the gas-powder mixture can be fully burned at the combustion nozzle, reducing the waste of pulverized coal and a large amount of nitrogen oxides, thereby reducing costs. However, in this solution, since the pulverized coal directly enters the combustion nozzle through the set pulverized coal air duct for combustion, due to various reasons, the gas-powder ratio may not be able to adapt to the current equipment operating conditions. When the gas-powder ratio is not coordinated, for example, when there is an excess of coal in the gas-powder mixture, the powder-gas mixture may be difficult to fully burn. There are certain limitations and it may affect the environment. Utility Model Content
