Description

Technical Field

[0001] The present application relates to the technical field of burners, and more specifically, to a side-inlet cooling liquid fuel burner. Background Art

[0002] The furnace head is an important part of the open furnace. The combustion of fuel, the direction and shape of the flame, the exhaust gas discharge and the distribution in the heating chamber are all related to the structure of the furnace head. In addition, the heating of the charge, the smelting time and the fuel consumption are all directly affected by the structure of the furnace head.

[0003] Existing burners generally use side air inlet or bottom air inlet, but no matter which method is used, since the fuel is a liquid fuel with a certain viscosity, it is very easy to gel after high temperature, thereby clogging the fuel injection nozzle and causing the burner to fail to work normally.

[0004] In order to solve the above problems, the present application provides a side-inlet air cooling type liquid fuel burner. Utility Model Content

[0005] The side-inlet cooling liquid fuel burner provided in the present application adopts the following technical solution:

[0006] The vents are formed on one side of the bottom wall of the furnace shell and the vents are formed on the other side of the bottom wall of the furnace shell. The vents are formed on one side of the bottom wall of the furnace shell and the vents are formed on the other side of the bottom wall of the furnace shell. The vents are formed on one side of the bottom wall of the furnace shell and the vents are formed on the other side of the bottom wall of the furnace shell.

[0007] Furthermore, there are three mounting holes, which can make the installation more stable and easier during use.

[0008] Furthermore, the relief groove is semicircular and surrounds the oil injection nozzle. This design supports easy assembly and maintenance of the furnace shell.

[0009] Furthermore, the diameter of the air outlet is smaller than the diameter of the air inlet pipe. The purpose of this design is to increase the wind pressure inside the burner and speed up the wind flow rate to quickly cool down the fuel injector. The surface of the fuel injector adopts a threaded structure, which can better increase the heating area of ​​the fuel injector. When the wind in the air duct passes through, the supply temperature can be better reduced.

[0010] In summary, this application includes the following beneficial technical effects:

[0011] Extending the side air inlet pipe to the other side of the furnace shell wall can better protect the service life of the fuel injector, keep the oil in the fuel injector in a non-high temperature state during operation, avoid the gelation of the fuel, and also enable the fuel in the furnace to burn more fully.
