Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of full premix burners, in particular to a combustion head for a multi-stage full premix burner. Background Art
[0002] In the broad concept of burners, household water heaters, gas stoves, and even lighters can be considered as a type of burner. According to its working principle, a burner can be defined as a device that converts substances into heat energy through a chemical reaction called combustion, that is, air and fuel are mixed in appropriate proportions through a premixing device to make them fully burn. Burners have a variety of classification methods based on their different properties. According to the fuel method, they are divided into oil burners, gas burners, light oil burners, and dual-fuel burners. Among them: in specific applications, oil burners will be divided into light oil burners, heavy oil burners, etc.; gas burners are divided into natural gas burners, city gas burners, etc.
[0003] The burner includes a multi-stage fully premixed burner, in which multiple gas pipelines are arranged for transmitting the gas. These channels are usually integrated to ensure that the gas and air can be evenly mixed and burned in each combustion stage. However, when the multi-stage burner head needs to be maintained, replaced or adjusted at a later stage, it cannot be quickly disassembled, thereby reducing its practicality. At the same time, the gas density is one of the important parameters affecting the combustion process. The inconvenience of adjusting the gas density in the traditional transmission pipeline may lead to insufficient mixing of the fuel and air, thereby reducing the combustion efficiency. The reduction in combustion efficiency will lead to fuel waste and increased energy consumption.
[0004] Therefore, in order to solve the above problems, we need to propose a combustion head for a multi-stage full premixed burner. Utility Model Content

[0023] It should be noted that: first, the staff can rotate the twist block 901, and the twist block 901 will drive the threaded sleeve 903 to move through the screw rod 902, and the threaded sleeve 903 will drive the adjustment plate 904 to move upward. Since the sealing block 907 on the surface of the adjustment plate 904 is in contact with the baffle 10, when the sealing block 907 moves upward, it will block the flow holes on the surface of the baffle 10 to reduce the flow rate of the gas in the flow holes, and also reduce the flow density of the gas. By setting the sliding sleeve 905 and the sliding rod 906, the adjustment plate 904 is limited, and by setting the sealing block 907, the flow rate and density of the gas are adjusted.
