Description

Technical Field

[0001] This utility model belongs to the field of combustion equipment technology, and more specifically, it relates to a hydrogen burner. Background Technology

[0002] Existing hydrogen burners have several issues regarding combustion efficiency and safety. For example, traditional burners are prone to flame instability due to uneven mixing during combustion, and are susceptible to backfire under high pressure, posing safety hazards. Furthermore, improper nozzle design in traditional burners can lead to localized uneven gas mixing, air-fuel ratio mismatch, and flame instability, resulting in incomplete combustion and energy waste. Therefore, a new type of hydrogen burner is needed to improve combustion efficiency and safety. Summary of the Invention

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention provides a hydrogen burner designed to improve the efficiency and safety of hydrogen combustion.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a hydrogen burner, comprising: a burner head, comprising: a base, which is cylindrical and has a combustion chamber internally; and a nozzle, disposed at a first end of the base and connected to the combustion chamber; an igniter, wherein a plurality of igniters are disposed on the base between the nozzles; a feed pipe, wherein a plurality of feed pipes are disposed circumferentially along the base and connected to the combustion chamber for supplying hydrogen into the combustion chamber; and a gas supply unit, connected to a second end of the base via an air supply pipe for supplying air into the combustion chamber.

[0005] Preferably, the air supply unit includes a closed outer casing, an air supply cavity is constructed inside the outer casing, an impeller is disposed inside the air supply cavity, and a motor for driving the impeller to rotate is disposed outside the outer casing.

[0006] Preferably, the outer casing is provided with an air volume control mechanism that communicates with the air supply cavity, and the air inlet of the air volume control mechanism is provided with an adjustable damper.

[0007] Preferably, the plurality of nozzles are distributed in a lotus root shape on the substrate.

[0008] Preferably, a plurality of the igniters are embedded in the first end of the substrate and are arranged alternately with the nozzle.

[0009] Preferably, the air supply pipe is detachably connected to the base via a flange, and a double-layer graphite sealing ring is provided at the flange interface.

[0010] This utility model has the following advantages due to the adoption of the above technical solution:

[0011] 1. High-efficiency combustion: By optimizing the design of the burner head and feed pipe, the nozzles of the burner head are distributed in the first section of the substrate in the shape of turbine blades and connected to the internal combustion chamber of the substrate. The feed pipe is arranged around the circumference of the substrate to deliver hydrogen, ensuring that hydrogen and air are fully mixed and improving combustion efficiency.

[0012] 2. High safety: The design of the burner head and the configuration of the igniter are different from traditional premixing methods, which effectively reduces the propagation speed of the hydrogen flame and improves the flame stability, thereby effectively preventing flame detachment and backfire, and improving the safety of the combustion process.

[0013] 3. Flexible adjustment: The air volume control mechanism of the gas supply unit can adjust the size of the damper to adapt to different combustion needs, thereby improving the stability and flexibility of combustion.
