Description

Technical Field

[0001] This utility model relates to the field of burners, and in particular to a wall-mounted hot water boiler burner. Background Technology

[0002] Traditional wall-mounted water heater burners generally employ a single burner hole structure or a simple combination of burner hole layouts, which easily leads to problems such as uneven gas-air mixing, concentrated flame distribution, and significant localized high-temperature zones. This design is prone to incomplete combustion, increasing emissions of harmful gases such as CO. Furthermore, due to the single flame propagation path, there is a risk of delayed ignition or flameout between adjacent burner holes. Especially under high-load conditions, flame stability decreases, and thermal efficiency is significantly reduced, making it difficult to meet energy-saving and environmental protection requirements. Utility Model Content

[0003] The purpose of this invention is to provide a wall-mounted hot water boiler burner to solve the above-mentioned problems.

[0004] According to one aspect of the present invention, a wall-mounted hot water boiler burner is provided, comprising: a cylindrical burner body and an air inlet pipe connected to the lower part of the burner body; the burner body is provided with a plurality of strip-shaped fire hole modules spaced apart circumferentially, a circular fire hole module is provided directly below each strip-shaped fire hole module, and an ignition transfer hole module is provided between the top ends of adjacent strip-shaped fire hole modules.

[0005] In some embodiments, each of the strip-shaped flame hole modules includes five sets of axially arranged strip-shaped flame hole units, and each strip-shaped flame hole unit includes four circumferentially distributed strip-shaped flame holes.

[0006] In some embodiments, each of the circular fire hole modules includes two sets of axially arranged circular fire hole units, and each of the circular fire hole units includes four circumferentially distributed circular fire holes.

[0007] In some embodiments, each of the ignition transfer hole modules includes two sets of axially arranged ignition transfer hole units, and each of the ignition transfer hole units includes six circumferentially distributed ignition transfer holes.

[0008] In some embodiments, each of the strip-shaped flame holes has a square hole structure, and the size of each strip-shaped flame hole is 6mm × 0.4mm.

[0009] In some embodiments, the diameter of each of the circular fire holes is 0.5 mm.

[0010] In some embodiments, the diameter of each of the ignition transfer holes is 0.5 mm.

[0011] In some embodiments, a fixed support frame is welded to both the outside of the burner body and the outside of the air inlet pipe.

[0012] In some embodiments, the cross-sectional diameter of the burner body is 50±1mm.

[0013] This invention significantly optimizes combustion performance through a three-stage flame hole coordinated layout:

[0014] 1. Improved flame uniformity: The circumferentially spaced strip-shaped flame hole modules form the main flame band, which, together with the circular flame hole modules directly below it, constitutes a double-layer flame structure, allowing the gas to spread evenly on the burner surface, avoiding local high-temperature zones and improving thermal efficiency.

[0015] 2. Enhanced ignition reliability: The ignition transfer hole module set between the tops of adjacent strip-shaped flame hole modules enables instantaneous cross-zone flame transfer through dense multi-hole distribution, eliminating ignition blind spots and ensuring continuous and stable flame combustion under high load.

[0016] 3. Improved combustion completeness: The narrow slit structure of the strip-shaped burner holes enhances the gas jet velocity, while the circular burner holes enhance secondary air entrainment and promote gas-air premixing, resulting in more complete combustion and reduced CO emissions;

[0017] 4. Enhanced structural adaptability: The modular fire hole design matches the cylindrical burner body, adapting to the limited space of the wall-hung boiler, while the fixed support frame ensures the overall structural rigidity and extends service life. Attached Figure Description
