Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional diffusion flame burning is used, then structure is simple and cost is low, but CO and NOx emission concentration is high
Solution Approach 1:
The burner head is segmented into multiple independent burning holes (e.g., 9 holes arranged in a 3x3 pattern), each acting as an independent diffusion flame source. This segmentation allows the system to maintain the simplicity of diffusion flame burning while reducing overall pollutant emissions through distributed combustion
Solution Approach 2:
Each burning hole is equipped with dedicated primary air holes and secondary air holes, creating localized air-fuel mixing zones with optimized quality. The primary air holes provide pre-mixing while secondary air holes supply additional oxygen at the flame base, ensuring complete combustion locally and reducing CO and NOx emissions
2Object-generated harmful factors
If full-premixed metal fiber surface burning head is used, then CO and NOx emission concentration is low, but cost is high and burner blocking and tempering risks exist
Solution Approach 1:
The invention extracts the air mixing function from the complex metal fiber net structure and implements it through simple circular burning holes with dedicated air holes in the burner head. This extraction maintains low emission characteristics while eliminating the complexity, cost, and reliability issues associated with metal fiber nets
Solution Approach 2:
The burner head uses a simple, inexpensive structure made of common materials that can be easily manufactured and replaced if needed. The design avoids expensive metal fiber nets while achieving similar or better emission performance through optimized hole geometry and air supply
3Object-generated harmful factors
If staged burning head is used, then NOx emission concentration is reduced, but structure is complex, cost is high, and CO emission concentration is high
Solution Approach 1:
The invention merges the primary mixing function (typically separate in staged burners) directly into the burning hole structure itself. Primary air holes are positioned to mix with fuel gas before combustion, while secondary air holes provide additional mixing at the flame base, combining multiple mixing stages in a single integrated structure

AI summary
A burner contains a burner component. The burner component includes a main frame and at least one stable burning isolation strip. An interior of the main frame is divided into at least two ventilation areas by the stable burning isolation strip in a gas channel direction. Several separation mechanisms are arranged in each ventilation area and divide the ventilation area into several through holes distributed in the gas channel direction. The through holes are used for a mixed gas of fuel gas and air to pass through and enhancing a mixing effect of the fuel gas and the air. The flame of a burning surface of the main frame can be divided into independent flames by the stable burning isolation strip so that the burning is more stable and fewer pollutants are emitted.
