Solution Overview
Problem
Existing burners used in household appliances, such as water heaters, face issues with insecure installation, inadequate fuel ejection, and low combustion heat intensity, leading to excessive nitrogen oxide emissions.
Innovation Solution
A burner design featuring multiple parallel flame distributors connected by a fastener with a compressing piece, a gas distribution device, and a U-shaped cooling water pipe, which enhances stability, combustion intensity, and reduces nitrogen oxide emissions through secure installation and efficient gas mixing and cooling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional burner structure is used, then the device complexity is low, but the installation security is insufficient and combustion intensity is inadequate
Solution Approach 1:
The burner is divided into multiple independent flame distributors (at least three), each with its own ejection tubes and gas distribution channels. This segmentation allows each module to be independently secured and positioned, improving overall installation security while maintaining manageable structural complexity through modular design
Solution Approach 2:
Multiple flame distributors are combined into a single integrated burner assembly that works together as one system. The fasteners and side plates merge the individual flame distributors into a unified structure, achieving secure installation while the combined structure enhances combustion intensity through coordinated fuel ejection from multiple points
2Power
If fuel ejection is increased to improve combustion intensity, then combustion heat intensity improves, but nitrogen oxide emissions increase
Solution Approach 1:
The fuel ejection is segmented into multiple separate ejection tubes distributed across at least three flame distributors. This distributes the combustion load across multiple smaller combustion zones rather than one large high-temperature zone, reducing peak temperatures that generate nitrogen oxides while maintaining total combustion heat intensity
Solution Approach 2:
Each ejection tube is designed with specific local characteristics for fuel distribution, and the side plates provide localized cooling zones near the ejection points. This local quality control allows optimized combustion at each point while managing overall temperature distribution to reduce nitrogen oxide formation
3Power
If multiple flame distributors are used to increase combustion intensity, then combustion heat intensity improves, but the device complexity increases
Solution Approach 1:
The burner is segmented into multiple identical or similar flame distributor modules, each with standardized ejection tubes and mounting features. This modular segmentation increases combustion intensity through multiple fuel sources while controlling complexity through repetition of proven design units
Solution Approach 2:
Multiple flame distributors are merged into a single integrated assembly using common side plates and fasteners. This merging approach achieves high combustion intensity through coordinated multi-point fuel ejection while managing complexity by using unified mounting structures and standardized connection methods across all modules
