Combustion Heater Flame Stabilization via Segmented Chamber
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing combustion heaters face limitations in design flexibility and thermal efficiency due to the need for the combustion chamber to be close to the outer wall for flame stabilization, which restricts the arrangement and leads to heat dissipation, reducing efficiency.
Innovation Solution
A combustion heating system with a premixed-type design featuring a placement plate, outer wall, partitioning plate, and heating plate configuration, including a flame-stabilization portion with a concavity, linking portions, and a lead-in and lead-out portion arrangement that allows for increased freedom in combustion chamber placement and heat transfer, enabling efficient preheating of fuel gas and stabilization of the flame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the combustion chamber is brought close to the outer wall for flame stabilization, then the flame is stabilized by collision with the outer wall, but the heat dissipation from the combustion chamber to outside increases via the outer wall
Solution Approach 1:
The invention divides the combustion chamber into multiple segments or zones. By segmenting the combustion chamber, the flame can be stabilized in specific zones without requiring the entire combustion chamber to be close to the outer wall, thereby reducing heat dissipation while maintaining flame stability in the necessary regions.
Solution Approach 2:
The invention introduces a new spatial dimension or configuration by adding a reflection plate or modifying the combustion chamber geometry in a different dimensional arrangement. This allows the flame to be stabilized through reflection or alternative geometric constraints rather than direct contact with the outer wall, reducing thermal loss while maintaining stability.
2Loss of energy
If the combustion chamber is spaced apart from the outer wall to inhibit heat dissipation, then thermal efficiency is improved, but the degree of freedom in arrangement is reduced and flame stabilization becomes difficult
Solution Approach 1:
Segmenting the combustion chamber allows different zones to be positioned at different distances from the outer wall. This enables the system to maintain arrangement freedom and adaptability while ensuring that flame stabilization zones are appropriately positioned without compromising thermal efficiency in other regions.
Solution Approach 2:
The invention introduces an intermediary element such as a reflection plate or structural component that mediates between the combustion chamber and the outer wall. This intermediary enables flame stabilization without requiring direct proximity to the outer wall, thus maintaining arrangement freedom while preventing excessive heat dissipation.
3Loss of energy
If the combustion chamber is spaced apart from the outer wall to improve thermal efficiency, then heat dissipation is reduced, but flame stabilization mechanisms become more complex
Solution Approach 1:
The reflection plate serves as a simple intermediary component that provides flame stabilization through geometric reflection rather than complex active control systems. This maintains thermal efficiency by allowing spacing from the outer wall while avoiding complexity through the use of a passive, geometrically-based stabilization mechanism.
Solution Approach 2:
The invention stabilizes the flame by changing geometric parameters such as the angle and position of the reflection plate, rather than introducing complex control systems. This allows flame stabilization to be achieved through simple parameter adjustments, maintaining thermal efficiency without increasing device complexity.

Function Achieved in This Case
This configuration enhances the degree of freedom in arranging the combustion chamber, improves thermal efficiency by reducing heat dissipation, and stabilizes the flame without requiring complex manufacturing processes, while maintaining high radiant efficiency and reducing CO concentration from incomplete combustion.
Implementation Method 1
a constitution is disclosed that is provided with a combustion chamber that comes into contact with the outer wall that is disposed around the outer circumference of the main body, a lead-in portion that guides fuel gas from the center of the main body to the combustion chamber, and a lead-out portion that concentrates post-combustion exhaust gas at the center of the main body and guides it to outside the body
Implementation Method 2
in the combustion chamber, by causing the fuel gas that flows in from the lead-in portion to collide with the outer wall and to be retained, the flame is stabilized
