Gas Burner Separating Element for Turbulence Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Atmospheric gas burners face reduced efficiency due to turbulence and light leakages in the fuel mixture caused by overlapping ducts, leading to incomplete mixing and reduced combustion efficiency.
Innovation Solution
A tightly constrained separating element, preferably a flat plate made of steel or aluminum, is used to prevent leakages between the fuel mixture and primary air ducts, reducing turbulence and ensuring a tight fluidic connection between the mixing and distribution chambers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If overlapping ducts are used for transferring fuel mixture and primary air, then the mould shape becomes geometrically simple, but turbulence and light leakages occur reducing burner efficiency
Solution Approach 1:
A separating element is introduced as an intermediary component between the fuel mixture transferring duct and the primary air inflow duct. This separating element prevents direct interaction between the two fluid streams, eliminating turbulence and light leakages while maintaining the geometric simplicity of the overall burner structure.
2Ease of manufacture
If a flat separating element is disposed between ducts, then manufacturing is simplified, but fuel mixture leakages occur in the overlapping duct structure
Solution Approach 1:
The separating element extends in the radial dimension between the concentric ducts, creating a three-dimensional barrier that prevents fuel mixture leakages. This radial extension maintains the flat plate manufacturing simplicity while adding the necessary dimensional coverage to seal the overlapping duct structure.
3Ease of operation
If separating element is not tightly constrained, then assembly is easier, but light leakages and turbulence increase reducing combustion efficiency
Solution Approach 1:
The constraining function is extracted as a separate feature on the separating element itself, rather than relying on the fit between multiple components. This allows the separating element to be easily assembled while ensuring tight constraints that prevent light leakages and turbulence.

Function Achieved in This Case
The solution significantly enhances combustion efficiency by minimizing leakages and turbulence, resulting in a highly efficient burner operation while maintaining the geometric simplicity of the burner head and cup.
Implementation Method 1
the efficiency of such a burner is somewhat reduced because of the turbulences that are created along the path followed by the fuel mixture inside the burner
