Gas Burner Distribution Part With Elongated Inlet for Uniform Flames
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas burners for stoves often exhibit uneven flame sizes due to non-circular designs, leading to inconsistent flame distribution across the burner surface.
Innovation Solution
A distribution part for gas burners featuring an elongated passage that follows the shape of the outer wall, ensuring vertically oriented flow paths from a central inlet to outlet ports, thereby balancing volumetric flow rates and enhancing flame uniformity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a central distribution inlet is used in conventional burners, then the structure is simple, but the flame distribution becomes uneven due to varying flow path lengths
Solution Approach 1:
The distribution inlet is segmented into multiple elongated passages distributed across the burner surface, each serving a specific region. This segmentation equalizes flow path lengths from different inlet points to their respective outlet ports, ensuring uniform flame distribution while maintaining structural simplicity
Solution Approach 2:
The distribution inlet transitions from a single central point (0D) to an elongated passage system (1D/2D structure) that extends toward the outlet ports. This dimensional change allows multiple flow paths of equal length to be created, balancing volumetric flow rates across all outlets and achieving homogeneous flame patterns
2Ease of manufacture
If outlet ports are equally spaced in non-circular burners, then the design is simple, but flame sizes differ due to varying distances from the distribution inlet
Solution Approach 1:
Each region of the burner is served by its own elongated passage segment, creating locally optimized flow paths. The passage length and orientation are tailored to each specific region's geometry, ensuring that local flame sizes are uniform even though the overall burner shape is non-circular and outlet ports are equally spaced
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution results in improved flame distribution and reduced flow losses, resulting in a more homogeneous flame pattern and increased energy output.
Implementation Method 1
the gas or gas mixture mainly distributes within the elongated passage or passages forming the distribution inlet. Since the at least one elongated passage follows the shape of the outer wall, respective flow paths from the distribution inlet to the outlet ports are mainly vertically oriented. In other words, the differences in flow length due to different distances from a common distribution inlet are removed. Thus, volumetric flow rates are balanced between the outlet ports.
