Angled Gas Duct Burner Ring for Uniform Flame Border
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas burner designs often result in an uneven flame border at the ignition transfer slot between the inner and outer circumferences of the burner ring, leading to inefficient combustion.
Innovation Solution
The burner ring features a distribution chamber with gas outlet openings on the outer circumference and an ignition transfer slot that is open on one side, with a gas duct that is symmetrically arranged and angled relative to the ignition transfer slot, and multiple gas supply openings that distribute gas flow evenly, ensuring a uniform flame border.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If gas flow is conducted directly into the transfer ignition slot with lateral offset, then the structure is simple, but the flame border becomes uneven
Solution Approach 1:
The gas supply opening is arranged at an angle to the ignition transfer slot, introducing a dimensional change in the gas flow direction. This angular arrangement causes the gas flow to impinge obliquely on the opposite wall of the gas duct, creating a more even distribution pattern as the gas exits through the transfer slot, thereby resolving the flame border uniformity issue while maintaining structural simplicity
2Device complexity
If gas duct is open on both sides, then gas flow distribution is simple, but exhaust gas concentration and soot formation increase
Solution Approach 1:
The gas duct is closed on the side facing the inner circumference, extracting or removing the harmful effect of unrestricted gas flow. This closure prevents excessive exhaust gas concentration and reduces soot formation by controlling the gas flow path and combustion environment, while the duct remains open on the outer side to allow necessary gas supply
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
This configuration ensures a more even distribution of the gas flow, resulting in a uniform flame border and reduced soot formation, enhancing combustion efficiency and stability.
Implementation Method 1
the oblique impingement of a gas flow introduced into the gas duct on the opposite wall of the gas duct distributes the gas flow relatively evenly and exits through the overignition slot
Implementation Method 2
a spark plug and a thermocouple can be arranged in the interior
