Swirling Flame Gas Burner Layout for Lower Heat Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gas burners often result in inefficient heat transfer and increased risk of burns due to outwardly directed flames, and they may not be resistant to spillage or aesthetically pleasing, with complex designs that complicate removal and reinstallation.
Innovation Solution
A gas burner design featuring inwardly and upwardly directed fuel exit ports within a combustion chamber, secured by a bracket system allowing for easy removal and reorientation, with secondary air inlets for enhanced combustion and a smooth, uninterrupted surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional gas burners use outwardly directed flames, then the flame is visible and provides heating, but heat loss around the exterior of cookware increases and burn risk to users increases
Solution Approach 1:
The patent inverts the conventional flame direction by directing flames inwardly toward the center of the burner rather than outwardly. The fuel exit ports are angled to direct flames inwardly and upwardly, creating a swirling flame pattern that concentrates heat under the cookware and reduces heat loss to the surrounding environment, while also reducing burn risk to users.
Solution Approach 2:
The patent changes the angular parameter of the fuel exit ports to achieve the desired flame direction. The ports are specifically angled to direct flames inwardly and upwardly, creating a controlled swirling flame pattern that optimizes heat transfer efficiency and safety.
2Reliability
If conventional gas burners have complex designs for securing burners, then the burner can be secured to the cooktop, but removal and reinstallation becomes complicated and time-consuming
Solution Approach 1:
The patent segments the burner assembly into a burner body and a separate gas injector that remain connected during removal. The burner can be detached from the cooktop as a unit while the gas injector stays in place, simplifying the removal and reinstallation process while maintaining secure operation.
Solution Approach 2:
The gas injector is extracted from the burner assembly, allowing the burner to be removed and reinstalled independently without disconnecting the gas supply components. This separation simplifies maintenance and replacement procedures.
3Ease of operation
If conventional gas burners have openings or holes facing the top for cookware placement, then cookware can be positioned on the burner, but spillage resistance is reduced and aesthetics are compromised
Solution Approach 1:
The patent inverts the conventional approach by positioning fuel exit ports on the circumferential wall rather than having openings on the top surface. This inwardly directed configuration eliminates top-facing openings that would allow spillage, while still providing effective heating through the inwardly directed swirling flames.
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 design achieves efficient heat transfer with reduced heat loss and burn risk, improved aesthetics, and resistance to spillage, while allowing for easy burner replacement without disconnecting the gas injector.
Implementation Method 1
A plurality of fuel exit ports are disposed in the circumferential wall. The ports are directed generally inwardly toward the combustion chamber and upwardly from the bottom of the combustion chamber
Implementation Method 2
A plurality of secondary air inlets extend through the bottom of the combustion chamber

AI summary
A gas burner having a combustion chamber with a bottom and a circumferential wall. A plurality of fuel exit ports are disposed in the circumferential wall, and are directed generally inwardly toward the combustion chamber and upwardly from the bottom of the combustion chamber. The fuel exit ports are preferably directed inwardly at an angle that is slightly rotated from a central axis of the burner to create a swirling flame. A plurality of secondary air inlets extend through the bottom of the combustion chamber. An injector orifice is aligned with the central axis of the burner. The injector orifice is secured to the cooktop using a bracket, which has an orifice-securing surface, with two sidewalls extending therefrom and terminating in fastening flanges. The fastening flanges have asymmetrically arranged slots therein to receive tabs extending from the burner to ensure proper alignment of the burner and the injector orifice.
