Burner Group With Nested Flame Circles For Balanced Heating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional burner groups with single circular flames inadequately heat cooking vessels, particularly woks, as they only effectively warm the edges, leading to inefficient energy transfer and higher emissions of harmful gases like CO and NOx.
Innovation Solution
A burner group design featuring an inner and outer mixing chamber with vertical and horizontal injectors, respectively, and Venturi channels that create non-intersecting flame circles of different diameters, allowing for balanced heating of a wider cooking vessel surface through a homogeneous gas-air mixture, enhanced by an air duct for complete combustion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single circular flame is used in conventional burners, then the structure is simple, but only the edges of the cooking vessel can be heated effectively
Solution Approach 1:
The burner is divided into multiple independent flame circles (inner flame circle, first outer flame circle, second outer flame circle) with different diameters. Each flame circle is fed by separate gas supply channels and mixing chambers, allowing them to operate independently and heat different regions of the cooking vessel simultaneously, thus resolving the contradiction between heating effectiveness and structural simplicity.
Solution Approach 2:
The invention transitions from a single-plane circular flame to a multi-plane stepped flame structure. The inner flame circle and outer flame circles are arranged at different vertical levels (stepped arrangement), creating a three-dimensional flame pattern that can contact both edges and center of the cooking vessel, effectively adding a vertical dimension to the heating pattern.
2Area of stationary object
If multiple flame circles are introduced to heat both edges and center of the vessel, then heating coverage is improved, but the device structure becomes more complex
Solution Approach 1:
Multiple flame circles and their associated gas supply systems are merged into a single integrated burner body. The inner mixing chamber, first outer mixing chamber, and second outer mixing chamber are all incorporated into one burner structure with coordinated gas channels, reducing the need for separate components and simplifying the overall device while maintaining multi-zone heating capability.
Solution Approach 2:
The flame circles are arranged in a nested concentric pattern with the inner flame circle surrounded by the first outer flame circle, which is in turn surrounded by the second outer flame circle. This nested arrangement maximizes heating coverage within a compact burner footprint, increasing the effective heating area without proportionally increasing device complexity.
3Use of energy by moving object
If flames are arranged to contact both edges and center of the pot, then energy transfer efficiency is improved, but harmful gas emissions increase
Solution Approach 1:
The invention optimizes the diameter and vertical position parameters of each flame circle to achieve complete combustion. The inner flame circle has a smaller diameter while outer flame circles have progressively larger diameters, with each positioned at specific heights to ensure proper mixing of gas and air. This parameter optimization allows efficient energy transfer to the cooking vessel while maintaining complete combustion to minimize CO and NOx emissions.
