Stacked Gas Burner Air Path for Higher Upper Burner Output
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Typical stack-type gas burners face challenges in supplying sufficient secondary air to the upper burner, limiting its output and resulting in reduced overall burner performance.
Innovation Solution
A gas burner apparatus with a support plate and secondary air supply flow path between two vertically stacked burners, ensuring adequate secondary air supply to the upper burner while minimizing the output of the lower burner for efficient simmering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a typical stack-type gas burner receives secondary air from the periphery of flame above the cook top, then the structure is simple, but the upper burner cannot receive sufficient secondary air and its output is limited
Solution Approach 1:
The patent introduces a secondary air supply flow path from the lower side of the support plate, changing the traditional direction of secondary air supply from above to below. This dimensional change allows the upper burner to receive sufficient secondary air from the lower region, resolving the contradiction between maintaining simple structure and increasing upper burner output.
Solution Approach 2:
The patent segments the secondary air supply into two distinct paths: one for the lower burner and another specifically for the upper burner through the support plate. This segmentation allows independent optimization of air supply to each burner, enabling the upper burner to receive adequate secondary air without complicating the overall structure.
2Power
If the through hole of the support plate is spaced apart from the mixture gas supply pipe, then secondary air flow path is formed, but the structure becomes more complex
Solution Approach 1:
The support plate serves multiple functions: it supports the lower burner, provides a pathway for secondary air to reach the upper burner, and its through hole spacing automatically forms the secondary air flow path. This multi-functionality reduces the need for additional components, resolving the contradiction between achieving sufficient secondary air supply and maintaining simple structure.
