Cross-Flame Burner Layout for Even Heat Without Flare-Ups
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Under-fired broiling appliances face issues with combustible oils and juices draining onto burners, causing blockages and uncontrolled flare-ups, and uneven heat distribution, leading to incomplete cooking and safety concerns.
Innovation Solution
A cross-flame burner system with arched extensions and a Venturi body, combined with a radiant tray design that prevents oil pooling and enhances air supply for even combustion, ensuring burner ports remain clear and heat is evenly distributed across the grilling surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a radiant tray is used to conduct heat from burner flames, then heat transmission efficiency is improved, but combustible oils and juices can pool on the radiant surface causing uncontrolled flare-ups
Solution Approach 1:
The radiant tray employs a curved, arched surface design instead of a flat surface. This curvature prevents combustible oils and juices from pooling on the radiant surface, eliminating the condition for uncontrolled flare-ups while maintaining effective heat conduction from the burner flames to the cooking area
2Use of energy by moving object
If burner ports are exposed to allow flames to reach the radiant surface, then heat transmission is improved, but burner ports become blocked by falling debris and oils
Solution Approach 1:
The radiant tray serves as an intermediary component positioned between the burner ports and the cooking area. It receives heat from the burner flames and conducts it forward, allowing the burner ports to remain protected while still achieving effective heat transmission to the cooking surface
3Temperature
If traditional burners are used to heat the grilling surface, then heating function is provided, but heat distribution is uneven creating hot and cold spots
Solution Approach 1:
The burner system is divided into multiple segments or zones along the burner assembly. This segmentation allows for distributed flame sources that collectively provide uniform heat distribution across the entire grilling surface, eliminating hot and cold spots while maintaining effective heating
