Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-flame burners face challenges in achieving reliable and safe ignition of all burner nozzles, especially in automated operations, leading to potential unburned fuel gases and explosion risks due to incomplete combustion.
Innovation Solution
The design incorporates secondary nozzle openings arranged linearly or at an angle to the main nozzle arrangement, allowing for the generation of secondary flames that can transmit ignition to adjacent burner nozzles, ensuring complete and reliable ignition without the need for direct alignment with a workpiece.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual ignition method is used for multi-flame burners, then ignition can be achieved, but the operation complexity increases and safety decreases due to manual alignment requirements
Solution Approach 1:
The burner system performs ignition automatically through the flame transmission mechanism between adjacent burners, eliminating the need for manual ignition operations. The system self-ignites by transmitting flame from the first ignited burner to subsequent burners through the specifically designed flame transmission channels.
2Ease of operation
If automated ignition is implemented, then operation simplicity improves, but ignition reliability deteriorates due to alignment sensitivity
Solution Approach 1:
The burner design incorporates pre-configured flame transmission channels and geometric arrangements that ensure proper flame propagation paths are established before ignition occurs. The spatial arrangement of burners and flame channels is predetermined to guarantee reliable flame transmission from the first burner to subsequent burners without requiring precise manual alignment during operation.
3Reliability
If flame transmission between burners is improved, then ignition reliability increases, but device complexity increases due to additional structural components
Solution Approach 1:
The flame transmission function is integrated into the existing burner structure through shared combustion chambers and interconnected flame channels. Instead of adding separate ignition devices for each burner, the design merges the ignition and flame propagation functions into the overall burner assembly, using the combustion products and flame paths of one burner to serve the ignition needs of adjacent burners.
4Productivity
If manual alignment with workpiece is required, then flame directionality is maintained, but productivity decreases due to manual intervention
Solution Approach 1:
The manual mechanical alignment operation is replaced by an automated flame transmission mechanism that inherently directs flame toward adjacent burners and the workpiece. The geometric design of flame channels and burner arrangement automatically ensures proper flame direction without requiring manual positioning or alignment operations by the operator.
