Dual-Burner Gas Burner for a Wider Stable Power Range
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gas burners have a limited power range, making it difficult to achieve both high and low power settings efficiently, as the maximum and minimum power are interdependent, resulting in a narrow operational range.
Innovation Solution
A dual-burner system comprising a low power burner unit and a high power burner unit, each with independent gas inlets, injectors, and venturi pipes, with the high power unit's flames being ignited by the low power unit to ensure uniform combustion and a wider power range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single burner unit is used, then the device complexity is reduced, but the power range is limited
Solution Approach 1:
The burner system is segmented into two specialized burner units with different outlet passage configurations. The first burner unit has smaller outlet passages suitable for low power operation, while the second burner unit has larger outlet passages for high power operation. This segmentation enables a wide power range while maintaining relatively simple individual unit structures.
Solution Approach 2:
The burner system achieves multi-functionality by combining two burner units that can operate independently or together. The system can function at low power using only the first burner unit, at high power using only the second burner unit, or at intermediate power levels by operating both units simultaneously, thus providing universal adaptability across a wide power range.
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 dual-burner system allows for a doubled power range compared to single-burner systems, enabling efficient operation at both high and low power settings while maintaining stable combustion and preventing flame lift.
Implementation Method 1
a mixing device, e.g. in the form of a venturi pipe, for mixing the supplied gas with ambient air
Implementation Method 2
a spark plug for igniting the air/gas-mixture leaving the flame crown
Implementation Method 3
releasing the air/gas-mixture for subsequent combustion
