1Reliability
If a conventional burner device is used for combustion, then the combustion process is simple and device complexity is low, but incomplete combustion occurs generating carbon monoxide
Solution Approach 1:
A catalyst device is introduced as an intermediary component between the combustion chamber and the external environment. This catalyst device contains a catalyst that facilitates the conversion of carbon monoxide to carbon dioxide, thereby ensuring complete combustion without significantly complicating the overall burner structure. The catalyst acts as a mediator that enables the chemical transformation needed for complete combustion.
Solution Approach 2:
The catalyst device is nested within the burner frame structure. The burner frame includes a first frame and a second frame extending from the first frame, with the catalyst device disposed on the second frame. This nested arrangement integrates the catalyst functionality into the existing burner structure without requiring a completely separate system, thus improving combustion completeness while controlling device complexity.
2Productivity
If a catalyst device is added to convert carbon monoxide, then combustion efficiency improves, but device complexity increases
Solution Approach 1:
The catalyst device is nested within the burner frame structure. The burner frame includes a first frame and a second frame extending from the first frame, with the catalyst device disposed on the second frame. This nested arrangement integrates the catalyst functionality into the existing burner structure without requiring a completely separate system, thus improving combustion efficiency while controlling device complexity.
Solution Approach 2:
The catalyst device is positioned at a specific location within the exhaust passage where carbon monoxide concentration is highest. The burner frame structure is designed to guide exhaust gases through the catalyst device, ensuring that the catalyst operates at the most effective location. This localized approach maximizes combustion efficiency improvement while minimizing the overall device complexity increase.
3Speed
If the burner frame minimizes flow resistance, then gas flow improves, but structural complexity increases
Solution Approach 1:
The burner frame is segmented into a first frame and a second frame extending from the first frame. This segmentation allows for optimized gas flow paths at different stages of combustion. The first frame handles the initial combustion phase while the second frame directs gases through the catalyst device, minimizing flow resistance through strategic structural division rather than a single complex structure.
Solution Approach 2:
The second frame extends in a direction substantially perpendicular to the longitudinal direction of the first frame, creating a three-dimensional gas flow path. This dimensional change allows exhaust gases to flow through the catalyst device without creating excessive resistance, as the perpendicular extension provides an additional flow dimension that reduces congestion and improves overall gas flow rate.
