Multi-Zone Surface Burner With Independent Flame Matrix Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing burners with surface combustion require significant installation space and have inefficient heat generation due to uniform air supply and complex structural designs, limiting their ability to achieve high heat output and efficient control.
Innovation Solution
A multi-zone burner design where each burner zone is supplied with a separate fuel-air mixture, with flame matrices aligned in the same direction, allowing for flat and compact arrangement, and independent control of each zone, along with a common blower and control flaps for efficient fuel-air mixture distribution, enabling increased combustion efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a common blower supplies fuel-air mixture to all burner zones uniformly, then the device complexity is reduced, but the combustion efficiency and heat output are insufficient
Solution Approach 1:
The burner system segments the fuel-air mixture supply into separate controllable zones. Each burner zone has its own control flap that can independently regulate the fuel-air mixture flow, allowing differentiated control of combustion in each zone while maintaining a single common blower. This segmentation enables optimized combustion efficiency and higher heat output without requiring multiple blowers.
2Device complexity
If burner zones are arranged with deep installation depth, then each zone can be structurally simple, but the installation space becomes large
Solution Approach 1:
The burner zones are arranged in a horizontally extended configuration rather than vertically stacked. The flame matrices of adjacent burner zones are aligned in the same direction, allowing the zones to be positioned side-by-side in a planar arrangement. This dimensional change from vertical to horizontal layout reduces the installation depth while maintaining structural simplicity of each individual burner zone.
3Adaptability or versatility
If flame matrices are inclined in different directions for each burner zone, then each zone can be independently optimized, but the overall combustion efficiency decreases
Solution Approach 1:
While maintaining the ability to independently control each burner zone through separate control flaps, the flame matrices of all burner zones are oriented in the same direction. This uniform orientation ensures that combustion products from adjacent zones mix efficiently and contribute to overall heat generation, maximizing combustion efficiency. The local control capability is preserved through independent fuel-air mixture regulation, while the global orientation optimizes energy utilization.

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 solution allows for a compact, high-heat-output burner with efficient control and increased combustion efficiency, as each burner zone can be independently controlled, and the flame matrix is aligned to maximize heat generation without inclination, resulting in a homogeneous flame matrix across zones.
