Offset Mesh Burner Laminate for Sintering Dust Blockage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Surface combustion burners in industrial settings face frequent passage blocking due to dust adhesion, leading to unstable combustion and increased maintenance needs, as dust from fine powders of iron ores adheres to the burner mat and causes blockages, which existing solutions fail to adequately address.
Innovation Solution
A surface combustion burner design featuring a laminate structure with offset mesh plates, optimized opening ratios, and heat-resistant materials to prevent dust adhesion while maintaining passage integrity, ensuring stable combustion over a longer period.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the passage is widened to prevent dust blocking, then dust passage blocking is reduced, but high-temperature dust enters the burner interior causing flashback
Solution Approach 1:
The passage is segmented into multiple sections with mesh plates positioned at different locations. Each mesh plate acts as an independent barrier, dividing the single passage into multiple segments that collectively prevent dust accumulation while maintaining proper flame containment
Solution Approach 2:
Multiple mesh plates are nested within the passage at different positions, with each mesh plate contained within the burner structure. This nested arrangement allows the mesh plates to work together in a compact configuration, providing multiple barriers against dust while maintaining passage integrity
2Stability of the object's composition
If a burner mat structure is used for surface combustion, then uniform heating is achieved, but dust adhesion causes passage blocking requiring frequent cleaning
Solution Approach 1:
Mesh plates with controlled porosity are used instead of traditional burner mats. The porous structure of the mesh plates allows for gas passage while the rigid mesh construction prevents dust adhesion and accumulation, eliminating the need for frequent cleaning while maintaining combustion stability
Solution Approach 2:
The burner employs a composite structure combining mesh plates made of heat-resistant materials with specific surface properties. This composite design integrates the benefits of uniform heat distribution with dust-resistant characteristics, creating a material system that resists dust adhesion while maintaining thermal performance
