Burner Fitting Member Aligns Thrust Direction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing insertion/retraction mechanisms for burners in gasifiers often experience stress due to bending moments and deflection issues, particularly when the thrust direction of driving cylinders does not align with the longitudinal axis of the burner, leading to inaccurate positioning and reduced performance in slag melting.
Innovation Solution
A burner system with parallel driving cylinders connected by a connecting member and a fitting member that constrains axial movement while allowing perpendicular movement, ensuring the thrust direction aligns with the burner's axis, reducing deflection and improving positioning accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the thrust direction of driving cylinders does not align with the longitudinal axis of the burner, then the burner can be installed with flexibility, but stress caused by bending moment is generated and positioning accuracy deteriorates
Solution Approach 1:
A thrust direction adjusting mechanism is introduced as an intermediary component between the driving cylinder and the burner main body. This mechanism includes a thrust direction adjusting member that can rotate relative to the burner main body, allowing independent adjustment of the thrust direction from the burner's longitudinal axis. The mechanism transmits the driving force while enabling angular adjustment, thus resolving the contradiction between installation flexibility and positioning accuracy.
2Ease of operation
If multiple driving cylinders are provided to move the burner main body, then the moving capability is enhanced, but the cylinders may not be synchronized and thrust direction deflects
Solution Approach 1:
Multiple driving cylinders are merged into a single integrated driving system that controls the rotation of the thrust direction adjusting member. Instead of having independent cylinders for axial and radial movement, the invention combines their functions into one rotational degree of freedom for the adjusting member, while the axial movement is controlled separately. This reduces synchronization issues by consolidating the complex multi-cylinder control into a more manageable system.
3Length of moving object
If the burner main body is made long to reach the gasifier wall, then the insertion depth is sufficient, but error displacement of the distal end position becomes larger
Solution Approach 1:
The thrust direction adjusting member acts as an intermediary that decouples the long burner main body from the driving cylinders. By allowing angular adjustment at the connection point, the mechanism compensates for small angular deviations that would be magnified over the long length of the burner. This enables the distal end to maintain high positioning accuracy despite the long insertion depth required to reach the gasifier wall.
