Burner Gas Distribution Structure for Stable Oxidant Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas distribution components for burners in metallurgical or glass industrial melting furnaces face high operation difficulty and cost due to complex regulating valves, and require frequent adjustments in oxidant flow rates, especially in conditions where precise regulation is not necessary.
Innovation Solution
A gas distribution component with a diffusion/buffering chamber and non-uniformly distributed through-holes, along with baffles at the junctions, controls oxidant flow speed and distribution, eliminating the need for complex valves, and allowing easy operation and adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a complex regulating valve structure is used to control oxidant flow rate, then the precision of oxidant flow regulation is improved, but the operation difficulty and cost increase
Solution Approach 1:
The gas distribution component uses a self-regulating structure where the diffusion/buffering chamber and through-holes automatically control oxidant flow distribution without requiring external regulating valves. The system serves itself by using the chamber volume and hole geometry to inherently manage flow rates, eliminating the need for complex manual or automated valve systems.
Solution Approach 2:
The patent extracts and removes the complex regulating valve from the system entirely. Instead of using a valve to control oxidant flow, the design takes out the valuation function and integrates it directly into the chamber and hole structure, simplifying the overall system while maintaining flow control capability.
2Measurement precision
If a complex regulating valve structure is used to control oxidant flow rate, then the precision of oxidant flow regulation is improved, but the manufacturing cost increases
Solution Approach 1:
The patent extracts and removes the complex regulating valve from the system entirely. Instead of using a valve to control oxidant flow, the design takes out the valuation function and integrates it directly into the chamber and hole structure, simplifying the overall system while maintaining flow control capability.
Solution Approach 2:
The gas distribution component uses simple, easily manufacturable structures (chamber with holes) instead of expensive, complex valve mechanisms. The design prioritizes low-cost materials and fabrication methods, accepting that the component may need replacement or adjustment rather than using durable, expensive valve systems.
3Ease of operation
If multiple through-holes with non-uniform diameters are used in the oxidant inlet channel, then the oxidant flow distribution is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The patent applies local quality by creating non-uniform through-holes with different diameters at different locations in the oxidant inlet channel. This local variation in hole size is strategically designed to achieve uniform oxidant distribution across the diffusion chamber, compensating for natural flow patterns and ensuring each region receives appropriate oxidant flow.
4Loss of energy
If the diffusion/buffering chamber volume is increased to reduce oxidant flow speed, then the pressure loss is reduced, but the device volume increases
Solution Approach 1:
The patent uses parameter changes by optimizing the chamber volume and through-hole dimensions to achieve the desired flow reduction and pressure loss minimization. By carefully selecting specific parameter values (chamber volume, hole diameters, hole locations), the system achieves efficient oxidant distribution without requiring excessive chamber size.
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 component achieves stable oxidant flow and reduced pressure loss, enabling efficient oxidant distribution with lower manufacturing and operation costs, and adapts to varying fuel and oxidant conditions without complex valve structures.
Implementation Method 1
a diffusion/buffering chamber providing a space for diffusion of the oxidant after the oxidant flows out of the oxidant inlet channel
Implementation Method 2
multiple through-holes are provided in a wall of the oxidant inlet channel that is adjacent to the diffusion/buffering chamber
Implementation Method 3
a baffle may be provided at a junction of the diffusion/buffering chamber and each oxidant delivery component, the baffle partially blocking an inlet of the oxidant delivery component. These baffles can limit the flow rate of oxidant conveyed to each oxidant delivery component
