Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Metallurgical treatment rooms experience uneven heat distribution due to uneven exposure to flames from existing burners or lances, which is particularly problematic in treatment rooms with unusual geometries.
Innovation Solution
A device with fluidly separated supply channels for the second combustion medium, allowing for individual flow rate adjustment and control, enabling precise manipulation of flame geometry and direction through motor-operated or solenoid valves, and optionally using flow separators to create multiple channels for two- or three-dimensional flame positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single supply line for the second combustion medium is used, then the device structure is simple, but the flame geometry and direction cannot be controlled
Solution Approach 1:
The single supply line for the second combustion medium is divided into multiple separate supply lines (at least two), each capable of independent flow rate adjustment. This segmentation enables control over flame geometry and direction by varying the flow distribution among the separate lines, while keeping each individual line relatively simple in structure.
2Manufacturing precision
If multiple supply channels are used to control flame position, then flame distribution uniformity is improved, but the device complexity increases
Solution Approach 1:
The supply system is segmented into multiple independent supply channels with individual flow control, allowing precise adjustment of flame position and shape to achieve uniform heat distribution across the treatment room.
Solution Approach 2:
The supply channels are equipped with adjustable flow control elements (such as valves or variable geometry components) that allow dynamic adjustment of flow rates during operation. This enables the flame geometry and position to be optimized for different treatment room geometries and heat distribution requirements.

AI summary
Burners are known in which fuel and oxidizer are injected into a metallurgical treatment chamber via separate feeds and combusted there in a flame. A disadvantage is that treatment chambers, especially those with unusual geometries, are exposed to the flame very unevenly, resulting in a highly uneven heat distribution within the treatment chamber. According to the invention, at least one of the injected combustion media – fuel or oxidizer – is introduced into the treatment chamber via several flow-separated feeds. The flow rate through each feed can be adjusted separately. By appropriately selecting the number of feeds and the flow rates, the flame can be moved in different directions during the treatment, in particular pivoted or rotated.
