Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current coke oven battery designs do not allow for optimal air and gas flow within the heating wall, leading to undesirable heating characteristics such as loss of heat and increased fluid pressure, and fail to mix gas and air at various elevational levels throughout the oven wall.
Innovation Solution
A flue block with integrated risers that extend past its proximal end, allowing for mixing of air and gas at different elevational levels within the flue, improving air and gas flow, and incorporating features like recesses, protrusions, and grooves to enhance fluid communication and mixing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional flue block design is used, then structural simplicity is maintained, but air and gas flow optimization is achieved
Solution Approach 1:
The flue block is segmented into multiple functional regions including a proximal end, distal end, top surface, and bottom surface. The risers are further segmented into different heights (first riser and second riser) positioned at different elevations within the flue block, allowing independent optimization of gas and air flow at various levels to improve combustion efficiency
Solution Approach 2:
The risers are nested within the flue block structure, with the first riser and second riser positioned inside the flue block at different elevations. This nesting approach integrates the flow optimization function directly into the flue block without adding external complexity
2Productivity
If risers of different heights are integrated, then gas and air mixing at various elevations is improved, but manufacturing complexity increases
Solution Approach 1:
Multiple risers of different heights are merged into a single integrated flue block structure. The first riser extends to a first elevation and the second riser extends to a second elevation, both within the same flue block, enabling simultaneous multi-level mixing without requiring separate components
Solution Approach 2:
The risers are designed with different height parameters (first riser height vs. second riser height) to optimize mixing at different elevations. This parameter variation allows tailored flow control for gas and air mixing while maintaining a unified flue block design
3Productivity
If integrated risers are added to flue block, then combustion efficiency is improved, but heat loss is reduced
Solution Approach 1:
The risers are positioned and configured in advance within the flue block to pre-optimize the mixing of gas and air before combustion occurs. The first riser and second riser are strategically placed at different elevations to ensure proper fluid flow rates and mixing characteristics are established prior to the combustion process
Solution Approach 2:
The optimized flow paths created by the risers enable gas and air to rapidly mix and move through the flue block, reducing the time for which heat is exposed to potential loss conditions. This accelerated flow through the integrated riser system minimizes heat loss while maintaining high combustion efficiency

AI summary
A flue block for a heating wall of a coke oven battery, the flue block having a proximal end and a distal end, the flue block comprising a first aperture disposed within the flue block, and a riser arranged in said first aperture. The flue block may also comprise a second aperture disposed therein, the second aperture spaced apart from the first aperture, and a second riser arranged in the second aperture. The flue block may be configured such that the riser is arranged to extend past the proximal end of the flue block. The flue block may be also configured such that the first riser extends past the proximal end. The flue block may be further configured such that the second riser extends past the proximal end.
