Flue Gas Passage Footing Segmentation for Insulation Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing manufacturing method for flue gas passage sections results in undefined leaking of hardening insulation mass, leading to transportation damage and difficulties in mounting, which can cause flue gas leakages due to hardened insulation mass hindering the discharge channel and undefined filling levels.
Innovation Solution
A method involving a footing with an inner and outer wall and a bottom wall, forming a placement channel that allows the inner and outer jackets to be positioned with a difference in height, directing any escaping insulation mass outside, ensuring the inner jacket remains free from hardened insulation, and using a synthetic material footing for easy removal after hardening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a footing is used to keep the inner and outer jackets mutually positioned during manufacturing, then the jackets are properly aligned, but insulation mass leaks away along the footing and hardens against the jackets, causing mounting difficulties and undefined filling levels
Solution Approach 1:
The footing is divided into two distinct levels: a first level with a first height that supports the inner jacket, and a second level with a second height that supports the outer jacket. The inner jacket is positioned higher than the outer jacket, creating a height difference that prevents insulation mass from leaking along the footing and hardening against the jackets, thereby eliminating mounting difficulties while maintaining positioning accuracy.
2Reliability
If insulation mass is cast to fill the intermediate space, then heat insulation is provided, but the filling level becomes undefined due to leaking insulation mass
Solution Approach 1:
The footing structure is segmented into two height levels, creating distinct support surfaces for the inner and outer jackets. This segmentation establishes a defined geometric boundary for the intermediate space, ensuring that the insulation mass fills a precisely defined volume with a clear upper surface, thereby providing both reliable heat insulation and a well-defined filling level for subsequent mounting operations.
3Object-affected harmful factors
If the flue gas passage section is carefully wrapped in wrapping materials to prevent damage, then transportation protection is improved, but transportation damage still occurs such as dents along the edges
Solution Approach 1:
The discharge channel is pre-assembled and positioned within the flue gas passage section before the insulation mass is cast and hardened. This preliminary action ensures that the discharge channel is securely in place before any potential damage occurs during transportation, maintaining the integrity of the flue gas passage even when wrapping materials are compromised or dents occur along the edges.

Function Achieved in This Case
This method prevents the leakage and hardening of insulation mass within the flue gas passage section, reducing transportation damage and facilitating easier assembly by maintaining a clear inner jacket and ensuring a defined filling level, thus minimizing flue gas leakages.

AI summary
Assembly of a flue gas passage section, a separate coupling strap for in the extension of the flue gas passage section coupling an equal or identical flue gas passage section, and a separate coupling strap carrier with which the flue gas passage section carries the coupling strap, wherein the flue gas passage section is provided with a circumferential metal inner jacket, a circumferential metal outer jacket and a circumferential intermediate space between the inner jacket and the outer jacket, wherein the intermediate space over the axial longitudinal direction of the flue gas passage section is filled with an insulating material up to a height at which the insulating material is recessed from a first outer end of the flue gas passage section in order to form a circumferential accommodation space between the inner jacket and the outer jacket which space is accessible in axial direction, for fitting or slightly clamping accommodation of an opposite second outer end of the flue gas passage section to be coupled thereto, wherein the coupling strap carrier at least partially covers the first outer end and the coupling strap extends in a circumferential manner around the part of the outer jacket bounding the accommodation space.
