Monobloc Angle Pipe With Integrated Reduction for Flue Gas Lining
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for lining flue gas conduits require multiple connections, leading to elongation of the gas path, potential seal defects, and increased complexity, especially when altering direction or working in limited spaces, resulting in higher costs and installation complications.
Innovation Solution
A monobloc compact angle pipe with a threaded flange and inserted flange neck interconnected by an intermediate reduction piece, allowing for directional change without additional connections, thus minimizing the number of tubular parts and eliminating seal-related issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple tubular parts are connected in series to achieve direction change and diameter reduction, then the flue gas conduit can be installed in limited spaces with proper directionality, but the gas path is elongated and seal reliability deteriorates
Solution Approach 1:
The patent combines multiple separate tubular components (angle pipe, reduction piece, straight sections) into a single integrated monobloc element. This merging eliminates the intermediate connections that caused seal reliability issues while preserving the ability to change direction and reduce diameter within the same component, thus resolving the contradiction between adaptability and reliability.
2Adaptability or versatility
If multiple tubular parts are connected in series, then the flue gas conduit can achieve required direction and diameter changes, but the number of connections increases leading to higher defect probability
Solution Approach 1:
The patent integrates the angle change function and diameter reduction function into a single monobloc component, eliminating the need for multiple separate parts and their associated connections. This reduces device complexity while maintaining the required adaptability for direction and diameter modification.
3Ease of operation
If multiple tubular elements are used, then the flue gas conduit can be installed in limited manoeuvring spaces with proper configuration, but installation time and cost increase
Solution Approach 1:
The monobloc design consolidates multiple functions (angle change, diameter reduction, gas flow direction) into a single installable unit. This eliminates the need for on-site assembly of multiple components, significantly reducing installation time and cost while maintaining the ability to navigate confined spaces and achieve proper configuration.
4Manufacturing precision
If individual reduction pieces are successively connected, then the diameter reduction is achieved, but the lined path of combustion gases is elongated
Solution Approach 1:
The patent integrates the diameter reduction function directly into the angle pipe monobloc element, eliminating the need for separate reduction pieces. This shortens the overall lined path length while maintaining precise diameter reduction from the larger insert diameter to the smaller external diameter through the integrated reduction section.
