Heat-Resistant Ceramic Burner Collar for Thermal Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-burner heating systems, the highly conductive metallic flanges used to direct hot combustion products towards heat exchangers suffer from heat transfer-induced damage and deformation due to the proximity of the flame, leading to inefficiencies and potential system failure.
Innovation Solution
A heat-resistant collar is designed to couple the burner to a partition plate, featuring a flange that extends outward from its body and is receivable within an embossment in the partition plate, limiting heat transfer and preventing damage by using materials like ceramic or plastic that can withstand high temperatures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If metallic flanges are used to direct hot combustion products, then the flame flow direction is controlled effectively, but heat transfer causes damage and deformation to the partition plate
Solution Approach 1:
The patent introduces a ceramic flange as an intermediary component between the metallic partition plate and the combustion flame. This ceramic flange serves as a heat barrier that directs the flame flow while preventing excessive heat transfer to the partition plate, thereby resolving the contradiction between effective flame direction control and heat transfer damage prevention
Solution Approach 2:
The patent employs a composite structure combining ceramic material for the flange in contact with the flame and metallic material for the partition plate. This composite approach leverages the high heat resistance of ceramic materials while maintaining the structural integrity and conductivity benefits of metallic materials in the partition plate, effectively managing heat transfer while controlling flame direction
2Strength
If highly conductive metallic flanges are used, then structural strength is maintained, but heat conduction causes deformation of the partition plate
Solution Approach 1:
The ceramic flange acts as a thermal intermediary that blocks heat conduction from the combustion flame to the metallic partition plate. This intermediary layer maintains the structural strength needed for flame direction control while preventing the temperature rise that would cause partition plate deformation
Solution Approach 2:
The patent changes the material parameter (thermal conductivity) of the flange from high (metallic) to low (ceramic) to reduce heat transfer. This parameter change allows the flange to maintain its structural function while significantly reducing the temperature transmitted to the partition plate, preventing deformation
