Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current chemical chimney sweeping methods face inefficiencies due to rapid release of active ingredients from powders and high binder content in solid compositions, leading to incomplete combustion and reduced effectiveness in soot and tar deposit removal.
Innovation Solution
A solid combustible composition with a matrix of combustible particles, powders, and granules containing metal and ammonium salts, where the granules have a high concentration of chemical active ingredients for controlled vapor release, optimizing the distribution and intensity of active agents for enhanced efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If chimney sweeping powder is used, then the active ingredients are quickly released in vapor form, but the action is too rapid and does not provide good results compared to prolonged action
Solution Approach 1:
The chemical active ingredients are segmented into two distinct forms: powder (5-20% of composition) for rapid initial release and granules (20-40% of composition) for prolonged sustained release. This segmentation allows the composition to provide both quick action and prolonged effectiveness, resolving the contradiction between release speed and elimination effectiveness.
Solution Approach 2:
The invention changes the physical state parameters of the active ingredients by using both powder and granule forms with different size distributions. The powder form (fine particles) vaporizes quickly while the granule form (coarser particles) provides sustained release over time, allowing the system to operate effectively at different temporal scales.
2Strength
If a large quantity of binder is used to obtain sufficient cohesion, then the composition has adequate structural integrity, but the combustion speed increases and efficiency is reduced
Solution Approach 1:
The invention optimizes the binder quantity parameter to a specific range (5-15% by weight) that provides sufficient cohesion for structural integrity while maintaining optimal combustion efficiency. This precise parameter control resolves the contradiction between strength and productivity by finding the optimal balance point.
3Reliability
If a large quantity of chemical active ingredient is used to improve soot elimination, then the effectiveness increases, but the quantity of substance required increases
Solution Approach 1:
The active ingredients are segmented into powder and granule forms that release at different rates. The powder component provides rapid initial action while the granule component ensures prolonged sustained release, maximizing the utilization efficiency of the active ingredients and reducing the total quantity needed compared to using a single form.
Solution Approach 2:
The invention creates a composite material system combining powder and granule forms of active ingredients with combustible support and binder. This composite structure allows synergistic interaction between components, improving the overall effectiveness per unit of active ingredient and reducing the total quantity required.
4Duration of action of moving object
If high pressure compression is used to delay combustion, then the release of active ingredients is slow and continuous, but satisfactory soot elimination is not achieved due to small quantity of active agents
Solution Approach 1:
The invention segments the active ingredients into powder and granule forms with different combustion characteristics. The powder form burns quickly providing rapid initial release, while the granule form burns slower providing prolonged sustained release. This segmentation ensures both adequate duration and sufficient total quantity of active ingredient release for effective soot elimination.
