Solution Overview
Problem
Gas generators in cogeneration systems, particularly Stirling systems, face efficiency reduction due to particle deposition on conduits and exchangers, requiring separate cleaning devices that cool gases, making them unsuitable for high-temperature applications.
Innovation Solution
An integrated particle cleaning system utilizing centrifugal forces to separate particles from combustion gases within the gas generator, ensuring clean gases at maximum temperature and reducing mechanical wear and noise by using a static, compact design with a helical discharge conduit and nozzle configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate cleaning devices are used to remove particles from combustion gases, then particle deposition is prevented, but the gases cool down during cleaning and mechanical wear increases
Solution Approach 1:
The patent combines the particle separation function and gas cleaning function into a single integrated cyclone separator unit. The cyclone is directly connected to the gas generator outlet, allowing particles to be separated from combustion gases at high temperature without requiring separate cooling and cleaning stages. This merger maintains gas temperature while achieving effective particle removal.
Solution Approach 2:
The patent extracts the particle separation function from the gas cleaning system and places it at the outlet of the gas generator. By positioning the cyclone separator immediately at the generator outlet, particles are removed before the gases enter the cooling and cleaning stages, preventing deposition in downstream components while maintaining high temperature throughout the process.
2Reliability
If mechanical cleaning devices with moving coils are used, then particles are removed from conduits, but mechanical wear increases and noise is generated
Solution Approach 1:
The patent replaces mechanical cleaning devices with moving coils with a static cyclone separator system. The cyclone uses centrifugal force generated by the gas flow itself to separate particles, eliminating the need for mechanical moving parts, coils, and associated drive mechanisms. This substitution reduces mechanical wear, noise, and device complexity while maintaining effective particle removal.
3Reliability
If cyclone separation is used to clean combustion gases, then particles are separated, but the system requires additional space and complexity
Solution Approach 1:
The patent merges the cyclone separator with the gas generator outlet structure, creating an integrated unit rather than a separate standalone component. The cyclone is positioned and connected such that it forms part of the overall gas generator assembly, reducing the number of separate components and simplifying the system structure while maintaining effective particle separation.
