Solution Overview
Problem
The existing power generation systems do not adequately address the connection of combustion exhaust gas passages with ducts, leading to potential gas leakage due to incomplete combustion, which can result in combustible gases being present in the exhaust gas passage.
Innovation Solution
The system merges exhaust gas from a ventilator with combustion exhaust gas before it enters the duct, diluting any combustible gases and enhancing safety by ensuring the exhaust gas passage is connected to the duct only after merging with the ventilator's exhaust gas, thereby preventing gas leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the combustion exhaust gas passage is connected individually to the duct, then the system structure is simple, but combustible gas leakage risk increases due to incomplete combustion
Solution Approach 1:
The patent merges the combustion exhaust gas passage with the ventilator exhaust gas passage before connecting to the duct. This combining of two exhaust streams dilutes combustible gases and eliminates the need for separate individual connections, thus reducing leakage risk while maintaining structural simplicity.
Solution Approach 2:
The ventilator exhaust gas acts as an intermediary substance that mixes with and dilutes the combustion exhaust gas containing combustible components. This intermediary gas flow reduces the concentration of combustible gases in the duct, preventing hazardous leakage scenarios.
2Reliability
If combustion exhaust gas is diluted with ventilator exhaust gas, then safety against gas leakage improves, but the exhaust gas passage configuration becomes more complex
Solution Approach 1:
The patent combines the combustion exhaust gas passage and ventilator exhaust gas passage into a single merged passage that connects to the duct. This merging approach improves safety through gas dilution while avoiding the need for multiple separate connection points, thus not significantly increasing overall system complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration provides higher safety during potential leakage scenarios compared to systems where exhaust gas passages are connected individually to the duct, as the combustible gases are diluted, reducing the risk of accidents.
Implementation Method 1
the combustible gas can be diluted by merging the exhaust gas from the ventilator with the combustion exhaust gas passage before it flows into the duct

AI summary
A power generation system has a power generation unit (1), a casing (2) accommodating the power generation unit (1), a ventilator (3) configured to ventilate the interior of the casing (2), and a first exhaust gas passage (4) configured to pass therethrough an exhaust gas from the ventilator (3) which is discharged out of the casing (2). The first exhaust gas passage (4) merges with a second exhaust gas passage (6) connected to a duct (11) open to outside air before the second exhaust gas passage (6) is connected to the duct (11), the second exhaust gas passage (6) being configured to pass a combustion exhaust gas from a combustion device (5) configured to generate heat to be supplied to a heat load.
