Burner Cooling Pipe Breakage Detection via Light Sensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing burner devices in gasification furnaces face a significant challenge due to the wear and tear of cooling pipes caused by high temperatures and radiation, leading to refrigerant leakage and necessitating frequent shutdowns, which decreases the operation rate and can result in damage to the burner body.
Innovation Solution
A burner device equipped with a light detection unit, including optical fibers, to monitor internal light within the cooling pipes, allowing for early detection of breakages and enabling controlled refrigerant supply to prevent immediate shutdown, thus extending maintenance time and reducing operational disruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the cooling pipe is disposed on the furnace protruding portion to cool the burner body, then the burner body is protected from heat load, but the cooling pipe is gradually worn by radiation and thermal current, leading to refrigerant leakage
Solution Approach 1:
The light detection unit continuously monitors the cooling pipe for early signs of wear and breakage before refrigerant leakage occurs. By detecting changes in light transmission through the cooling pipe wall, the system can identify degradation at an early stage and alert operators to replace the cooling pipe before it fails, preventing refrigerant leakage and burner body damage.
Solution Approach 2:
The light detection unit provides real-time feedback on the condition of the cooling pipe by measuring light transmission properties. This feedback mechanism allows continuous monitoring of cooling pipe integrity, enabling predictive maintenance and preventing catastrophic failure from gradual wear caused by radiation and thermal current exposure.
2Loss of time
If the refrigerant flow amount is reduced to delay shutdown, then maintenance time is extended, but the burner body may be damaged due to insufficient cooling
Solution Approach 1:
The light detection unit detects cooling pipe degradation before it leads to complete failure or refrigerant leakage. This early detection allows operators to plan and execute maintenance during scheduled shutdowns rather than experiencing unplanned emergency shutdowns, ensuring the burner body is properly cooled and maintained without compromising furnace operation time.
3Temperature
If the cooling pipe is surrounded by the furnace protruding portion to protect from heat load, then cooling effectiveness is improved, but detection of breakage becomes difficult
Solution Approach 1:
The light detection unit acts as an intermediary sensing mechanism that can detect cooling pipe condition without requiring direct physical access to the pipe. By measuring light transmission through the cooling pipe wall from the exterior, the system can detect breakages and degradation while the cooling pipe remains in its protective position around the furnace protruding portion, maintaining both cooling effectiveness and detection capability.
