The process plants need a device which can detect flame in the burners to monitor the continuous flame in order to prevent catastrophic fires. To select such equipment, one should need to be careful. Search for the modern technology product and market, before purchasing the product to get the best. There are the various types of the flame sensors among which UV flame sensor is one of the most influential products which is preferred due to its fascinating features. It can detect the flame in the burner from 0 to 50 feet away. It is a thin, rod structured, metal rod which is fixed in the burner in front of the flame stream.
The working principle of the device is to detect the flame efficiently and give the signal to the system which alarms the operator. Whenever the valve is open it, the flame is present and sensors have to detect it at the accurate time. Sometimes the system becomes slow and delays the detection due to the downtime. The dirt gets deposited in the opening of the sensor due to the presence of carbon which reduces the working efficiency of the device. Some people get confused and think the system has broken down. While it is not broken, but the dirt enters its way and it has less tolerance for variations. The slightest coating of the carbon causes the misread and shut it down.
To Keep It Working Again, You Can Follow These Points:-
Shut Down The Power: You should shut down the power before checking the sensor. This ensures the safety of entire setup and turning the thermostat (temperature control) off is important. If this option is not available, you can shut down the entire setup.
Remove The Flame Sensor: The sensor is easily accessible and can be unbolted with a screwdriver. After removing the screws, take it off and you can clean it better. Carefully remove it and detach the wire.
Clean The Device: After you take it off, clean it with sandpaper. Rub it gently using the to and fro motion and don’t go over it. Wipe the left over with a clean and dry paper towel. Don’t use wet cloth over it.
Check The Results: After you clean the device, fix it back and check if the results. If it starts up within a few seconds or fan immediately kicks on, it is normal. Try to carry out a process successfully.
