The torch issue
Thread Content
Our company is an oil refining enterprise, and the flare tower (overhead flare) at our facility often goes out recently. Please help analyze the reasons for this. Also, could everyone explain the differences between overhead flares and ground flares, and under what circumstances are overhead flares used? Under what circumstances are ground torches used?
Regarding the flare: In winter, it usually goes out due to low temperatures and the liquefaction of gas! Whether a torch uses an elevated setup depends mainly on whether there is liquid in the medium being discharged, and on the amount of liquid present! Including when in an accident state ； If the medium being discharged is not a liquid, a low-profile option can be chosen! This is just my personal opinion! If the building is mainly used for a torch system, it’s better to check the relevant standards
Adding to what was said on the 2nd floor: the permanently lit torch burner might be clogged； The back pressure of the long-burning burner is low, making it prone to being blown out at high altitudes ； Some plants use a single permanent-burn burner in order to save fuel gas, which can also lead to flameout.
Types and composition of surface flares: As facilities for the safe and efficient discharge of gases or liquids in refineries or petrochemical plants, the proper operation of flare systems is crucial for preventing disasters resulting from plant shutdowns in case of emergencies such as fires or power outages. Torches come in different types based on various classification methods. Based on whether the burner is above or below ground level, they can be divided into ground torches and elevated torches. According to the design of the burner, they can be classified as single-point combustion torches or multi-burner torches
Has nitrogen mixed into the system? A large amount of it can also cause the engine to stall.
It’s possible that the pipeline or filter is blocked, which has caused a decrease in the flow rate of fuel gas entering the pilot burner
The reasons are as follows: 1. The calorific value of the exhaust gas is too low. 2. The flow rate of the exhaust gas is too low, which may cause smoldering inside. 3. There is a problem with the ignition system.
