NGPGMonitoring solution for flammable and explosive gases in aviation coal oil tank area

1Background Introduction

Aviation kerosene, as a flammable liquidVolatile gasMixing with air can easily form explosive mixtures, posing a risk of leakage during transportation, storage, and use. Once leaked, keroseneqiWhen the concentration in the air reaches the explosive limit (0.6%~3.7% by volume), it may cause explosions or fires when exposed to open flames, static electricity, or high temperatures. Therefore, implementing flammable and explosive gas monitoring in aviation coal oil tank areas is the core link to ensure safety.

IILayout of monitoring points

? Tank top and breathing valve: Monitor the concentration of volatile vapors to prevent excessive accumulation.

? Pipeline connections and valves: Focus on detecting areas prone to leakage such as flanges and welds.

? Pump area and loading/unloading platform: monitor the dynamic sealing points and steam release during operation.

? Tank area perimeter:Key monitoring of gas release around the tank area.
