Shenhai tawg-pov thawj
Cov “abc ua” sawv cev rau kev faib cov pa roj, categorized rau hauv peb theem - IIA, IIB, thiab IIC-raws li qhov kev sim siab tshaj plaws kev nyab xeeb qhov sib txawv (MESG) los yog qhov tsawg kawg nkaus igniting tam sim no (MIC).
| Hom mob | Gas Classification | Cov pa hluav taws xob | Yam tsawg kawg nkaus Ignition Spark Zog |
|---|---|---|---|
| Sub Kuv | Kuv | Methane | 0.280mJ |
| Factories sab nraum lub Mine | IIA | Propane | 0.180mJ |
| IIB | Ethylene | 0.060mJ | |
| IIC | Hydrogen | 0.019mJ |
Ntawm no, IIC kev faib tawm yog suav tias yog qhov txaus ntshai tshaj plaws, nrog IIB thiab IIA tom qab hauv kev txo qis ntawm kev pheej hmoo. Gases poob raws li IIC kev faib tawm suav nrog hydrogen, acetylene, carbon disulfide, ethyl nitrate, thiab dej gas. Cov nyob rau hauv qeb IIB encompass ethylene, coke cub gas, propyn, thiab hydrogen sulfide. Kev faib tawm IIA suav nrog cov pa roj xws li methane, ethane, tshuaj benzene, thiab diesel.
