Minimum ignition energy of combustible gases in air
Thread Content
I’m seeking help from experts – does anyone have a table showing the minimum ignition energy of combustible gases in air, along with the sources of relevant standards or regulations? Thank you very much!
GB 26164.1-2010 Safety Regulations for Electric Power Industry – Part 1: Thermal and Mechanical Aspects; GB 50058-2014 Design Code for Electrical Installations in Explosive Environments; GB/T 10686-2013 Test Methods for Explosion Protection of Copper Alloy Tools; GB 50493-2009 Design Code for Detection and Alarm Systems of Flammable and Toxic Gases in Petrochemical Industries; GB 3836.1-2010 Explosive Environments – Part 1: General Requirements for Equipment; GB/T 14288-1993 Method for Determining the Minimum Static Ignition Energy of Flammable Gases and Volatile Liquids; Safety Manual for Common Chemical Hazards; Practical Techniques in Fire Safety. I have reviewed all these standards and regulations, and it is only in the book on practical fire safety techniques that relevant data can be found, but it seems that the information there is not accurate
Substance name Minimum ignition energy (mJ) Substance name Minimum ignition energy (mJ) Ethane 0.285 Butane 0.68 Propane 0.305 Propyne 1.15 Methane 0.47 Ethyl acetate 1.42 Heptane 0.70 Dimethyl ether 0.33 Acetylene 0.02 Diethyl ether 0.49 Ethylene 0.096 Isopropyl ether 1.14 Propyne 0.152 Triethylamine 0.75 Propylene 0.282 Ethylamine 2.4 Butadiene 0.175 Furan 0.225 Chloropropane 1.08 Benzene 0.55 Methanol 0.215 Ethylene oxide 0.087 Isopropanol 0.65 Carbon disulfide 0.015 Acetaldehyde 0.325 Hydrogen 0.02 These are some of the data listed here
