Abstract

Abstract: In order to explore minimum ignition energy variation characteristics of industrial syngas (mainly composed of H₂ and CO) under action of volume fraction and inerting effect. Firstly, methane gas was used to determine sensitive conditions of experimental system of minimum ignition energy. Then, minimum ignition energy of H₂/CO syngas with different ratios, as well as N₂ dilution conditions was measured by using a calibrated experimental device under its sensitive conditions. Finally, minimum ignition energy of gas mixture under N₂ dilution was determined. The result shows that in H₂ and CO syngas without inert gas, when volume fraction of H₂ is lower than 25%, it has a great influence on sensitive volume fraction value of system syngas. In H₂ and CO syngas containing N₂, inerting effect is significant when fuel volume fraction is greater than 40%. When fuel volume fraction of H₂ and CO syngas containing inert gas N₂ is less than 40%, contribution of system's minimum ignition energy value mainly depends on volume fraction of H₂.

Key words: H₂/CO syngas, minimum ignition energy, inerting effect, sensitive volume fraction value, inert gas
