摘要
The behavior of pulsed flame (PF) and its potential application as a source for syngas production was investigated. Methane/oxygen mixtures of different compositions with and without nitrogen dilution in the temperature range of 278-673 K were studied. This allowed to study the influence of operating temperature, equivalence ratio and dilution on the PF behavior and syngas production efficiency. The PF exhibits two different modes of flame propagation: one relatively slow (several m/s) observed for CH4/O-2 mixtures diluted by nitrogen and another, very fast, with flame speed of similar to 1300 m/s, observed for the mixtures containing only CH4 and O-2 without nitrogen dilution. The exhaust gases emerging from the PF were analyzed by Gas Chromatography (GC) and Fiber Laser Absorption Spectroscopy (FLICAS) for CO:CO2 ratio. The CO:CO2 ratio observed in the PF exhaust was found to be higher than that observed in continuous flame, suggesting additional advantages for employing PF for syngas production.
