Results of experiments on ignition of propane-air mixture flow with a help of deeply subcritical MW discharge are described. The discharge was initiated by a linear electromagnetic vibrator, which axis was parallel to a vector of a flow velocity. The discharge realized by a field of linearly polarized electromagnetic beam was burning in a stern area of the initiator. The flammable mixture flow was formed in a working chamber in a form of a submerged stream, and it had a velocity about tens of meters per second. Integral photo detection of the discharge appearance and combustion area of the mixture was made in experiments. Gas temperature in the discharge trail and in flammable mixture area has been measured. Experiments have shown that MW discharge ignites propane-air mixture and spatially stabilizes combustion area. Ignition of rich and essentially lean mixtures has been realized. Dependence of gas temperature drop on decrease of propane content in the mixture in the trail of the combustion area has been determined. Influence of propane share in the mixture on geometric parameters of the combustion area has been investigated. |
