English Abstract

The difficult challenges facing the designers and engineers of combustion systems are the flame stability (flame stability map) represented by the limits of flashback and blow-off.

In this study, acetylene gas was combined with Iraqi liquefied petroleum gas at rates (10% - 50% ).

The reason for choosing these two components is the low cost and ease of access to it.

Where the flashback limits (critical velocity gradient) were obtained from (40-485) 1/sec, while the blow-off limits were (265-2510) 1/sec with a diameter of 25 cm for the burning nozzle diameter only for Iraqi LPG without mixing acetylene.

While in the case of mixing 10% acetylene, the flashback limits (critical velocity gradient) were from (30-520) 1/sec and the blow-off limits (440-3985) 1/sec for the same diameter of the muzzle of 25 cm.

Whereas, when mixing 30% of the acetylene, the flashback limits (critical velocity gradient) were from (55-575) 1/sec and the blow-off limits (570 - 4050) 1/sec.

From the above three cases, noticed a relative expansion of the flame stability map for the flashback boundaries, while at the blow-off limits the amplitude was clear and large, which indicates the confidence in mixing acetylene with Iraqi LPG and obtaining a larger flame stability map.

Thus, it stimulates its use in industrial fields and gas turbine power stations.
