Claim Text:
1. A method for supporting an oscillating combustion reaction, comprising: outputting a fuel jet having a continuous rate and an expanding area; supporting a combustion reaction with the fuel jet; providing a first flame holder disposed distally along the fuel jet, the first flame holder including a refractory flame holder disposed adjacent to the fuel jet; providing a second flame holder disposed proximally along the fuel jet, the second flame holder including a conductive metal flame holder disposed adjacent to the fuel jet; maintaining electrical continuity between the second flame holder and an activation voltage; and modulating a charge applied to the fuel jet or the combustion reaction; wherein modulating a charge applied to the fuel jet or the combustion reaction includes periodically applying the charge to the fuel jet or the combustion reaction to cause the combustion reaction to be held by the second flame holder and periodically discontinuing the charge to the fuel jet or the combustion reaction to cause the combustion reaction to be held by the first flame holder.
