Claim:
1. An electrically stabilized burner, comprising: a fuel nozzle configured to provide a fuel jet flowing a fuel through a surrounding volume and entraining a first quantity of oxidant, air, or flue gas, wherein the fuel and the first quantity of oxidant, air, or flue gas are configured to be ignited to provide a combustion reaction; a conductive flame holder configured for mounting proximate the fuel jet; a charger disposed to cooperate with the conductive flame holder to cause a combustion reaction to be stabilized adjacent to the flame holder; and a mixer configured to mix the fuel and the first quantity of oxidant, air or flue gas above the conductive flame holder; wherein the conductive flame holder, the mixer, and the charger are configured as an integrated unit; and wherein the mixer further comprises: a first electrical insulator disposed between the charger and the conductive flame holder; a first power supply operatively coupled to the charger and operatively coupled to the conductive flame holder; and one or more fluid passages each configured to project a fluid jet tangentially into the combustion reaction, the one or more fluid passages being arranged to drive the combustion reaction in a stream-wise vortex.
