According to an embodiment, a combustion system is provided, which includes a nozzle configured to emit a diverging fuel flow, a flame holder positioned in the path of the fuel flow and that includes a plurality of apertures extending therethrough, and a preheat mechanism configured to heat the flam

대표청구항 ▼

1. A burner, comprising: a primary nozzle having a longitudinal axis and configured to emit a fuel flow;a primary flame holder having first and second faces and a plurality of apertures extending through the flame holder from the first face to the second face, positioned with the first face toward the nozzle and intersecting the longitudinal axis of the nozzle; anda preheat mechanism configured to preheat the primary flame holder, the preheat mechanism including: a preheat nozzle;a secondary flame holder configured to support a flame at a position between the primary nozzle and the first face of the primary flame holder and to introduce turbulence into the fuel flow emitted by the primary nozzle; anda mechanism configured to move the secondary flame holder between an operative and an inoperative position. 2. The burner of claim 1, wherein the secondary flame holder is movable between the operative position, in which the secondary flame holder introduces turbulence into the fuel flow, and the inoperative position, in which the secondary flame holder is spaced away from a path of the fuel flow. 3. The burner of claim 1, comprising a controller configured to switch the burner from a preheat condition to an operative condition. 4. The burner of claim 3, wherein the controller is configured to hold the burner in the preheat condition for a first time period, and to switch the burner from the preheat condition to the operative condition at the end of the first time period. 5. The burner of claim 3, wherein the controller is configured to receive a signal indicative of a temperature of the primary flame holder, and to switch the burner from the preheat condition to the operative condition while the temperature of the primary flame holder is above a temperature threshold. 6. The burner of claim 3, wherein the controller is configured to regulate an operating level of the burner. 7. A method, comprising: performing a burner startup procedure, including applying thermal energy to a primary flame holder by supporting a preheat flame at a position between a primary nozzle and the primary flame holder with a preheat nozzle and a secondary flame holder, the secondary flame holder being positioned between the primary nozzle and the primary flame holder;terminating the burner startup procedure after a temperature of a portion of the primary flame holder is above a startup temperature threshold;emitting a flow of fuel from the primary nozzle at an operational rate;introducing turbulence into the flow of fuel with the secondary flame holder;supporting a flame within a plurality of apertures extending through the primary flame holder; andmoving the secondary flame holder between an operative position and an inoperative position with a mechanism. 8. The method of claim 7 wherein the terminating the burner startup procedure includes reducing a concentration of oxygen in a flow of oxidizer fluid.
