Abstract
A method for a combustion system includes outputting fuel from an adjustable-position fuel nozzle onto a perforated flame holder, the fuel being directed for mixture with an oxidant en route to the perforated flame holder. A combustion reaction of the fuel and the oxidant is supported within the perforated flame holder. A position of the adjustable-position fuel nozzle may be changed relative to the flame holder. A first flow of fuel may be output when the adjustable position fuel nozzle is in an extended state, and a second flow of fuel may be output when the adjustable-position fuel nozzle is in a retracted state.
