Abstract
A combustion system includes a perforated flame holder, an oxidant source, and an adjustable fuel nozzle. The oxidant source outputs oxidant. The adjustable fuel nozzle outputs fuel onto the perforated flame holder. The perforated flame holder supports a combustion reaction of the fuel and oxidant within the perforated flame holder. The position of the adjustable nozzle relative to the perforated flame holder can be adjusted to achieve selected characteristics of the combustion reaction within the perforated flame holder.
Claims33
A combustion system, comprising:
- an oxidant source configured to output oxidant into a combustion volume;
- an adjustable-position fuel nozzle configured to output fuel into the combustion volume;
- and
- a perforated flame holder disposed in the combustion volume and oriented to receive the fuel from the adjustable-position fuel nozzle and to support a combustion reaction of the fuel and the oxidant within the perforated flame holder, the adjustable-position fuel nozzle being configured to extend toward and retract from the perforated flame holder.
