Abstract: A combustion system supports a swirl-stabilized preheating flame with a preheating fuel and an oxidant. The combustion system preheats a perforated flame holder with the preheating flame. After the perforated flame holder has been preheated to the threshold temperature, the combustion system outputs a primary fuel. The perforated flame holder receives a mixture of the primary fuel and the oxidant supports a combustion reaction of the primary fuel and the oxidant.

Abstract: A combustion system includes a fuel and oxidant source and a flame holder. The flame holder includes a plurality of discrete slats arranged in parallel defining combustion channels between adjacent slats. The fuel and oxidant source outputs fuel and oxidant into the combustion channels. The flame holder holds a combustion reaction of the fuel and oxidant in the combustion channels.

Abstract: A combustion system includes a fuel and oxidant source that outputs fuel and oxidant, a first perforated flame holder, and a second perforated flame holder separated from the first perforated flame holder by a gap. The first and second perforated flame holders sustain a combustion reaction of the fuel and oxidant within the first and second perforated flame holders.

Abstract: Technologies are provided for employing an ion flow to control a combustion reaction. A combustion reaction is supported at a burner or fuel source. One or more electrical signals are applied to an ionizer to generate an ion flow having a first polarity. The ion flow is introduced to the combustion reaction or a reactant at a first location, imparting a corresponding charge to the combustion reaction. The first location is at least intermittently upstream with respect to a reaction front of the combustion reaction. One or more of the electrical signals are applied to a first electrode at a second location downstream of the first location, which provokes a response by the combustion reaction according to the applied charge. The combustion reaction is controlled by selection of the one or more electrical signals.
