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.
