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.
Claims36
A combustion system, comprising:
- a fuel and oxidant source configured to output fuel and oxidant;
- and
- a flame holder including:
- a plurality of slats arranged such that a cross-sectional centerline of each slat is parallel with the cross-sectional centerline of each other slat, each slat having:
- a first edge proximal to the fuel and oxidant source;
- and
- a second edge distal from the fuel and oxidant source;
- a support structure including a plurality of at least first slots, each first slot formed to receive at least a first end face of a respective slat;
- and
- a plurality of combustion channels each between respective adjacent slats, each combustion channel having a width corresponding to a distance between the respective adjacent slats and a length corresponding to a distance between the first edge and the second edge of one of the respective adjacent slats, the length being at least five times the width, the flame holder being positioned to receive the fuel and oxidant into the combustion channels and to collectively hold a combustion reaction of the fuel and oxidant primarily within the combustion channels.
