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 burner includes a flame position actuator configured to control a location at which a flame is held. Combustion supported at a first location corresponds to high fuel dilution. An electric charge is applied to the fuel stream. If electrical power is lost or removed, the flame is shifted to a location corresponding to a lower fuel dilution.

Abstract translation: 燃烧器包括构造成控制火焰保持的位置的火焰位置致动器。 在第一位置支持的燃烧对应于高燃料稀释。 对燃料流施加电荷。 如果电力丢失或消除，则火焰转移到对应于较低燃料稀释度的位置。
