Abstract: An apparatus for enhancing flame radiation includes a flame charging system and an electrically isolated electrode. A time-varying voltage is applied to the flame charging system and the flame charging system imparts a corresponding time-varying charge or time-varying voltage onto the flame. The flame responds to the time-varying charge or voltage by increasing its luminosity.

Abstract: A burner supporting primary and secondary combustion reactions may include a primary combustion reaction actuator configured to select a location of the secondary combustion reaction. A burner may include a lifted flame holder structure configured to support a secondary combustion reaction above a partial premixing region. The secondary flame support location may be selected as a function of a turndown parameter. Selection logic may be of arbitrary complexity.

Abstract: A solid fuel burner may include a system for electrodynamic homogenization. One or more electrodes may apply an electric field to burning solid fuel or a region proximate the burning solid fuel. The electric field causes mixing and homogenization of volatilized fractions of the solid fuel, combustion gases, and air. The improved mixing and homogenization may reduce emission of carbon monoxide (CO), reduce emission of oxides of nitrogen (NOx), reduce oxygen in flue gas, increase temperature of flue gas, and/or allow for a larger grate surface.
Abstract translation: 固体燃料燃烧器可以包括用于电动均匀化的系统。 一个或多个电极可以施加电场来燃烧固体燃料或靠近燃烧的固体燃料的区域。 电场引起固体燃料，燃烧气体和空气的挥发分数的混合和均化。 改进的混合和均化可以减少一氧化碳（CO）的排放，减少氮氧化物（NOx）的排放，减少烟道气中的氧气，增加烟气的温度和/或允许更大的炉排表面。

Abstract: A perforated flame holder and burner including a perforated flame holder provides reduced oxides of nitrogen (NOx) during operation. The perforated flame holder includes a pattern of elongated apertures extending between a proximal and a distal surface of the flame holder relative to a fuel nozzle. The perforated flame holder can provide a significantly reduced flame height while maintaining heat output from the burner.
