Abstract:
In a combustion system, a charge source is configured to cooperate with a collection plate and a director conduit to cause at least one particle charge-to-mass classification to be reintroduced to a flame for further reaction.
Abstract:
A combustion system such as a furnace or boiler includes a perforated reaction holder configured to hold a combustion reaction that produces very low oxides of nitrogen (NOx).
Abstract:
A combustion system includes a perforated reaction holder having perforations defined to compensate for a non-uniform velocity of fuel and/or oxidant received across an input face of the perforated reaction holder.
Abstract:
A combustor may include a nonmetallic combustor body configured to hold a combustion reaction. The combustor may include and one or more electrodes disposed outside the nonmetallic combustor body and configured to apply electrical energy to the combustion reaction. The combustor may include a power supply operatively coupled to the one or more electrodes.
Abstract:
A combustion system includes a subsystem for electrically biasing or charging a flame and a virtual electrode launcher configured to launch a virtual electrode in proximity to the flame or combustion gas produced by the flame.
Abstract:
Technologies are presented for selecting an electrode gain value for applying electricity to control a combustion reaction. For example, a system can include one or more electrodes, an electrode gain selector configured to select an operative electrode gain value for the one or more electrodes, and a power supply operatively coupled to the one or more electrodes. The power supply can be configured to apply the electricity to the combustion reaction via the one or more electrodes at the operative electrode gain value.
Abstract:
A burner includes a flame positioning mechanism. The flame positioning mechanism includes a flame charger, a plurality of electrodes placed a respective distances along a fuel stream propagation path, and an electrode switch configured to place a subset of the plurality of electrodes into electrical continuity with a holding voltage. Current flow between the flame charge and the holding voltage anchors the flame to an electrode placed into electrical continuity with the holding voltage.
Abstract:
A burner includes a porous flame holder configured to support a combustion reaction to achieve a very low output of oxides of nitrogen (NOx).
Abstract:
A fire tube boiler includes a perforated flame holder configured to hold a combustion reaction that produces very low oxides of nitrogen (NOx).
