Abstract: A water heater includes a water tank having an inlet and an outlet, and a flue extending through the tank. A nozzle is positioned near a first end of the flue, arranged so as to emit a fuel stream into the flue, and a flame holder is located within the flue in a position to receive the fuel stream and to hold a flame entirely within the flue. A controller variably controls a flow of fuel to the nozzle according to a temperature of water in the tank.

Abstract: According to embodiments, a co-fired or multiple fuel combustion system is configured to apply an electric field to a combustion region corresponding to a second fuel that normally suffers from poor combustion and/or high sooting. Application of an AC voltage to the combustion region was found to increase the extent of combustion and significantly reduce soot evolved from the second fuel.

Abstract: A combustion system outputs fuel gas from a plurality of fuel ejectors toward a forward end of a burner wall and preheats a perforated flame holder by sustaining combustion reaction of the fuel gas at combustion zone between the burner wall and a perforated flame holder. The combustion system then outputs fuel gas from the fuel ejectors onto the perforated flame holder and sustains a combustion reaction of the fuel gas within the perforated flame holder.

Abstract: Technologies are provided for employing an ion flow to control a combustion reaction. A combustion reaction is supported at a burner or fuel source. One or more electrical signals are applied to an ionizer to generate an ion flow having a first polarity. The ion flow is introduced to the combustion reaction or a reactant at a first location, imparting a corresponding charge to the combustion reaction. The first location is at least intermittently upstream with respect to a reaction front of the combustion reaction. One or more of the electrical signals are applied to a first electrode at a second location downstream of the first location, which provokes a response by the combustion reaction according to the applied charge. The combustion reaction is controlled by selection of the one or more electrical signals.

Abstract: An ionizer provides charged particles to charge a combustion reaction. A conductive flame holder cooperates with the charged combustion reaction to hold the combustion reaction away from a fuel nozzle. Dilution and/or premixing of the fuel in the region between the fuel nozzle and the conductive flame holder results in a reduced flame temperature. The reduced flame temperature results in a reduced output of oxides of nitrogen (NOx).
