The present disclosure is directed to systems and methods for low-CO.sub.2 emission combustion of liquid fuel with a gas-assisted liquid fuel oxygen reactor. The system comprises an atomizer that sprays fuel and CO.sub.2 into an evaporation zone, where the fuel and CO.sub.2 is heated into a vaporized form. The system comprises a reaction zone that receives the vaporized fuel and CO.sub.2. The system includes an air vessel having an air stream, and a heating vessel adjacent to the air vessel that transfers heat to the air vessel. The system comprises an ion transport membrane in flow communication with the air vessel and reaction zone. The ion transport membrane receives O.sub.2 permeating from the air stream and transfers the O.sub.2 into the reaction zone resulting in combustion of fuel. The combustion produces heat and creates CO.sub.2 exhaust gases that are recirculated in the system limiting emission of CO.sub.2.

A combination burner apparatus includes: a housing including a peripheral wall defining an interior cavity; and side-by-side first and second burner assemblies disposed in the housing in fluid communication with the interior cavity, wherein the first burner assembly is of a first burner type, and the second burner assembly is of a second burner type different from the first burner type.

A multijet burner system includes a plurality of fuel nozzles, each configured to support a respective flame, a plurality of charge electrodes, each positioned and configured to apply a charge potential to a fluid flow corresponding to a respective one of the plurality of fuel nozzles, and a charge controller operatively coupled to each of the plurality of charge electrodes and configured to control a voltage potential applied to each respective charge electrode. By selecting the magnitude and polarity of a charge potential applied to individual ones of the flames of the plurality of burners, the flames can be made to change positions, move to selected positions, and redistribute themselves within a volume.

A cement kiln burner device includes a powdered-solid-fuel flow channel, a first air flow channel placed inside the powdered-solid-fuel flow channel to be adjacent to the powdered-solid-fuel flow channel, having means for swirling an air flow, an outer air flow-channel group placed concentrically in an outermost side outside the powdered-solid-fuel flow channel, having three or more second air flow channels adapted to form means for straightly forwarding an air flow, and a combustible-solid-waste flow channel placed inside the first air flow channel. The second air flow channels are placed proximally to each other in a radial direction within a range where air flows ejected from the respective second air flow channels are merged to form a single air flow, and are configured to control flow rates of the air flow ejected from the respective second air flow channels, independently for each second air flow channel.
