A gas-powered oven includes a cooking surface and a heat deflecting frame, such that the cooking surface and heat deflecting frame collectively define at least a portion of a cooking chamber. An outer housing extends around the cooking surface and the heat deflecting frame, with the outer housing having an opening formed therein and in communication with the cooking chamber. A first burner is connectable to a gas source and is located within the outer housing and spaced from the cooking chamber. The first burner is elongate and includes a first array of openings formed therein. A second burner is connectable to the gas source and extends into the cooking chamber toward a portion of the heat deflecting frame. The second burner includes a tapered passageway and an expanding passageway downstream of the tapered passageway to achieve desired flow characteristics of the gas flowing through the second burner.

Burner holders and cartridges of a furnace are described herein, which include a support assembly and a manifold. The support assembly is configured to support one or more burners. For example, the support assembly may include a burner holder with a cutout region, which may allow a burner to be moved between an operational position and a disengaging position by twisting the burner. The cutout region can allow the one or more burners to be removed or installed relatively easily, without the need of removing the manifold from the support assembly. The manifold can be attached to the support assembly by, for example, using one or more orifices as fasteners.

The present disclosure discloses a combustor assembly and a gas water heater, the combustor assembly includes a burner and a combustor accommodating the burner, the combustor defines an opening facing upwards, the combustor further includes a front support and a rear support, and the front support and the rear support cooperatively clamp the front side and the rear side of the burner; the front support includes a first base plate extending up and down and a first limit plate connecting to an upper end of the first base plate and extending backwards, and the rear support includes a second base plate extending up and down and a second limit plate connecting to an upper end of the second base plate and extending forwards; and the first limit plate defines a first cooling hole, and/or, the second limit plate defines a second cooling hole.

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.
