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.

The embodiments of the present application disclose a combustion control system of a gas water heater or wall-hanging boiler, and a control method thereof. The system comprises: a flue gas channel consisted of a combustor, a heat exchanger and a stepless speed regulating fan and a smoke tube, which are connected sequentially; a control unit connected to a signal input end of the stepless speed regulating fan; a wind pressure sensor assembly that detects a pressure signal upstream of an impeller of the stepless speed regulating fan, a signal output end of the wind pressure sensor assembly being connected to the control unit; the control unit comprising a storage for storing a correspondence relationship between the pressure signal upstream of the stepless speed regulating fan and a thermal load of the combustor, and a controller that controls operation of the stepless speed regulating fan according to the correspondence relationship. The present application further regulates the rotational speed of the stepless speed regulating fan by detecting the pressure signal upstream of the impeller of the stepless speed regulating fan, thereby achieving a better wind-resistant performance of the present application.

A method for regulating a wood burner that burns wood pellets. For a batch of pellets the method includes, determining the air flowrate and fuel flowrate parameters according to the levels of combustion of the pellets in a defined pellet-fired burner, creating at least one curve, identifying the optimal air and fuel parameters, recording these optimal parameters, the type of burner, the batch number, possibly extrapolating to other pellet-fired burners, recording these extrapolated optimal parameters, labelling each bag with information relating to these optimal parameters, when using a bag of pellets in a domestic pellet-fired burner, reading the information using reading means, and regulating the domestic burner by acting on regulating means that regulate the supply of air and fuel to the burner.

A burner assembly including a gas inlet fixture for use with a burner tube, the gas inlet fixture including a plurality of tabs to engage a neck of a gas control valve to improve ignition and center the gas flow down the center of the burner tube.

Embodiments of the invention provide a gas burner comprising a first venturi configured to supply fuel in a substantially horizontal direction and a second venturi configured to also supply fuel along a substantially horizontal direction. A burner bottom may be coupled to the first venturi and the second venturi, and the burner bottom may be configured to direct fuel from the first venturi and second venturi into a burner base positioned above the burner bottom. The burner base may provide an inner annular chamber and an outer annular chamber separated by a dividing wall, and the inner annular chamber may be configured to receive and direct fuel from the first venturi assembly circumferentially about the burner base and the outer annular chamber may be configured to receive and direct fuel from the second venturi assembly circumferentially about the burner base. A burner cap may be coupled to the burner base to provide a fluidic seal between the inner annular chamber and outer annular chamber, and may be configured to produce flame bodies having radial and upward components.
