摘要： Various embodiments of a vortex hybrid motor are described herein. In some embodiments, the vortex hybrid motor may include a combustion zone defined by a fuel core and/or motor housing. The combustion zone may include an upper zone and a central zone that each contribute to thrust created by the vortex hybrid motor. In some embodiments, an injection port configuration is described that includes a proximal injection port that may be controlled for modulating a delivery of an amount of oxidizer for adjusting an oxidizer-to-fuel ratio. In some embodiments, a fuel core configuration is described that provides radially varying gradients of fuel in order to achieve desired thrust profiles. In some embodiments, the fuel core may include a support structure and/or a proximal end of a nozzle of the vortex hybrid motor may extend into the fuel core.

摘要： A cylindrical burner apparatus and method which produce low noise levels and are not dependent upon a blower, or natural draft, for providing combustion air flow. A flow of combustion air is induced into a rearward end of a burner tube and a swirling flame is produced in the tube by discharging a gas fuel from a plurality of discharge ports located in the tube.

摘要： A radiant tube burner, wherein an opening cross section of the tube is virtually divided into four areas with two straight lines as boundaries, the two straight lines being obtained by tilting a minor axis of the oval, which is a shape of the opening cross section, by ±45° with a center of the oval as a center, and a flow rate of primary combustion air injected from primary combustion air nozzles located in the areas containing the minor axis of the oval of the virtually divided four areas is lower than a flow rate of the primary combustion air injected from the primary combustion air nozzles located in the areas not containing the minor axis of the oval the four areas.

摘要： A cylindrical burner apparatus and method which produce low NOx emissions and low noise levels without being dependent upon a blower, or natural draft, for providing air flow. A flow of combustion air is induced into a cylindrical burner lube by discharging a gas fuel from a plurality of discharge ports located inside the rearward end of the tube. At least some of the discharge ports are oriented to direct jets of the gas fuel toward flame stabilization structures positioned downstream of the discharge ports.

摘要： A cylindrical burner apparatus and method which produce low NOx emissions and low noise levels without being dependent upon a blower, or natural draft, for providing air flow or flue gas recirculation. A flow of combustion air is induced into the initial tube pass of the burner by discharging a gas fuel from a plurality of discharge ports located in the initial tube pass. At the same time, a flow of recycled flue gas is induced through a bypass duct between a subsequent tube pass of the burner and the initial tube pass by discharging one or more jets of gas fuel through the bypass duct.

摘要： A heat exchanger includes a hollow heat exchanger main body that is enclosed in a radiant tube, and a heat conductor that is disposed on outer periphery of the heat exchanger main body. The heat exchanger performs heat exchange between a first gas flowing in between the radiant tube and the heat exchanger main body and a second gas flowing in hollow interior of the heat exchanger main body, and the heat exchanger comprises a turbulence flow generation promoting unit configured to promote generation of a turbulence flow from the first gas flowing in between the radiant tube and the heat exchanger main body, the turbulence flow generation promoting unit being disposed on the outer periphery of the heat exchanger main body without welding.

摘要： A combustion tube assembly of a water heater includes a combustion tube having an open end, a closed end, and an outflow opening located between the open end and the closed end. A cavity of the combustion tube provides a chamber for a combustion of a water heater fuel that produces an exhaust gas that flows down toward the closed end. The combustion tube assembly further includes a diverter structure positioned inside the combustion tube to divert the exhaust gas such that the exhaust gas flows toward the closed end on a first side of the diverter structure and flows from the first side of the diverter structure to the second side of the diverter structure through a flow opening proximal to the closed end. The outflow opening provides an outlet for the exhaust gas that flows to the second side of the diverter structure to exit the combustion tube.

摘要： Embodiments relate generally to mounting components of a furnace. A mounting assembly may include brackets attached to a burner box of the furnace. Each bracket includes an opening configured to receive a gas line, a recess configured to receive a gas supply valve, a pressure transducer aperture configured to receive a pressure transducer, and slots adjacent to the pressure transducer aperture. The slots are configured to secure the pressure transducer to the bracket.
