摘要： A fuel atomizer that includes a housing having a fuel inlet and at least one primary orifice positioned at the inlet, wherein the at least one orifice configured to disperse a stream of fuel into a plurality of fuel droplets. The plurality of fuel droplets contact a fuel impingement surface to break up the plurality of fuel droplets into a plurality of smaller secondary droplets and create a thin film of secondary droplets on the impingement surface. At least one pressurized air channel delivers an airflow into contact with the secondary droplets. The secondary droplets pass through a plurality of secondary outlet orifices to exit the housing. A size of the plurality of secondary droplets is reduced when passing out of the plurality of secondary orifices.

摘要： A fuel combustion system comprises a discharge nozzle with concentric fuel and air orifices. A fuel conduit is coupled to each fuel orifice for supplying liquid fuel thereto. An air conduit is coupled to each air orifice for supplying air thereto. The fuel and the pressurized air only mixing with one another, upon being discharged from the respective fuel and air orifices, to form a fuel mixture. A supplemental air source supplies supplement air to facilitate combustion. An air deflector sleeve at least partially surrounds and accommodates the at least one discharge nozzle and a cylindrical blast tube surrounding the air deflector sleeve and an outlet end of the cylindrical blast tube supports a flame retention head. The flame retention head redirects the supplement air radially inward, through openings in the air deflector sleeve and the flame retention head, to assist with combustion of the fuel mixture.

摘要： A burner for an exhaust purifying device includes a tube, an air supply port for supplying air for combustion into the tube, a fuel supply port for supplying fuel into the tube, and an ignition portion. The tube includes a premixing chamber for mixing air for combustion and fuel to generate a pre-mixed air-fuel mixture, a combustion chamber for combusting the pre-mixed air-fuel mixture to generate post-combustion gas, and a discharge port for discharging the post-combustion gas. The ignition portion ignites the pre-mixed air-fuel mixture in the combustion chamber. The tube further includes a swirling flow generation unit arranged upstream of the premixing chamber for generating a swirling flow of which the center direction corresponds to a fuel injection direction and a diffusion unit arranged downstream of the swirling flow generation unit in the premixing chamber for diffusing the fuel incorporated in the swirling flow.
