A spray drying system for drying liquid into powder including an elongated body and a closure arrangement at opposite upper and lower ends of the elongated body for forming a drying chamber within the elongated body. One of the closure arrangements including a drying gas inlet for introducing drying gas into the drying chamber. A spray nozzle assembly is supported in one of the closure arrangements. The lower end closure arrangement including a powder collection vessel for collecting powder dried in the drying chamber. The powder collection vessel is configured such that a blanketing gas may be directed into the interior of the powder collection vessel to blanket the powder in the powder collection chamber and thereby protect the powder from exposure to the drying gas from the drying chamber.

Systems and methods that provide or restore a coating to a component are provided. The systems and methods utilized an atomizing spray device. A slurry that comprises a fluid and ceramic particles, and a gas are supplied to the atomizing spray device. The slurry and gas are discharged from the spray device to form two-phase droplets. The fluid within the droplets evaporates to prevent the fluid from becoming part of the coating as the droplets traverse through the air and prior to impacting the surface of the component.

A spray drying system for drying liquid into powder including a plurality of processing towers each including an elongated drying chamber, a spray nozzle assembly at an upper end of the drying chamber and a powder collection chamber at a lower end of the drying chamber. The powder collection chamber of each processing tower being configured to discharge power to a common conveyor system.

The present invention involves providing a viscous fluid in a particular format and implementations thereof. In particular, a viscous slave fluid is provided in a particular format, wherein the particular format can be an end result or an intermediate result for the viscous fluid. In the case of an intermediate result, the viscous fluid in the second format may be further processed to a third format. Implementations or applications include supercharged fuel injection systems, methods, and apparatuses for internal combustion, lean-burn oil pre-mixing systems, methods, and apparatuses for liquid fuel combustion, and medical or biomedical devices, systems, and methods.

An atomizing spray device includes a housing having inlets that receive a first fluid and a slurry of ceramic particles and a second fluid. The inlets are fluidly coupled with outlets by an interior chamber that mixes the first fluid with the slurry to form a primary mixture of the first fluid and first atomized droplets of the slurry. A first outlet on a first side of the housing and a second outlet on the first side of the housing are shaped to change the primary mixture to form a secondary mixture of the first fluid and second atomized droplets of the slurry. The first outlet sprays the secondary mixture onto a first surface as a first layer of coating and the second outlet sprays the secondary mixture onto the first surface as a second layer of coating while the housing moves in a direction along the first surface.

A fluidized bed spray drying system for drying liquid into powder including an elongated drying chamber, a spray nozzle assembly at an upper end of the drying chamber and a powder collection chamber at a lower end of the drying chamber. A drying gas inlet is provided in the powder collection chamber and a drying gas outlet is provided at an upper end of the drying chamber. A plurality of cylindrical filter elements at the upper end of the drying chamber are in communication with the exhaust gas outlet for filtering drying gas borne powder from drying gas exiting the drying chamber.

An atomizing spray device includes a housing having plural inlets and one or more outlets fluidly coupled with each other by an interior chamber. The inlets include a first inlet shaped to receive a first fluid and a second inlet shaped to receive a slurry of ceramic particles and a second fluid. The interior chamber in the housing is shaped to mix the first fluid received via the first inlet with the slurry received via the second inlet inside the housing to form a mixture in a location between the inlets and the one or more outlets. The interior chamber in the housing also is shaped to direct the mixture formed inside the housing as droplets outside of the housing via the one or more outlets such that, based on a discharged amount of the first fluid in the droplets, the first fluid promotes evaporation of the second fluid as the droplets traverse from the housing toward a surface of a component.

A system may include a spray device having a body with a first liquid passage configured to flow a first liquid and a second liquid passage configured to flow a second liquid. The spray device also may include a spray head configured to output a spray of the first liquid and the second liquid. In addition, the spray device may include a multi-component container coupled to the body, wherein the multi-component container comprises a first container portion having a first outlet configured to supply the first liquid to the first liquid passage and a second container portion having a second outlet configured to supply the second liquid to the second liquid passage, and the first and second outlets are positioned in close proximity to one another.

An air assisted electrostatic liquid spray nozzle assembly having a relatively long elongated nozzle body with a spray tip and surrounding air cap disposed at a downstream end of the nozzle body. The spray nozzle assembly includes an upstream electrode for connection to a high voltage electric source, an elongated feed tube, an electrically enhancing stinger, and the spray tip which are secured and retained by the air cap in electrically conductive relation to each other such that liquid passing through liquid passages of the electrode, feed tube, stinger, and spray tip is discharged in an electrostatically charged pattern of liquid particles. The air cap is removable to permit easy removal and replacement of the spray tip, stinger, and liquid feed tube.
