The coating device includes a deposition chamber, and a loading structure configured to load an object into a position in the deposition chamber and unload the object from the deposition chamber. The coating device includes an atomization element in a bottom part of the deposition chamber, the atomization element creating into the deposition chamber an aerosol volume that includes a floating aerosol region in the top part of the deposition chamber.

Abstract: A multi-component coating apparatus that includes at least two deposition chambers. Aerosol in the chambers is adjusted to a to a non-impact state in which particles of the aerosol settle onto surfaces exposed to the aerosol a limited interaction period. The surface to be coated is transferred from the first chambers to the second chamber in a predefined period during which chemical interaction between the first substance and the second substance is enabled. The arrangement is very simple and robust, so also larger scale objects, for example in the order of vehicle or machinery components may be coated with very thin films.

The apparatus comprising a first atomizer for producing a first aerosol jet and a second atomizer for producing a second aerosol jet, each atomizer comprising an atomizing head in which the liquid is atomized into an atomized aerosol jet. Said atomizers further comprise a focusing part arranged to restrain the atomized aerosol jet for providing a punctual aerosol jet, said focusing part extending directly from the atomizing head. The first and second atomizer form an atomizer pair such that the atomizers are aligned towards each other for colliding the aerosol jets to each other.

Abstract: A burner nozzle is disclosed, comprising a nozzle body that includes a slit such that a line passage to the slit opens in an outlet face surface at the surface of the burner nozzle body. A plurality of channels is connected to the slit. A group of first channels is connected to a source of oxidizing substance, and a group of second channels is connected to a fuel source. Each of the first channels and second channels have a circumferential passage to the slit at a non-zero distance from the outlet face surface. Furthermore, each of the first channels and second channels is formed to output a directed tubular flow towards a side wall of the slit, or towards a circumferential passage in a side wall of the slit. A safe pre-mixed burner configuration is achieved. A burner and a surface treatment device incorporating the burner nozzle are also disclosed.

Abstract: Disclosed is a surface treatment device with a robust nozzle configuration. The device includes a nozzle for ejecting a primary stream of combustible substance to a gaseous atmosphere in an ejection direction; an ignition unit configured to ignite the primary stream in a point of ignition; and an impermeable shield providing a planar surface that is substantially opposite to the ejection direction and has in front of the nozzle a hole that allows passage of the primary stream. The shield is positioned between the nozzle and the point of ignition of the primary stream. The shield is advantageously dimensioned to allow simultaneous passage of the primary stream ejected from the nozzle and a circumferential secondary stream of gas from the gaseous atmosphere via the hole.
