Abstract
Apparatuses and processes for forming powder are disclosed. The apparatus includes a chamber having a head plate and an array of aerosol and burner nozzles attached to the head plate for generating aerosols and flames respectively. Powder is produced by atomizing a liquid composition to project an aerosol of droplets into the chamber and heating the aerosol with flames projected by the burner nozzles.
Claims21
An apparatus for producing powder, the apparatus comprising:
- a chamber having a head plate;
- an array of nozzles attached to the head plate, wherein the array of nozzles includes at least four aerosol nozzle for introducing an aerosol of droplets into the chamber and at least two burner nozzles directly adjacent each aerosol nozzle for projecting flames into the chamber and wherein the aerosol and flames are oriented in the same general flow direction;
- and
- an exit port connected to the chamber which allows produced powder to exit the chamber.
1 more element
A process of forming a powder, the process comprising:
- atomizing a liquid composition to project an aerosol of droplets having a flow direction into a chamber through at least four aerosol nozzle wherein the chamber includes at least two burner nozzles that are directly adjacent each aerosol nozzle and that each project a flame that is adjacent the aerosol of droplets and oriented in the same general flow direction as the aerosol of droplets and wherein the liquid composition contains one or more dissolved or suspended precursors and the flames provide heat to convert the aerosol of droplets to a powder.
