  • Reactive Spray Formation of Coatings and Powders
    Publication number: 20180044772
    Abstract: An apparatus and method for open-atmosphere flame based spraying employs a nozzle to preheat, pressurize and atomize a mechanically pumped reactive and flammable liquid solution through a small orifice or a nozzle and then a set of pilot flames to combust the spray. The liquid feedstock is preheated to a supercritical temperature before reaching the nozzle and is pressurized before spraying due to a reduced size of the outlet port of the feedstock flow channel relative to the inlet. A supplementary collimating, or sheathing, gas is supplied to the flow channel of the feedstock and both the feedstock and the supplementary gas are uniformly heated before spraying. This arrangement helps to avoid clogging of the nozzle and results in satisfactory control of the properties of the particulate products of the spraying procedure.
