摘要： An apparatus and method for manufacturing solid particles based on inert gas evaporation. The method includes forming a continuous gaseous feed flow, and injecting the continuous gaseous feed flow through an inlet into a free-space region of a reactor chamber in the form of a feed jet flow, and forming at least one continuous jet flow of a cooling fluid and injecting the at least one jet flow of cooling fluid into the reaction chamber. The feed jet flow is made by passing the feed flow at a pressure above the reactor chamber pressure in the range from 0.01·105 to 20·105 Pa through an injection nozzle. The jet flow of cooling fluid is made by passing the cooling fluid through an injection nozzle which directs the jet flow of cooling fluid such that it intersects the feed jet flow with an intersection angle between 30 and 150°.

摘要： A method of and system for recirculating a fluid in a particle production system. A reactor produces a reactive particle-gas mixture. A quench chamber mixes a conditioning fluid with the reactive particle-gas mixture, producing a cooled particle-gas mixture that comprises a plurality of precursor material particles and an output fluid. A filter element filters the output fluid, producing a filtered output. A temperature control module controls the temperature of the filtered output, producing a temperature-controlled, filtered output. A content ratio control module modulates the content of the temperature-controlled, filtered output, thereby producing a content-controlled, temperature-controlled, filtered output. A channeling element supplies the content-controlled, temperature-controlled, filtered output to the quench chamber, wherein the content-controlled, filtered output is provided to the quench chamber as the conditioning fluid to be used in cooling the reactive particle-gas mixture.

摘要： A plasma device for production of metal powder includes a reaction vessel, a plasma torch, a carrier gas supply unit and a cooling tube. A metal starting material is supplied to the vessel. The torch produces plasma between the torch and the metal starting material to evaporate the metal starting material and produce a metal vapor. The supply unit supplies into the vessel a carrier gas for carrying the metal vapor. The cooling tube is provided with indirect and direct cooling sections and cools the metal vapor transferred from the vessel to produce the metal powder. The metal vapor and/or the metal powder are indirectly cooled in the indirect cooling section and directly cooled in the direct cooling section. A projection and/or a recess are disposed at least on a part of an inner wall of the indirect cooling section.
