Abstract: An apparatus for producing metallic powders from molten feedstock includes a heating source for melting a solid feedstock into a molten feed, and a crucible for containing the molten feed. A liquid feed tube is also provided to feed the molten feed as a molten stream. A plasma source delivers a plasma stream, with the plasma stream being adapted to be accelerated to a supersonic velocity and being adapted to then impact the molten stream for producing metallic powders. The feed tube extends from the crucible to a location where a supersonic plasma plume atomizes the molten stream. The plasma source includes at least two plasma torches provided with at least one supersonic nozzle aimed towards the molten stream. The multiple plasma torches are disposed symmetrically about the location where the supersonic plasma plumes atomize the molten stream, such as in a ring-shaped configuration.

Abstract: An apparatus for thermal processing of waste having organic and inorganic components comprises at least a treatment station, a cooling station and a treated material-removal station, and at least three crucibles. The treatment station is adapted to thermally treat the organic components and/or inorganic components located in a given one of the crucibles located at the treatment station. The so-treated components in this given crucible are adapted to then be cooled at the cooling station, before the treated components located in the given crucible are removed therefrom at the treated material-removal station. The three crucibles are mounted on a turntable so that the three crucibles are each at one of the stations, before synchronously all moving to each crucible's next station.

Abstract: In a fossil fuel waste incineration or plasma gasification process, waste heat generated by combustion of waste is captured by a heat transfer fluid and conveyed to an Organic Rankine Cycle (ORC) for energy recovery. In the case of a fossil fuel-fired waste incineration system, the heat transfer fluid captures waste heat from a double-walled combustion chamber, a heat exchanger being used to cool the hot process exhaust (gas cooler). In the case of a plasma waste gasification system, the heat transfer fluid captures waste heat from a plasma torch, a gasification chamber and combustion chamber cooling jackets as well as any other high-temperature components requiring cooling, and then a heat exchanger used to cool the hot process exhaust (gas cooler). The heat exchanger may take on several configurations, including plate or shell and tube configurations.
