Abstract: A high power DC steam plasma torch system (S) includes a steam plasma torch assembly (1) wherein superheated steam (46) is used as the main plasma forming gas, thereby resulting in a very reactive steam plasma plume. The superheated steam (46) is injected internally directly into the plasma plume via a ceramic lined steam feed tube (25) for reducing condensation of steam before reaching the plasma plume. The superheated steam (46) flows through a gas vortex (16) which has tangentially drilled holes thereby resulting in a high speed gas swirl that minimizes electrode erosion. In the present steam plasma torch system (S), the plasma torch assembly (1) is ignited using an ignition contactor which is housed external to the plasma torch assembly (1). The superheated steam (46) is injected into the plasma plume using a water cooled steam vortex generator assembly (15).

Abstract: A metal powder plasma atomization process and apparatus comprises at least one plasma torch, a confinement chamber, a nozzle positioned downstream of the confinement chamber and a diffuser positioned downstream of the nozzle. The nozzle accelerates liquid metal particles produced by the at least one plasma torch and also plasma gas to supersonic velocity such that the liquid metal particles are sheared into finer powders. The diffuser provides a Shockwave to the plasma gas to increase temperature of the plasma in order to avoid stalactite formation at an exit of the nozzle. The process increases both production rate of the metal powder and the yield of −45 μm metal powder.

Abstract: A system for generating high pressure steam from dirty water uses a combination of submerged plasma arcs and electrical resistive heating. Dirty water from steam assisted gravity drainage, or other dirty water producing process, which needs to be converted into high pressure steam, is fed directly without any pre-treatment, into a plasma fired steam generator, powered by submerged electrodes. The combination of electric arc plasma and resistive heating is created between the submerged electrodes. The heat so generated will boil the water portion of the dirty water feed to generate steam that is collected in a steam space and then removed therefrom. The solids and other residues (residual sludge) present in the feed water settle down at the bottom of the steam generator and are removed via a blow-down stream. The plasma arcs are used to intermittently remove any scaling or solid deposits that can accumulate on the electrodes.

Abstract: A system for generating high pressure steam from dirty water uses a combination of sub-merged plasma arcs and electrical resistive heating. Dirty water from steam assisted gravity drainage, or other dirty water producing process, which needs to be converted into high pressure steam, is fed directly without any pre-treatment, into a plasma fired steam generator, powered by submerged electrodes. The combination of electric arc plasma and resistive heating is created between the submerged electrodes. The heat so generated will boil the water portion of the dirty water feed to generate steam that is collected in a steam space and then removed there from.

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 the present pelletizing apparatus, the induration of iron ore concentrate pellets is achieved in a tunnel furnace heated by plasma torches, wherein the generation of CO2 by the conventional iron ore pelletizing processes is reduced by using electricity powered plasma torches instead of burning natural gas, heavy oil or pulverized coal in burners, thereby reducing considerably industrial pollution of the atmosphere.

Abstract: A two-step gasification process and apparatus for the conversion of solid or liquid organic waste into clean fuel, suitable for use in a gas engine or a gas burner, is described. The waste is fed initially into a primary gasifier, which is a graphite arc furnace. Within the primary gasifier, the organic components of the waste are mixed with a predetermined amount of air, oxygen or steam, and converted into volatiles and soot. The volatiles consist mainly of carbon monoxide and hydrogen, and may include a variety of other hydrocarbons and some fly ash. The gas exiting the primary gasifier first passes through a hot cyclone, where some of the soot and most of the fly ash is collected and returned to the primary gasifier. The remaining soot along with the volatile organic compounds is further treated in a secondary gasifier where the soot and the volatile compounds mix with a high temperature plasma jet and a metered amount of air, oxygen or steam, and are converted into a synthesis gas consisting primarily of carbon monoxide and hydrogen. The synthesis gas is then quenched and cleaned to form a clean fuel gas suitable for use in a gas engine or a gas burner. This offers higher thermal efficiency than conventional technology and produces a cleaner fuel than other known alternatives.

Abstract: A two step process for the destruction of a precursor material using a steam plasma in a three zone reactor wherein the precursor material is hydrolyzed as a first step in the high temperature zone of the reactor, followed by a second step of medium temperature oxidation of the reactant stream in the combustion zone of the reactor where combustion oxygen or air is injected and immediate quenching of the resulting gas stream to avoid the formation of unwanted by-products. A related apparatus includes a non transferred direct current steam plasma torch, an externally cooled three zone steam plasma reactor means for introducing the precursor material into the plasma plume of the plasma torch, means for introducing the combustion air or oxygen into the combustion zone, means for exiting the reactant mixture from the reactor and means for quenching the reactant mixture located at the exit end of the reactor.

Abstract: A method for producing hydrogen and carbon powder from the plasma pyrolysis of hydrocarbons is disclosed and includes a DC n on-transferred electric arc plasma torch, a hot-wall reactor, for example lined with refractory or a graphite (slippery material), and a cyclone. The cyclone is adapted to recover heavier carbon particles and allow part of the hydrogen, unconverted hydrocarbon and lighter carbon particles to be recycled to the reactor to improve the overall yield of hydrogen. The prolonged contact with the plasma plume provides a typically complete conversion to hydrogen and carbon powder due to the hot walls of the reactor. The carbon powder leaving the plasma plume solidifies into a graphite- like powder in the reactor. A turbulence inside the reactor is adapted to prevent the buildup of soot on a reactor surface via the recycling of hydrogen, hydrocarbon gas or carbon powder or a mix of thereof to the reactor.
