Before the charge is introduced the furnace is preheated with the plasma to a temperature of around 1600°C. The plasma itself runs from a plasma torch, which is a water cooled metallic device that uses electrical energy to ionise gas and create a plasma arc. A plasma arc is a very intense, flexible heat source with a high temperature capability.
Method for recovering elements from printed circuit boards, wherein the method comprises a step (S3) of melting the printed circuit boards (2), as well as a step (S4) of refining or purifying the melted printed circuit boards (2), characterised in that the method further comprises a step (S1) of removing organic material, such as plastic, from the printed circuit boards (2) before the …
Plasma torch technology as USPR and Plasma Arc Technologies have jointly implemented shows promise in solving that problem. If this is the case, their Plasma Torch recovery system will be operational in the near future.
The Technology Behind Plasma Torches. The core components of a plasma torch system include a power supply, a gas supply, and a torch body. The power supply generates high-frequency, low-voltage alternating current to initiate the plasma arc. The gas supply, typically comprised of an inert gas or compressed air, creates ionized plasma.

Your wrong on that one partnor1011, the plasma cutter I have will spit a stream of plasma with out being in contact with the conductor. Most of the new plasma machines have High Frequency non contact start, these new machines are a great candidate for CNC cutting tables. Great for cutting expanded mesh because the plasma stream is constant.

In water-cooled non-transferred arc thermal plasma torches, maximum plasma jet temperature ranges between 10,000–14,000 K. It depends on the type of gas and electric power and geometry of the torch [16]. In this kind of plasma torches, the plasma decays outside the torch, resulting in a significant temperature gradient.
