Thermal plasma waste treatment
TLDR
This review summarizes the approaches that have been developed, presents some of the basic physical principles, provides details of some specific processes and considers the advantages and disadvantages of thermal plasmas in waste treatment applications.Abstract:
Plasma waste treatment has over the past decade become a more prominent technology because of the increasing problems with waste disposal and because of the realization of opportunities to generate valuable co-products. Plasma vitrification of hazardous slags has been a commercial technology for several years, and volume reduction of hazardous wastes using plasma processes is increasingly being used. Plasma gasification of wastes with low negative values has attracted interest as a source of energy and spawned process developments for treatment of even municipal solid wastes. Numerous technologies and approaches exist for plasma treatment of wastes. This review summarizes the approaches that have been developed, presents some of the basic physical principles, provides details of some specific processes and considers the advantages and disadvantages of thermal plasmas in waste treatment applications.read more

Microplasmas for nanomaterials synthesis
TL;DR: Microplasmas have attracted a tremendous amount of interest from the plasma community because of their small physical size, stable operation at atmospheric pressure, non-thermal characteristics, high electron densities and non-Maxwellian electron energy distributions as discussed by the authors.

Particle dynamics and particle heat and mass transfer in thermal plasmas. Part I. The motion of a single particle without thermal effects
Emil Pfender,Yung-Cheng Lee +1 more
TL;DR: In this article, the relative importance of various effects on particle motion was assessed in the context of thermal plasma processing of materials, and the results indicated that the correction term required for the viscous drag coefficient due to strongly varying properties is the most important factor; non-continuum effects are important for smaller particles and/or reduced pressures.

Multiscale Finite Element Modeling of Arc Dynamics in a DC Plasma Torch
TL;DR: In this paper, the dynamics of the electric arc inside a direct current non-transferred arc plasma torch are simulated using a three-dimensional, transient, equilibrium model, and the results indicate that the reattachment process in these operating modes may be driven by the movement of the arc rather than by a breakdown-like process.
