Portable application of thermal plasma and are discharge for waste treatment, thermal spraying and surface treatment

Thermal plasma and are discharge have numerous useful characteristics related to their high temperature and intense radiation. Many applications have been developed. Recently, a portable twin-torch plasma arc furnace for waste treatment, thermal spraying torches, steam plasma torches, and surface treatment of low-pressure arc was developed. This paper describes the recent development of a portable application of thermal plasma and arc discharge. The portable device can treat wastes and perform thermal spraying and surface treatments on site. This technology is expected to become more attractive.
