Process and device for injecting a matter in fluid form into a hot gaseous flow and apparatus carrying out this process

摘要

This invention relates to a process and device for injecting at least one stream of a fluid matter into a hot gaseous flow, such as a plasma jet. According to the invention, said hot gaseous flow has the shape of an envelope of revolution communicated thereto, and the nozzle for injection of the stream of fluid matter is dispsoed coaxially to the axis (X-X) of said envelope of revolution. The invention is more particularly applicable to plasma chemistry.
