How to Ignite an Atmospheric Pressure Microwave Plasma Torch without Any Additional Igniters

An Atmospheric Pressure Microwave Plasma Torch

Microwave plasma sources at atmospheric pressure have a variety of different applications and therefore are object of intense research. This paper covers the spectroscopic investigation of an atmospheric pressure microwave plasma torch and experiments concerning the abatement of the perfluorinated compounds CF4 and SF6. By means of optical emission spectroscopy the gas temperature of a humid ai...

Spatial Characteristics and Application of Atmospheric Pressure Microwave Nitrogen Plasma Torch

Abstract. Microwave (MW) torches are typically used to produce equilibrium plasmas for various environmental or industrial applications. We use Litmas Red MW torch (2.45 GHz, 3 kW), which is able to generate plasma in a state close to Local Thermodynamic Equilibrium (LTE) in temperature range of 1000-5000 K at atmospheric pressure. We present spatial characteristics of the generated MW plasma a...

Application of Microwave Plasma Torch to Power Plant

This presentation is a pure steam-plasma torch generated by microwave energy and uses it for coal gasification in a lightweight operating system. The high temperature of the steam torch when used for fast gasification reactions of low-grade coal ensures a compact reaction system for an electrical power plant.

Efficient, Modular Microwave Plasma Torch for Thermal Treatment

A high-efficiency and high-power atmospheric pressure plasma torch has been operated in air and nitrogen by modularly combining two 2.54 GHz microwave plasma sources. Each modular plasma device uses a shorted waveguide within which the plasma is sustained. They are arranged in series so the second torch adds all its power to the output of the first torch to produce one high power flame. Total m...
