Abstract

A method is provided for purifying gases, particularly gases contaminated by environmentally harmful substances, by way of plasma discharge. The gas to be purified is guided through a thermal plasma, which is generated by electrodeless ignition of a process gas, so that, by way of the thermal plasma, the harmful substances contained in the gas to be purified are converted to environmentally neutral, fully oxidized substances.
