FIELD: heating.
SUBSTANCE: invention relates to methods of ignition, formation and retention of plasma consisting of gases, using catalyst. In an example of invention realisation, plasma is ignited by the gas exposed to electromagnetic radiation (in a multimode treatment cavity) with frequency between 1 MHz and 333 GHz at the presence of plasma catalyst, which can be active or passive. Passive plasma catalyst can include, for example, any object able to induce plasma by deformation of local electric field. Active plasma catalyst can include any particle or high-energy wave packet, able to transfer sufficient energy to gaseous atom or molecule in order to remove, at least, one electron from the gaseous atom or molecule at the presence of electromagnetic radiation.
EFFECT: reduction of energy cost and enhancement of thermal treatment efficiency.
