Creation of the equipment for introduction of power saving up technologies in industrial production and environment protection has now huge value. In world power system at set fire of coppers and stabilisation of burning of a coal dust spend approximately 50 million tons of black oil or of natural gas. A smoke gases contain nitrogen oxide, sulfurs oxide, vanadium oxide etc and to pollute environment.

Other of the most serious environmental problems facing many industrial developed countries, is environmental contamination household and industrial wastes which in most cases possess such undesirable properties, as toxicity, carcinogenicity, mutation, corrosion activity, reactionary ability and fire danger.

Advantage of use microwave of plasmatron for recycling of poisonous chemicals consists in simplicity of technological process and the process equipment, namely, in one-gradualness of process, and also in creation in the field of burning of poisonous substances of a heat (to 12000 º C). Besides, installation works with high coefficient of performance, as practically all microwave capacity is spent for combustion of substances

The important advantage microwave plasmatron is that in the course of its work liquid or firm fuel, and also account chemical materials is not used.

Microwave discharge arises in the gas filling the resonator. During approximately one micro second after inclusion of magnetron intensity of the microwave field in the regional expert output reaches apertures of the value close to strike value, is initiated unelectrode microwave discharge extending in freely soaring plasma freely to soar plasmoid. Under the influence of specially organised vortical stream of gas the plasma clot is deduced through a nozzle outside in the form of a continuous plasma stream. Plasma discharge does not contact to resonator walls owing to what metal erosion is absent. Length of a plasma stream and the cross-section sizes of plasmoid in the resonator regulated by quantity submitted of plasma formed gas.

Replacement of expensive gas and black oil on thermal power station is an actual problem.

Alternative or partial replacement of coal is the biomass (an agricultural waste, a waste of wood treatment etc.) But the problem of its use consists in high humidity of a biomass which complicates set fire an is low-temperature flame of natural gas or black oil. At use in incendiary devices gas or black oil in atmosphere emissions of harmful chemical substances arrive: oxides of sulfurs, nitrogen, vanadium.

Comparison of efficiency of use microwave plasmatrones with electro-arc

plasmatrones, which are used now, shows that the offered way of microwave plasma processing has essential advantages. The way of excitation microwave plasmolize and use of a plasma torch in incendiary device of coppers has high efficiency of thermochemical transformation of parts of fuel, does not demand use of coal electrodes with short period of validity and provides reception of homogeneous and easily controllable plasma torch. microwave plasmatrones are capable to develop high shock temperature (to 12000 ºC).

From plasma influence in a coal dust there are positive changes. Coal particles are split up for smaller components. Thanks to high concentration of energy in plasmoide very high speed of heating particle of fuel that provides effective allocation of flying components and gasification the rest of coke is reached. All it raises reactionary properties of fuel.. Thermal explosion dust-coal particles accelerates an exit of flying substances at the expense of more developed surface of reaction and occurrence of very small particles which are heating up to temperature of allocation of flying substances much faster, than big. On a photo parts of the coal dust which has been selected from a stream are represented: a - in the absence of microwave plasma; b - in the presence of microwave plasma (pictures are received by means of a raster electronic microscope). a b

The combined non-polluting way of recycling of an organic waste is an application of technology of multiplanimetric circulating plasma pyrolysis. The offered technology provides non-polluting recycling of a waste with reception high-energy, gaseous, liquid and firm of fuels.

The products received as a result of plasma-pyrolitic decomposition completely provide an independent mode of process with possibility of commercial realisation of days off high-energy of fuels, metals etc.

The greatest achievement of a way of plasma-pyrolitic gasification is molecular decomposition and utter annihilation of an organic waste, both firm, and liquid, toxic and not toxic.

As a result processed material will be transformed to combustible gases and harmless, easily flammable rests - slags. The plasma-pyrolitic method is a processing of a waste in the closed cycle where there is no open dust, there are no streams in water in any form, and there are no emissions in atmosphere.

Plasma technology of processing of the waste containing organic materials (the household dust, industrial wastes, toxic organic connections, a medical waste, the pesticides forbidden to application or with expired working life and other) allows to receive additional energy

Plasma-pyrolitic technology allows to make both one kind of a waste, and various mixes.

One of the most serious ecology problems facing to many industrially developed countries, environmental contamination household and industrial wastes which in most cases possess such dangerous properties, as toxicity, carcinogenicity, mutation, corrosion activity, reactionary ability and fire danger is. Most widely used ways of processing liquid, a powder similar and the granulated toxic waste - loading method of poison substances in special container with its subsequent burial place, burning, neutralisation poison chemical matters in fusion of alkaline reagents, thermal decomposition with use of the electroarc discharge are insufficiently reliable. In the course of burning poison chemical at not enough heats, besides nitrogen oxide and carbon, it probably the formation of such toxic waste, as phosgene, dibenzofuranes, dioxines, benzopiren, and other ultratoxic products in the quantities exceeding maximum permissible concentration. Chemical methods are high expense, and application of electroarc plasma demand enough difficult design of installation and frequent replacement of electrodes. Destruction of electrodes at their operation pollutes plasma products of erosion. Only destruction in harmless to people and substance environment will cardinally solve a problem of safe recycling of poisonous substances with transformation of poisons.

Alternative to existing technologies low temperature burning of a toxic waste is their

burning with use of microwave plasma. Use of plasma with average temperatures 3500 - 5000ºC allows to carry out the destruction of organic and inorganic connections with very big speeds and high degree of transformation.
