Plasma thermal furnace for processing ore materials and recyclings of industrial wastes, melts of metals and alloys in structure of a site on manufacture of ferroalloys

 The most perspective way of processing of industrial wastes and receptions of alloys of metals from ore materials are plasma mine furnaces. It is connected to more full extraction of useful components and high efficiency of the furnace..
     Low power expenses for a unit of production are connected by that warmly departing gases go on heating of loaded materials, regenerative gas CO and Н2 is used repeatedly and burnt up to full СО2 and Н2О in regenerative reactions.
     Passing through a column of cold furnace feed, gas it is cleared of harmful impurity and a dust. On exit highly effective means of clearing which allows to lower quantity of emissions to a level, in hundreds times below maximum permissible is used.
     The bricketed raw material where the parity of processed materials and a reducer is picked optimum up is exposed to plasma processing, at controlled modes of processing of a material (temperature, a chemical compound of environment in volume of melting space). Warmly chemical reactions it is recycled due to a heat transfer to a loaded material. The most part of gases circulates on the closed contour, repeatedly participating during restoration. Products of processing are used in metallurgy, mechanical engineering, the building industry.
     In plasma ore-smelting furnace of "EPOS" are used patented plasmatrones of own design. Plasmatrones work on the gas taken from working space. Plasmatron may work with any gas, and also without gas. Plasmatrones have no restrictions on capacity and do not bring additional pollution in working space of the furnace.
     Use of the specified technical decisions allows to receive qualitatively new unit with the high efficiency, adequate to modern requirements as from the point of view of optimum use of energy and heat, and from the point of view of conformity to ecological requirements to safety of an environment.

     Advantages of application of the given plasma technology and the furnace:

• regeneration of thermal losses through heating of acting raw material;
• recirculation of gases in the furnace for full use of a reducer;
• use of high-temperature plasma mainly for initiation and acceleration of regenerative processes, increase of efficiency due to use of natural reducers up to two times;
• high-temperature plasma allows to operate temperature in working space of the furnace more flexibly;
• the best decomposition of waste products on chemical elements;
• cleanliness of departing gases raises;
• allows to receive synthesis - gas of the given properties both thermal and the electric power.

• reduction of metals from metallurgical waste products;
• melt of metals and alloys;
• recycling of waste products (liquid, firm, household, medical and others).

     Use of plasma circuits for recycling of domestic waste.
     More than 95 % of recycling of domestic waste products in the world are borrowed with recycling of waste products by their burning. During burning especially dangerous chemical substances - dioxin - which together with departing gases act in an atmosphere. As result - a bad ecological situation, deterioration of health of people. The most full recycling of firm and liquid waste products is reached by application of plasma circuits. So, deactivation of especially toxic chemical and bactericidal waste products is carried out in high-temperature plasma with an arch burning on a liquid bath melt, or an indirect arch. In high-temperature plasma (2500-10000 С), at the presence of active environments, at the given mode of course of process, there is a disintegration of highly toxic substances up to an atomic condition, to the subsequent formation of ecologically harmless gaseous products, liquid and firm substances, suitable for further use in the industry.
