Metallurgical Vanyukov furnace.
Metallurgical Vanyukov furnace – autogenous smelter for processing, usually copper, copper-Nickel and copper-zinc concentrates, slags, or wastes.
It was called by the name of its inventor – Vanyukov A. V.
Melting takes place in the slag-matte bath furnace, where intensively fed oxygen-air mixture and the raw material of metallurgical production. If you want to maintain heat balance in the furnace is also supplied natural gas, liquid fuel or coal.
Due to the continuous blowing oxygen-air mixture directly into the molten bath in the furnace occurs for autogenous smelting process, i.e. the technological process, which is carried out entirely at the expense of internal energy resources, without the expenditure of extraneous sources of heat energy of fuel or electrical current. The heat released by exothermic chemical reactions in the melt furnace in the zone of sparging. Further, the heat generated in these reactions, maintains the desired temperature of the smelting process.
The melt reaches high temperatures in the range from 1200 to 1700 °C, its thermal energy can be used for heating and other needs.
Formed during the smelting matte (mixture of sulphides of iron, Nickel, copper, cobalt and other elements, an intermediate product in the preparation of some non-ferrous metals (Cu, Ni, Pb, and others) from their sulphide ores) and waste gases are continuously removed from the furnace.
Metallurgical Vanyukov furnace is one of the variants of the unit melting in the liquid bath barotraumas, its counterpart in the steel industry – furnace romelt.
The advantage of this furnace is that its raw materials can be accumulated over the decades of metallurgical waste, slag and low-grade coal, in contrast to the blast furnace, which is not able to process the waste and toxins.
Another advantage of the Vanyukov furnace is that it can be used for the disposal of solid municipal, industrial and other waste (waste from livestock farms, including poultry, tires, ash CHP, waste petroleum products, toxic and bio-hazardous waste). In such a furnace fully decompose toxic organic compounds (dioxins, furans, etc. connections).
