Industrial application of charcoal, through briquettes.
The history of charcoal and history of metallurgy are closely connected. Charcoal long years was unique fuel for metallurgy. The beginning of "Iron Age" IX... of VII centuries up to the middle of XVIII century, manufacture of charcoal was the developed industry. Our ancestors applied charcoal to melt of iron in furnaces and at the further improvement of steelmaking technology in domain. Metallurgy and forge business - one of the first industrial applications of charcoal. But after the invention in the middle of XVIII century, Abraham Derby of a way of reception of coke from coal, coke became the basic fuel for melt and thermal processing of metals, having superseded with this market charcoal. Today the situation on application of coal coke as fuel for metallurgy has cardinally changed.The global deficiency of coke explained by growth of consumption of raw material by metallurgists, put on a side of a stop of manufacture of lead, nickel, pig-iron, ferroalloys. Because of growth of cost of coked coal cost of coke for last two years has grown in sometimes.
Whether can replace presently charcoal coke and how fuel to meet modern metallurgical requirements? Charcoal on a number of parameters surpasses coal coke. The maintenance of phosphorus and sulfur that is much important for metallurgy below what at coke. Also charcoal surpasses coke under the maintenance of carbon. Application of charcoal is not accompanied by emissions in an atmosphere of hotbed or toxic gases. Coke, in turn, surpasses charcoal on such parameters, as thermal ability, bulk density.
Charcoal briquettes - the fuel uniting properties of coal coke and charcoal. The chemical compound and density in briquettes are formed is artificial, and these parameters can change depending on inquiries of the consumer. Modern opportunities allow to enter into structure of briquettes components which can adjust duration of burning, reactionary opportunities of briquettes. Also the components improving qualities of selected metals and alloys can be included in structure. The decision of a problem of increasing deficiency of lumpy ore can be the briquettes comprising powder ore or a dust of ore, received at extraction. If components of briquettes will be metallic waste of manufactures, it will be the decision of a problem of dumps and the burial grounds aggravating ecological conditions around of the metallurgical and metal cutting enterprises. Consumption of coal coke grows every day.
Fuel for metallurgy is one of set of opportunities of application of charcoal. Briquettes can beapplied as a reducer at molding bronze, a brass, the cupronickel, the zinced wire, by manufacture of crystal silicon.
Whether the forest chemical industry can cope with such volume? As it was mentioned earlier, Charcoal briquettes - a product of processing of waste of a timber industry complex. Their manufacture is connected with an opportunity of largetonnage use of inevitable waste of wood raw material at preparation and its processing at cutting woods and a tree the processing enterprises (sawdust, etc.) High rate of growth of a timber industry complex which we can observe for last years, and also absence of modern highly profitable technologies of processing of waste preconditions for formation of a rawmaterial base for the organization of manufacture Charcoal briquettes.
