The invention relates to the field of production technology of fuel for use in mining smelting and roasting processes.

A method of obtaining coal briquettes (patent RF 2087527, priority 06.09.95,, IPC C 10 L 5/08, 5/48, 5/28), including dewatering of the coal slurry, forming the dehydrated coal slime briquetting and subsequent heat treatment of the briquettes at 200-700 With the coal slurry is dewatered to a moisture content of 10-35%. While the coal slurry can contain not less than 25% of conglomerating coals.

This method does not use binders, due to this reduced cost, however, if necessary, by adding fusible coals in this way improving the strength of the briquettes. In the case of adding fusible coals or in their absence, the method involves a preliminary dehydration of the coal slurry and the heat-treated molded briquettes, which increases capital costs and consumed in the production of briquettes electricity. In addition, a subsequent heat treatment of the briquettes contributes to the reduction of their strength, the possible occurrence of cracks on the surface of the briquette, which in turn is basicaudio and non-caking slime and small classes of coal (RF patent 2088636, priority 16.09.94,, IPC C 10 L 5/32), including the mixing of sludge or small classes of coal with a water-soluble binder, the dosing mixture, production of briquettes, packaging. In this way, the curing and providing thermoprotect briquettes are produced simultaneously with the heat-up phase during the combustion of the briquettes directly into a preheated furnace combustion device or coking directly into the coke oven chamber.

The disadvantage of this method is low consumer properties of the obtained briquettes. Due to the fact that the briquettes are not subjected to the drying process, they have low strength characteristics and can be cracked in the process of technology use in transportation in the combustion zone.

In addition, the consumer properties of the briquettes obtained in this way, rather unstable, because the properties of the material differ sharply from each other - fusible, low-caking and non-caking coals differ from other plastic properties, the ability to coking at high temperatures. Therefore, it is impossible to determine in advance the strength and energy characteristics of the briquettes in order to solve for the in order to ensure their nerazreshimosti during transportation from the manufacturer to the consumer briquettes are Packed, for example, in parchment, polystyrene, etc.

The presence of a packaging operation, firstly, leads to increased cost of production of briquettes, and secondly, it ensures the safety of the briquettes only during their transportation. In the process of technological use of briquettes in the oven packing quickly burns out, unprepared, crude briquettes at high temperatures will crack (as confirmed by the data given in the description of this patent). The process of cracking can lead to the destruction of the briquette, which will lead to a dramatic reduction of the time of its combustion.

It should be noted that technology use at temperatures exceeding 700oWith briquettes obtained by this method is impossible due to the high content of volatile and resinous substances which adversely affect the strength characteristics of the briquettes, as well as on the ecological parameters of the process for their preparation.

In addition, this method has a fairly narrow scope only for briquetting fusible, low-caking and non-caking slime and small classes of coal. A limitation of using this method is also related to the fact that you only use a water-soluble the x properties of briquettes by providing stable thermoprocessing characteristics of briquettes; reduction of capital costs of their production; the expansion of the functionality of the method due to the removal of restrictions when selecting a binder and a dramatic expansion of the potential source of raw materials.

This object is achieved in that in the method of obtaining heat-resistant briquettes, comprising preparing a briquetted mixture of feedstock and binder, forming briquetted mixture into briquettes, while ensuring thermoprotect briquettes are produced simultaneously with the heat-up phase during the combustion of the briquettes in the process of technological use, as a source of raw materials use carbon-containing raw material with a content of volatile substances is not more than 14% on a dry ash-free mass, before cooking briquetted mixture is performed with the selection of sieving feedstock fraction is not more than 10 mm, the composition of the briquetted mixture of 5-25% from the total mass of briquetted mixture of fusible coal or crushed petroleum coke with a content of volatile substances 25-35%, after forming the briquettes are dried and the binder use powdered or liquid binder, such as lignosulfonate, while the amount of binder in the total mass of briquetted mixture is x2">

The carbonaceous raw material use petroleum coke with a content of volatile substances is not more than 14% and/or screening of metallurgical coke and coke breeze and/or lean coal and anthracite.

Fusible coals have the value of the plastic layer Y is not less than 6 mm

A distinguishing characteristic of the fusible coals is that they have plastic layer that determines the presence of conglomerating coals adhesive properties, allowing the use of fusible coal as a binder in the manufacture of briquettes. Introduction in briquetted mixture of from 5 to 25% of conglomerating coals, along with a binder, such as lignosulfonate, helps to ensure a technologically advanced, well-formed source briquetted mixture with further obtaining a sufficiently durable molded raw briquette.

Also a distinguishing characteristic of the fusible coals is their high thermal stability during exposure to high temperatures. In conditions of high temperatures (360-460oC) is gumming conglomerating coals. Therefore, the inclusion of fusible coals in the composition of the briquetted mixture will help to ensure that when exposed to high temperature fusible ug Availability of conglomerating coals described properties allows to produce briquettes without their preliminary heat treatment (calcination) after molding. The briquettes produced by the proposed method, after drying, is ready for technology use in the furnaces.

Properties similar to properties of conglomerating coals, has a petroleum coke with a content of volatile substances 25-35. Therefore, it is possible to use instead of fusible coal petroleum coke with a content of volatile substances 25-35% while maintaining the achieved technical result. The similarity of sintering properties of conglomerating coals and petroleum coke due to the fact that petroleum coke contains fluid products and has the ability to influence the processes of pyrolysis of the coal mass. Properties of conglomerating coals and petroleum coke with a content of volatile substances 25-35% are the most similar.

The difference of this method of obtaining heat-resistant briquettes is that as a feedstock use any carbon-containing raw materials, such as petroleum coke and/or screening of metallurgical coke and coke breeze and/or lean coal and anthracite.

The basic requirement for starting materials - volatile matter not more than 14% on a dry ash-free mass, in order to eliminate the swelling of briquettes in their technology use and thereby save the CSOs binder - the main thing is that binder had adhesive properties.

The size fraction of the feedstock is no more than 10 mm, since such particle sizes are achieved optimum strength characteristics of the briquettes.

The operation of drying the briquettes after their formation allows to remove from the briquettes ballast moisture, to prepare briquettes for their technological use. Torrefied briquettes have much less tendency to form cracks and, therefore, have a higher strength characteristics compared to briquettes are exposed to technology use "raw". In addition, the briquettes after they have dried, have a much higher strength compared to the crude briquettes and retain their shape and in the process of their transportation, and their long-term storage.

The presence of the uniform requirements for starting materials - carbon-containing raw material with a content of volatile substances is not more than 14% on a dry ash-free mass, a certain part of briquetted mixture containing the normalized number of fusible binder and coal or petroleum coke with a content of volatile substances 25-35%, allows to obtain termostaattia it is in the process of preparation of briquetted mixture.

It should be noted that the effect of the binder is manifested mainly at low temperatures, and the action of conglomerating coal (or petroleum coke with a content of volatile substances 25-35%) is observed at elevated temperatures (350oC and above), until the temperature of the combustion zone of the fuel (1000-1800oC). The formation of coke framework of the fusible coal (or petroleum coke with a content of volatile substances 25-35%) occurs in the preservation of the binding properties of the binder, the latter also contributes to the coke frame structure. Plastic properties fusible binder and coal (or petroleum coke with a content of volatile substances 25-35%) will provide sufficient strength and indestructible briquette.

Optimum strength and thermal characteristics of the briquette are not in the process of their manufacture, and their use in furnaces. In briquettes furnace is lowered, and further hardening occurs as a result of exposure to high temperature fusible coal (or petroleum coke with a content of volatile substances 25-35%) in the composition of the briquette, leading to the formation of solid coke framework throughout the volume of the briquette.

In the process of lowering the briquettes is e and coking fusible coal (or petroleum coke with a content of volatile substances 25-35%) in the composition of the briquette. In the combustion zone of the furnace are already coming briquettes durable, well sintered. Sintering the briquette is throughout its volume, since the fusible coal was added to the briquetted mixture to the process of mixing and forming briquettes. Thus, in the combustion zone of the furnace receives carbon briquettes with a high "hot" (thermo-mechanical) strength, not subject to destruction.

The presence of briquetted mixture of a certain number of fusible coal (or petroleum coke with a content of volatile substances 25-35%) determines the strength characteristics of the coke oven frame and sets the most strength properties of briquettes in their technology use.

Uniform sintering briquettes with the formation of solid coke framework throughout the volume greatly improves their consumer properties, namely:

- provided a high uniform strength of briquettes throughout the volume, thus reducing the risk of cracking during operation;

- the presence (education) carbon frame provides the briquettes necessary porosity, which in turn leads to the complete burning of the briquettes in the process of their use.

When it is time to relax is the Eney 5% of the task can not be achieved.

If the total mass of briquetted mixture of fusible coal (or petroleum coke with a content of volatile substances 25-35%) more than 25% may unduly increase the cost of the briquettes. In addition, a number of conglomerating coal (or petroleum coke with a content of volatile substances 25-35%) will lead to an increase in the composition of the briquettes volatile and resinous substances. Excessive amounts of volatile substances may cause swelling of briquettes in the process of technological use and to its destruction, and an excessive amount of resinous substances will have a negative impact on the environment, the technological use of such briquettes.

To ensure sufficient bonding properties of conglomerating coals, as well as to ensure reliable and durable coke framework, resulting from the high temperatures, it is preferable to use fusible coals, in which the value of the plastic layer Y is not less than 6 mm

As werdstrasse raw materials is possible using petroleum coke with a content of volatile substances is not more than 14% and/or dropout of metallurgical coke and coke breeze and/or lean coal and anthracite coal with a content of volatile substances is not more than 14% on seat to obtain briquettes with stable characteristics determining the possibility of their further use. The possibility of use as a feedstock carbon-containing raw material with a content of volatile substances is not more than 14% on a dry ash-free mass, as well as the possibility of using as a binder, any material with adhesive properties that greatly enhance the functionality and scope of the proposed method. The presence of the drying of the briquettes before their technological use reduces the possibility of formation of cracks on the surface of the briquettes in the process of technological use, thereby increasing the strength characteristics and calorific value opportunities briquettes. No packaging operations crude briquettes simplifies the technological cycle of production and leads to lower costs for their production.

Analysis of the known technical solutions related to ways to obtain heat-resistant carbon briquettes, as well as analysis of the essential features of the present invention allows to make a conclusion about the adequacy of this invention, the criterion of "novelty."
