Abstract

A method of obtaining coke includes thermal treatment of disintegrated coal charge, its coking and cooling down of the obtained coke. The thermal treatment of the coal charge is effected by mixing it with the coke at a temperature of 600-1000°C at a weight ratio between the charge and the coke equal to 1.3-2.6:1 and in direct-flow regime, so that the coke is cooled down to a temperature of 150-250°C and the charge is heated to 120-240°C. After termination of the heat exchange process the coal-coke mixture is separated into the cooled coke and the charge. The heated charge is then used for coking.

A reduction in coking gamma and bypass for 35 is indicated by the result of which, in this case, conditions are excluded, which are inconvenient. - 6 -

Reducing the contamination of the surrounding medium in the case of an immediate accident results in the inlet of a gaseous process resulting in a loss of gas. For this reason, only water vapor is disposed of in the atmosphere as a result of the evaporation of moisture contained in the waste.

OVERVIEW AND OTHER INVENTIONS OF THE INVENTION

10 are removed from any of the following user-friendly descriptions. By reference to the drawing, a general schematic diagram of the best practice of the circuit is shown.

Red hot coke, coming out of the battery pack I quick fumes, line 2 directs to the accumulating bunker 3, _

Quickly disassociate and, due to the different types of telocouple and heat-absorbing components, and protect them - 7 - The operating effect of moisture from the coal mixture is cooled by the unit at a temperature of 150–250 ° C and the heater is free of charge. Heating up the good condition and eliminating the coke is relatively slow (5-7 minutes). Therefore, the heating of the solid mass of coal takes place at a sufficiently large rate, without heating the particles, treating the coal and liquefying (π или или а- а-).

Negatively slow cooling, a bit of coke does not experience thermal shock, since it has a place

15 Cooling down the method of extinguishing. This ensures a good balance of the system of the coke and zooms in on it.

When stirring with carbon sheathe in the process of heat exchange, it is protected by a soft, mechanical process.

20, moreover, it also helps to improve the quality of the coke. At the end of the exchange of carbon dioxide mixture, they must be sealed in a steam recovery unit II, for example, at a group. Just like a bakery, it takes a lot of money to eat, it has a lot more to eat.
