Description

one

The invention relates to the coke industry, in particular to coking ovens, preferably low-coking and non-coking coal.

Known coking ovens, preferably weakly caking and non-coking coals, contain vertical heating chambers with heating walls placed on both sides of the heating chambers and regenerators.

Known furnaces do not provide sufficient efficiency and intensification of heating.

The purpose of the invention is to improve the efficiency of the furnace and to desaturate the heating intensity.

The distinction of the proposed furnace lies in the fact that in the coking chambers there are dispersers of refractory material, arranged, for example, in a checkerboard.

These dividers play the role of an intensifier of the coking process: the coal charge loaded into the coking chamber, moving downwards, falling on the dividers, continuously changes direction, and an intense non-displacement of the more heated coal at the walls with a less heated center is increased. loading, and the investigator and the process of coking.

FIG. 1 shows an oven, a domestic look; in fig. 2-longitudinal section of the furnace through the heating

pier and regenerator; in fig. 3 is a cross-section along the battery of furnaces, LL in FIG. 2; in fig. 4 is a section along the .B-B in FIG. one.

The vertical chamber furnace consists of heating chambers 1 and heating nrostenkov 2, located on both sides of the coking chambers. The heating chambers / in the lower part are combined in pairs and form an extinguishing zone 5- Over the entire height of the coking chamber / in the chessboard

4 are installed, made of the same material as the coking chamber. In the upper part of the coking chamber / there is a crepe 5 to install the boot device (not shown in the drawing),

and in the lower part, an opening connecting two chambers to install a discharge device (not shown in the drawing). The heating piers 2 are divided, however, by the length of the non-enclosures 7 into the vertical heating channels 8. Under each outgoing pillar there are horizontal precast distribution channels 9, 10 for supplying air and discharging the combustion products.

For the utilized heat waste of burning products and preheating the air entering the heating walls, generators 11 are provided at the end of the furnace, filled with a grid nozzle.

In the lower part of the furnaces, horizontal channels 12 are provided for removal of tushePI gas and channels 13 for removal from IICULM: jaaon, and coal that is produced during coking.

The technological process of coking in vertical furnaces of the proposed design is as follows.

Coal through the opening 5 load n heating chamber /. As it descends from top to bottom, the coal heats up to about 1000 ° C due to the heat of the heating walls. When it comes to the dividers 4, coal will continuously change the direction, as this happens, and the coal mixes, which ensures a uniform warming up over the width of the coal loading chamber. The rate of movement of the coal mass is controlled by dispensing the finished coke through the discharge device. The gases evolved during the coking of the coal are removed from the furnace using a gas blower (not shown) through the channels 13. The coke formed enters the quenching zone 3, where it is quenched with steam or inert gases. Gases for coke quenching are supplied to the lower part of the chamber through unloading devices and sucked them through horizontal channels 12. The heating of the furnaces is carried out by burning in the vertical heating channels 8 of the heating walls of the 2 coke oven gas. Coke oven gas is supplied through the gas supply channel. /, Where gas is distributed through the vertical heating channels 8. Air,

heated in regenerators / L enters the horizontal collecting and distributing drip, and then into the vertical heating channels 8.

Combustion products from the vertical heating channels 8 enter the collecting and distributing channels 10, then the regenerators and through the chimney (not shown) are discharged into the atmosphere.

Subject invention

A coking furnace, predominantly weakly flowing and non-coking, containing vertical heating chambers with

heating walls placed on both sides of the heating chambers and regenerators, characterized in that, in order to increase the efficiency of the furnace and intensify the heating, there are dispersers in the coking chambers

of refractory material, for example, installed in a checkerboard pattern.
