Description

The present invention relates to coke ovens with transverse paired mutually serving vertical fire channels.

In FIG. 1 shows a vertical longitudinal section of the furnace; FIG. 2-vertical cross section; FIG. 3-horizontal section of the heating wall.

The coke oven is equipped with two regenerators R, divided by a common fundamental overlap A, B into four parts, which makes it possible to work independently for each one individually. The regenerator is a rectangular chamber filled with refractory bricks in the nozzle, and there is a free space Z on the front and rear sides of the upper and lower regenerators, which does not allow for a strong heat of the external front walls of the regenerator. Each regenerator, separately, has two channels: from the front side — channel 8, passing into a cast iron jug W, equipped with a control valve a for air intake and exhaust of combustion products from the regenerator, and from the back side — bypass channel S, directly connected with half of the bottom distribution channel t. With the help of these last channels - bypass S and distribution from regenerators

associated with vertical firing channels Q in the heating wall, as channel S and: i serve, provided that the regenerator works on gas: channel 5 - for inlet of the combustion product B the regenerator, and the channel is for releasing them into boron F. If the regenerator lets the air necessary for burning in the firing channels, the canal .ti lets air into the regenerator, and channel 5 releases the already heated air into the furnaces, then from there into the firing channels. The purpose of the device of these channels for all four regenerators of the same heating pier is the same, with the following difference: the channel .S of the lower regenerator is somewhat longer and is connected to the second half of the distribution channel t (Fig. 2) ,. and channel 3 passes in the back of the regenerator and is connected to the middle flue F (Fig. 1). Each regenerator, separately, is designed to supply air only fifteen fire channels and, in its capacity, is able to skip the required amount of air for burning in fifteen fire channels. Two generators, upper and lower, will feed thirty fire channels; consequently, four regenerators of one furnace will feed sixty t of fire channels or the entire heating pier. Each distribution catal along the entire length of the furnace chamber is divided by partitions R into equal 14, / 5; 16, 17; 18, 19-, 20, 21; etc. (fig. 3). Each half of the distribution channel is connected along the entire length of the furnace chamber with thirty channels P, on the one hand, and thirty channels P, on the other hand. Thus, each pier encloses, on the one hand, half of one distribution channel and, on the other, half of another distribution channel. These channels are connected directly to the furnace hearth and the fire channels and serve to admit air into the fire channel and output the combustion products in the furnace; for example, in half of channel 19 along the channel R, combustion products are released, and in half of channel 20 through air channels P enter air. The gas required for combustion in the heating wall is supplied by a gas line F ,. from where it enters through the gas pipes with metal tubes and through the window / enters the fire channel. Gas logs for each pier or two. Gas is supplied to the firing. channels from both the machine side and the dispensing side (Fig. 1). There are four metal tubes for one heating wall; two from the machine side and two from the issuance side. Each pair of metal tubes is equipped with an end valve, which, when fitted, allows gas to flow into one or the other. There are sixty-two windows / along the length of the entire heating pier: thirty-one on one vine and the same on the other. To ensure that gas and air at the entrance to the firing channel Q did not meet immediately and that the resulting burning focus was slightly higher (stretched) relative to the lower base of the heating wall, there is a dividing partition d in each firing channel (Fig. 2). The heating pier is divided into sixty equal vertical channels Q and two initial semi-circular wells g (Fig. 3). In order to prevent the premature transition of the formed combustion products; from the channel along the entire height of this channel

there is a wall h separating one channel from another (Figs. 2 and 3). Combustion in the heating space occurs in a staggered order through one firing channel in another (Fig. 3). The cross denotes the ascending stream of combustion, and the minus-descending stream of combustion. Every Vg of an hour during alignment, the direction of the flow of gas and combustion products changes to the opposite: where there was a cross, there will be a minus, and where there was a minus Art, anethet has a cross. In the upper part (these fire channels, there are installed adjustment gates d (Fig. 1), which serve to control the combustion in each fire channel separately. There is a partition l for separating one pair of fire channels from the other; as each pair of channels works independently from others, for example, partition A: does not allow gas to pass from the fire channel 10 to the fire channel 12th or from 10th to 13th, etc. (Fig. 3), and the combustion products pass exclusively from the 10th to the 11th and from the 13th to the 12th and vice versa. Monitoring the burning in the fires the channels are made using inspection chambers located in the upper base of the furnaces and viewing channels P (Fig. 1). A device for lowering the temperature & gas space of the furnace chamber is that the upper part of the chamber, the arch of the furnace, is lined with brick or potter, so that a cavity N remains through which air is passed through the main pipe M and the fan. This pipe passes on one side of the coke ovens and is connected with each chamber directly to the cavity L through a pipe and, but since the air must not pass all the time during the period of coking, but approximately in between: 10-12 hours of process coking, when the temperature of the gas vault of the furnace arch is heavily caught, in order to regulate the air inlet for each chamber separately it is installed in each nozzle to the valve or automatic valve (Fig. 1). Air passing through the cavity N along the entire length of the furnace chamber and taking a certain amount of heat (heated) leaves through the pipes on the other side (an exhaust air pipe leaves each furnace chamber, not shown in the drawing) and, thus, from all furnaces in the cavity N the air goes down the pipes. The air can be collected in a common collector and used for intake into the regenerator or for other industrial purposes. Thus, without any damage to the strength of the furnace chamber walls, the roof of the furnace is cooled, bringing great economic benefits.

The movement of gases is as follows. The regenerators Ri s and 4 operate on gas, and the regenerators 7 Kv and on air. Air is sucked through the gateway -6 into the distribution box of the last rice in the regenerator. Passing the regenerator, the air through the channel S of the lower regenerators enters distribution channel 6 from the regenerator RQ, into channel J8 from the regenerator, etc., and is distributed through channels P directly to the fire chimneys Q. Combustion occurs in a checkerboard pattern. At this time, the combustion gas is supplied from the corneurs 7, 2, 5 and 4. The combustion products rise up and pass into the next fire channel, as shown by the arrow (Fig. 2), go down and through the channels P exit into half the channel 77 from which flow through channel 5 directly to the regenerator first. Having passed it and having given up heat to the latter, the products of combustion exit through the channel into the horn F. From the regenerator, air enters through channel S into half of channel 78 and is distributed through channels P to fire channels Q. At this time, gas is supplied from cornnure 2 It comes along the same fire channels Q as the air. The gas and air are burned, transferred to the next channel, double upward, are lowered down.

and through channels P, they go out into the half of channel 7P from the rear side of the regenerator and enter the latter, from where they exit in the same manner as in the first regenerator, and all the other regenerators work in the described manner for the first hour. After aligning, the direction of the flow of gas and air is reversed. The RIQ regenerator consists on gas, and the regenerator on air and, thus, the R RS R Ri regenerators become air, and the R, Rn, R, Re-regenerators on gas and after the gas are distributed are distributed along the roots of 5, 6, 7 , (5, etc.

For flue waste products, there are three boars / 1/2 connected to a common boar going to the fire tube (not shown).
