REGENERATOR FOR COKE-OVENS.
Specification of Letters Patent.
Patented Feb. 18, 1919.
Application filed April 7, 1917. Serial No. 160,497.
To all whom 2'25 may concern.
Be it known that I, Josnrn: Prnr'rn, engineer, a subject of the Kingdom of Belgium, residing at St-Gilles, Brussels, Belgium, have invented certain new and useful Improvements in Regenerators for Coke- Ovens; and I dohereby declare the following to be a full, clear, and exact description of the invention such; as will enable others skilled in the art to which it apperta-ins to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of thisspecification'.
This invention relates to a new arrange ment of regenerators and channels by means of which the agents of the combustion are introduced into and the combustion gases are eliminated from a group of coke ovens; this arrangement has been especially devised in order to allow, at will, either heating by means of the live gas of the coke ovens, or by means of poor gas obtained from blastfurnaces or gas-producers and previously heated, or simultaneously by means of live gas and heated poor gas.
The main feature of this arrangement is the use of two systems of regenerators located respectively under each half of the group of ovens and each comprising a central gallery filled with checker work and provided with transverse partitions so as to form a row of juxtaposed regenerator compartments, and two channels extending the whole length of the group of ovens, on each side of the central gallery. The regenerators communicate by slits or narrow passages alternately, separately or by groups, either with one of the longitudinal channels, or with the other channel. Both channels are intended for the evacuation of the combustion gases toward the chimney when the checker works of the generators are being re-heated, and. on the other hand for the arrival of the air to be heated during the heating period, when live gas is used. When heated poor gas is to be used, air is admitted in one of the channels and poor gas in the other.
In a particularly advantageous e1nbodiment of the invention, both channels are built in such a manner that they may be partially filled by checker work and serve simultaneously as auxiliary regenerators.
One of the channels may also be built outside of the masonry of the ovens, the other channel will then be either an ordinary chan nel, or a channel constructed as an auxiliary regenerator.
Another arrangement may also be used, in which one of the channels serves both as a channel and as an auxiliary regenerator, being partly filled with auxiliary checkerwork while the other channel is entirely or almost entirely filled with auxiliary checker works and is connected with an additional channel located outside of the masonry of the ovens.
In the accompanying drawings two embodiments of the invention are shown by way of example.
Figures 1 and 2 show an embodiment in which the two lateral galleries communicating with the chimney are used as auxiliary regenerat-ors while Figs. 8 and 4 show an embodiment in which one of the galleries is completely filled with checker work in order to form an auxiliary regcnerator to which an additional exterior channel is connected.
Figs. 1 and 3 are vertical sections taken in part through the center of a chamber and in part through the lateral wall of an oven.
Figs. 2 and a are horizontal sections taken respectively on AB and CDEFGH of Figs. 1 and 3. r
In the embodiment of Figs. 1 and '2, the mass of masonry under the ovens is provided with two independent systems of longitudi nal regenerators, one of these systems being traversed by the products of combustion while the other is traversed by agents of the combustion to be heated; the inversion being performed at regular intervals in a well known manner.
Each of these systems comprises a central gallery provided with partitions 1 located under the soles of the ovens. so as to form.
separate regenerators 2 and 3. In the embodiment shown, each of these regenerators is also divided in two parts by additional transverse partitions 4. On each side of this central gallery extending the whole length of the group of ovens, two galleries 5 and 6 are arranged which extend also the whole length of the masonry of the ovens and communicate with the chimney. Slits or narrow passages 7 connect the galleries or channels 5 and 6 respectively with the regenerators 3 and 2.
During the re heating period in the left hand system, the products of the combustion escaping from the sole-channel 8 reach the regenerator compartments 2 and 3, from which they escape through the passages 7 and reach the channels 6 and 5 and then the chimney.
So far as the right hand system is concerned, two difi'erent cases are to be taken into consideration according to the two methods of heating the ovens, either by means of live gas from the ovens or by means of poor gas from blast-furnaces or gas-producers.
When live gas from the ovens is used, both channels 5 and 6 are traversed by the entering air, the communication between the channels and the chimney having been interrupted. This air is distributed by the passages 7 into the two groups of regenerator compartments 2 and 3*, where it becomes warm, and reaches then the sole-channel of the ovens.
When heating by means of poor gas, the channel 6 and the regenerator compartments 2* are still traversed by the air to be heated, while the channel 5 and the regenerator compartments 3* are used for the passage of the poor gas, which is sent from the main pipe 9 by pipes 10 into the channel 5.
When heating is effected by means of live gas and poor gas simultaneously, the course of the air and of the heating gases is the same as when heating by means of poor gas only.
Figs. 1 and 2 show also an embodiment in which the lateral galleries 5 and 6 are used as auxiliar T regenerators. The lower part of these galleries is filled with checker work 11 and is divided into compartments by transverse partitions extending vertically only up to the upper level of the checker Work. The number of auxiliary compart ments is half the number of the main regenerator compartments in the central gallery. The upper part of each lateral gallery remains completely free and forms consequently a channel with large section, rendering possible a uniform distribution of the air and the gases in the various regenerators.
For the same reasons, the section of the passages 7 gradually increases toward the end opposite to the chimney. The action of the chimney is besides regulated by dampers in the usual manner.
As a result of this manner of building regenerators by means of galleries extending the whole length of the masonry of the ovens, the foundations for the ovens are very strong and solid, and able to resist the efiects of expansion.
in order to render it possible to heat the greater quantity of air necessary when the heating is efiiected by means of live gas and poor gas, the air regenerator con'ipartments 2 are of larger section than the gas regenerator compartments 3*. A damper located on the end of the channel 6 enables the flow of air to be controlled.
In the embodiment of Figs. 3 and a, the principal difierence consists in the fact that the gallery 5 is completely filled with checker work 11*. An additional channel 12 is then arranged outside of the masonry of the ovens and communicates with the channel 5 by pipes 13 to which the pipes 10 supplying the poor gas are also joined. The pipes 13 may be closed by means of valves 14.
This embodiment possesses the same advantages as the embodiment first described, with the additional advantage of increasing the volume of checker work in the auxiliary regenerators 5.
What I claim is:
1. In a group of regenerating coke ovens, two systems of regenerators occupying the whole length of the group of ovens, one of which is re-heated while the other is traversed by the agents of combustion to be heated, each system comprising a central gallery filled with checker work and provided with transverse partitions so as to form pairs of juxtaposed regenerator compartments, two channels extending the whole length of the group of ovens and arranged on each side of the central gallery and a number of oppositely disposed narrow passages connecting the pairs of juxtaposed regenerator compartments with the respective channels.

3. In a group of regenerating coke ovens, two systems of regenerators occupying the whole length of the group of ovens, one of which is related while the other is trav-- ersed by the agents of combustion to be heated, each system comprising a central gallery filled with checker work and provided with transverse partitions so as to form pairs of juxtaposed regenerator compartments, two channels extending the whole length of the group of ovens, arranged on each side of the gallery, one of said channels being partially filled and the other being completely filled with checker work in order to serve as auxiliary regenerators, the latter channel being connected by pipes with an additional channel arranged outside the masonry of the group of ovens, and a nun1- ber of narrow passages connecting the pairs of juxtaposed regenerator compartments with the respective channels.
