Improvements in Coking Ovens.
I, BERNARD GRAU, of Eisenwerk Kraft, Kratzwick, b/Stettin, Germany, Manager of
Metallurgical Works, do hereby declare the nature of this invention to be as
follows:-
This invention relates to the construction of coking ovens with improved linings
formed of fireproof bricks of special shape, the object being to enable the flues
surrounding the coking shafts or chambers, of the oven, and serving to heat the
same, to be made with walls of the least possible thickness, so as to render the said
flues as effective as possible without diminishing the strength of the inner walls
thereof.
The accompanying drawing shows in vertical section a coking oven constructed.
according to this invention.
The lining of the coking shafts A, A2, A2 is formed, as shown at the left hand
portion of the drawing, of [-shaped bricks B, of refractory material, and at the right
hand portion, partly of L shaped bricks C of refractory material, these bricks serving
in conjunction with the surrounding brickwork, to form flues D which communicate
with one another through apertures B¹ C¹ in the ends or shorter limbs of the special..
bricks, and which are traversed by the gases generated in the coking process; the
said flues being also supplied with the air necessary for combustion of the gases
through separate flues E in the usual manner, the air being heated in passage through.
the flues E, as well understood.
The ends or shorter limbs S of the bricks bear against the outer or surrounding
brickwork, and thus effect an efficient staying of the lining or inner wall of the
coking chamber. For this reason it is possible to make the lining of less thickness
than otherwise without diminishing too much of its strength, whilst a more intense
heating action of the gases burned in the flues D is produced.

I, BERNARD GRAU, of Eisenwerk Kraft, Kratzwick, b/Stettin, Germany, Manager
of Metallurgical Works, do hereby declare the nature of this invention and in what
manner the same is to be performed to be particularly described and ascertained in
and by the following statement:-
This invention relates to the construction of coking-ovens with improved linings
formed of fire-proof bricks of special shape, the object being to enable the flues
surrounding the coking-shafts or chambers of the oven, and serving to heat the
same, to be made with walls of the least possible thickness, so as to render the said

page_text: flues as effective as possible, without diminishing the strength of the inner walls
thereof.
Fig. 1 of the accompanying drawing shows in vertical section a coking-oven
constructed according to this invention and Figs. 2 and 3 are sectional views of two
of the special bricks used therein.
The lining of the coking-shafts A 'A¹ A2 is formed as shown in the left hand
portion of Fig. 1 of [-shaped bricks B of refractory material, or as shown in the right
hand portion, of L-shaped bricks C of refractory material or partly of one kind and
partly of the other as shown, these bricks serving in conjunction with the surrounding
brickwork, to form flues D, which communicate with one another at the alternate
ends of the flues D through apertures, indicated by dotted lines at B and C, in the
ends or shorter limbs S of the special bricks B or C, and which are traversed by the
gases generated in the coking-process. The flues D are also supplied with the air
necessary for the combustion of the gases through separate flues E in the usual
manner, the air being heated in passing through the flues E as well. understood.
The ends or shorter limbs S of the bricks bear against the outer or surrounding
brickwork, and thus effect an efficient staying of the lining or inner walls of the
coking-chambers. It is consequently possible to make the lining of less thickness
than otherwise without unduly diminishing its strength, whilst a more intense
heating action of the gases burned in the flues D is produced.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed I declare that what I claim is :-
1. In coking-ovens, lining the coking-shafts or chambers with specially formed
bricks of [or L-shape, with the object of making the lining or inner walls of the
heating flues of less thickness, so as to produce a more intense heating effect, the
walls of the shaft being stayed in an effectual manner by means of the ends or
shorter limbs of the bricks bearing against the outer or surrounding brickwork as set
forth.
A coking-oven, having the linings of its coking shafts or chambers formed
of bricks B or C or B and C constructed and arranged as hereinbefore described
with reference to and shown in the accompanying drawings.
