page_text: Date of Application, 12th Dec., 1898-Accepted, 28th Jan., 1899
I, HEINRICH POETTER, of 50, Ostwall, Dortmund, in the German Empire, Civil
Engineer, 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 an improved coke-oven.
The best method of heating coking-ovens, for obtaining by-products is from
above as with this arrangement the heating gases can pass to the walls of the oven
by the shortest path. The utilisation of the heat is, on account of the slow speed
at which the heating gases flow, greater than with other arrangements wherein
the said gases are conveyed to-and-fro. Furthermore, any considerable differences
of pressure in the walls are avoided.
Experiments hitherto made, however, have been unfavourable to heating from
above as in all such constructions overheating of the upper portion of the oven,
of the gas space, occurred whereby the by-products were injured and the heating
and lighting value of the gas diminished.
In the arrangement which forms the subject of this invention the commencement
of combustion is effected below the level of the coke charge whereby the above
mentioned disadvantages are avoided.
In the accompanying drawing I have illustrated an oven constructed according
to the invention.
Figure 1 is a vertical longitudinal section through the oven, the left half being
a section on the line A, B and the right half a section on the line C, D) of Figure 2:
Figure 2 is a vertical section on the line E, F Figure 1.
The nozzles a through which the gas is fed to the walls extend through the
covering of the walls in such a manner that air spaces b, Figure 2, are left at their
sides, through which spaces air is conveyed for the combustion of the gas and
preferably at acute angles to ensure a better mixture taking place.
A combination of gas and air is formed under the nozzle a. The number of
burners is unlimited, so that the heating of the oven walls is quite regular whereby
decomposition is more quickly effected and the oven is rendered more durable.
A supply for each separate burner is unnecessary as the gas distribution tube c
is formed as a reservoir and delivers the same quantity to each of the nozzles.
The degree of heating of either end of the oven is regulated by suitably opening
or shutting the cocks d fitted to the two ends of the oven.
The above described burner arrangement can, of course, be employed also for
ovens heated from below.
my
Having now particularly described and ascertained the nature of 'said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
1. A coke-oven wherein the air passages above the oven and the covers of the
oven walls are pierced by nozzles a in such a manner that spaces are left at

page_text: the sides thereof through which air is admitted for the combustion of the gas
issuing from the nozzles, substantially as herein before described and illustrated.
2. A coke-oven of the kind described in Claim 1 wherein the introduction of
the gas into the gas distribution pipe c is effected from both ends of the oven
whereby by suitably opening or closing cocks d the degree of heating of the ends
of the oven can be regulated substantially as hereinbefore described and illustrated.
Dated the 12th day of December 1898.
