IMPROVEMENTS IN REGENERATIVE COKE FURNACES
Year: 1884

page_text: I ALFRED JULIUS BOULT of 323 High Holborn in the county of Middlesex
Engineer do hereby declare the nature of the said invention for "IMPROVEMENTS
IN REGENERATIVE COKE FURNACES" to be as follows :-
In the regenerative Coke furnaces hitherto the channels or flues have generally
been placed by the side of or below the furnace, the following improvements are
made The Channels for regenerating gas or air which are placed beneath the
furnaces or in front of the same, may also be placed on the top of the furnaces.
Instead of setting the same out in the manner of gratings in firebrick they may
be set out, if not with better result yet with the same result in pieces of masonry
of suitable shape whereby the surface is increased The fire-proof channels act as
refractors even without any lining merely by absorbing heat and rendering the
same.
By opening and closing one or more ordinary dampers between the channels placed
at either side and serving as regenerators, and of the flues or chimneys belonging
thereto the direction of the draught may be altered without requiring the use of
complicated apparatus such as Siemens damper or Pütsch's bell.
All that is required is that the gas and the air are first admitted from one side
into the channels at the furnace bottom or in the walls or into both are there burnt,
pass through the same and leave the furnace at the other side, and after the
direction of the draught is changed, they will follow the opposite path the second
time.
In this manner the combustion is first effected chiefly on one side the second
time chiefly on the other side of the coke furnace, and by this change the
temperature of the furnaces is maintained very evenly.

I ALFRED JULIUS BOULT of 323 High Holborn in the county of Middlesex,
Engineer, do hereby declare the nature of this invention for "IMPROVEMENTS IN
REGENERATIVE OOKE FURNACES A communication from the "Schlesische Kohlen
and Cokeswerke" of Gottesberg, Silesia, German Empire and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement :-
In the regenerative coke furnaces such for instance as described in the specification
to Letters Patent N° 59793 the channels or flues have generally been placed by the
side of or below the furnace according to this invention the following improvements
are made. The channe's for regenerating gas or air may be placed on the top of
the furnaces.
Instead of setting the same out in the manner of gratings in firebrick they may
be set out, if not with better result yet with the same result in pieces of masonry
of suitable shape whereby the surface is increased The fire-proof channels act as
refractors even without any lining merely by absorbing heat and rendering the
same.
By opening and closing one or more ordinary dampers between the channels
placed at either side and serving as regenerators; and of the flues or chimneys
belonging thereto, the direction of thes draught may be altered without requiring
the use of complicated apparatus such as Siemens' damper or Pütsch's bell.
All that is required is, that the gas and the air are first admitted from one side
into the channels at the furnace bottom or in the walls or into both; are there
burnt, pass through the same and leave the furnace at the other side, and after the
direction of the draught is changed; they will follow the opposite path the second
time.
'
In this manner the combustion is first effected chiefly on one side the second
time chiefly on the other side of the coke furnace, and by this change the
temperature of the furnaces is maintained very evenly.
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, The employment of alternate directions of draught in the channels conducting
the gases in coke furnaces in such a manner that these gases will according to the
position of the apparatus, damper or the like, pass once in one direction and next
in the other direction through the channels or flues of the furnace and so that the
channels or flues which at one time lead away the products of combustion the next
time admit the air for burning substantially as specified.
2, The placing of, the channels or flues on the top of the furnace substantially
as and for the purpose set forth.
3, The employment of pieces or fragments of masonry instead of refractory
bricks for the purpose of arranging or supplying the regenerative surfaces,
substantially.as set forth.
