Improvements in Regenerators for Gas Retorts, Smelting Furnaces,
Coke Ovens, and Kilns.
I, JOHN WEST, M.Inst.C.E., of the Albion Iron Works, Miles Platting, Man-
chester, in the County of Lancaster, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement;-
naces,
My invention relates to improvements in the construction of the waste gas
and secondary air flues and passages of regenerators for gas retorts, smelting fur-
coke ovens and kilns, and has for its object to construct the vertical walls
of a regenerator independent of the horizontal divisions forming the gas and air
passages, and consists in supporting the horizontal divisions on ledges or recesses
on or in the vertical walls.
In the accompanying drawings;-
Fig. 1 is a front sectional elevation of a regenerator setting of gas retorts.
Fig. 2 is a longitudinal section through the waste gas passages and the secon-
dary air passages.
In Fig. 1 the division wall D divides the waste gas passages P from the secon-
dary air passages A; the space between the producer wall W and the division
wall D is divided into a number of secondary air passages marked A by means of
the horizontal divisions T built of bricks or tiles, and which are so arranged that
the incoming air is caused to travel in a horizontal zig-zag direction as it flows
upwards to the producer gas at G.
The space between the wall S and the division wall D is divided into a number
of waste gas passages P by means of the horizontal divisions T built of bricks
or tiles and which are so arranged that the waste gases on their descent to the
main chimney flue I are caused to travel in a zig-zag direction.
The horizontal divisions T forming the secondary air passages A do not enter
or bond with either of the vertical walls D) and W but are supported in position
by the ledges L formed in the division wall D and the producer wall W.
The horizontal divisions T¹ forming the waste gas passages P do not enter or
bond with either of the vertical walls D and S but are supported in position by
the ledges L formed in the division walls D and the side wall S. These ledges L
and L consist of bricks, tiles or splays projecting out of each respective wall, and
extend the whole length of the horizontal divisions T and T and add strength to
the division wall D and also prevent the jointing material between the vertical
walls and the horizontal divisions T and T from falling through.
The tiles or bricks forming the horizontal divisions of the waste gas and
secondary air passages may simply butt together or be joined together by tongues
and grooves as shown on Fig. 5.
The horizontal divisions T and T may also be held in position by additional
ledges placed immediately above the horizontal divisions T and T as shown in
In this manner
Fig. 3 and similar in every other respect to the ledges L and L'
grooves or recesses are formed in each of the vertical walls, and in these grooves
or recesses the tiles or bricks would rest.

page_text: These grooves or recesses may also be formed in the vertical walls by construct-
ing them at these parts with special bricks or blocks provided with the necessary
ledges or recesses as shown in Fig. 4.
This method of constructing a regenerator, not only ensures a perfectly tight
and strong division wall, but the horizontal divisions T and T¹ form effectual
stays thereto, and as the divisions T and T are not in any way bonded to the
vertical walls provision is allowed for vertical expansion or contraction and there
is practically no risk of fracture to the horizontal divisions T and T¹ or to the
division wall D consequently the tendency to produce what is known as "short
circuiting," or the drawing of air from the air passages A to the gas passages P is
reduced to nil.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1. The construction of the vertical walls of a regenerator independent of the
horizontal divisions forming the waste gas and secondary air passages.
2. The construction of the vertical walls of a generator with ledges or recesses
for the purpose of supporting the horizontal divisions forming the waste gas and
secondary air passages.
3. The improved regenerator substantially as described with reference to the
drawings.
