Improvements in Refuse-destructor-furnaces.
We, ALFRED JOHN LIVERSEDGE, Engineer, and BEAMAN & DEAS LIMITED,
Engineers, both of 32, Victoria Street, Westminster, in the County of London,
do hereby declare the nature of this invention to. be as follows:-
This invention has reference to refuse-destructor-furnaces.
Furnaces of this description have hitherto usually been constructed with a
charging opening, an inclined hearth, a fire grate and a clinker door all substan-
tially in the same vertical plane; but in some cases the fire bars are arranged at
right angles to the inclined hearth with the clinker door laterally disposed. In
the former case the refuse can be drawn forward from the inclined hearth directly
on to the fire grate but in the latter case the refuse must be worked forward to
a large extent by a sort of sidewise motion from the hearth to the grate. The
lateral arrangement of the clinker door as aforesaid has many advantages, as it
permits the furnace cells to be very conveniently arranged in pairs side by side
and practically independent of any other cells with which the installation is
provided.
Our invention relates particularly to cells of the kind in which the clinker
doors are arranged laterally and consists essentially in providing an auxiliary
opening in the end wall of the cell at some distance below and in line with the
charging opening, the position of the said auxiliary opening being such that
access can be had directly on to the hearth of the furnace when a door with which
said opening is provided, is opened. By the use of the aforesaid auxiliary opening.
the refuse which has been charged upon the hearth can be pushed, by means
of a suitable tool introduced through the aforesaid auxiliary opening, straight
on to the grate. Furthermore the said auxiliary opening enables other suitable
tools to be introduced for the purpose of assisting in removing the clinker from
the fire bars. It will thus be observed that in our improved furnace we provide
three openings to each cell, viz. the charging opening, the clinker opening and
the auxiliary opening which, as before stated is located at a point vertically below
the charging opening and therefore approximately at right angles to the clinker
opening.
We prefer to reduce the inclination of the aforesaid inclined hearth of the
furnace when employing our auxiliary opening and in some cases we may dispense
with the inclined hearth altogether and provide merely a horizontal hearth; the
holding capacity of the cell is thereby greatly increased.

page_text: We, ALFRED JOHN LIVERSEDGE, Engineer, and BEAMAN & DEAS LIMITED,
Engineers, both of 32, Victoria Street, Westminster, in the County of London,
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 follow-
ing statement:-
This invention has reference to refuse-destructor furnaces.
Furnaces of this description have hitherto usually been constructed with a
charging opening, an inclined. hearth, a fire grate and a clinker door all substan-
tially in the same vertical plane. In some cases however the fire bars have been
arranged at right angles to the inclined hearth with the clinker door laterally
disposed. In the former case the refuse can be drawn forward from the inclined
hearth directly on to the fire grate but in the latter case the refuse must to a large
extent be worked forward from the hearth to the grate by a sort of sidewise motion
of the tool employed by the workmen to manipulate the refuse in the furnace
cells. The lateral arrangement of the clinker door as aforesaid has the advantage
that it permits the furnace cells to be very conveniently arranged in pairs side
by side and practically independent of any of the other furnace cells with which the
installation may be provided.
Our invention relates particularly to furnace cells of the kind in which the
clinker doors are arranged laterally and consists essentially in providing an auxiliary
opening in the end wall of the cell at some distance below and in line with the
charging opening, the position of the said auxiliary opening being such that
access can be had directly to the hearth of the furnace when a door with which
said opening is provided is opened. By the use of the aforesaid auxiliary opening
the refuse which has been charged upon the hearth can be pushed, by means
of a suitable tool introduced through the aforesaid auxiliary opening, straight
on to the great. Furthermore the said auxiliary opening enables other suitable
tools to be introduced for the purpose of assisting in removing the clinker from
the fire bars. It will thus be observed that in our improved furnace we provide
three openings to each cell, viz. the charging opening, the clinker opening and
the auxiliary opening which, as before stated is located at a point vertically below
the charging opening and therefore approximately at right angles to the clinker
opening.
We prefer to reduce the inclination of the aforesaid inclined hearth of the
furnace when employing our auxiliary opening and in some cases we may dispense
with the inclined hearth altogether and provide merely a horizontal hearth; the
holding capacity of the cell is thereby greatly increased.
In order that our invention may be clearly understood and readily carried into
effect we will proceed to describe the same more fully-with reference to the accom-
panying drawings in which:
Figure 1 is a longitudinal central section and
Figure 2 a horizontal section of a portion of a cell constructed in accordance
with our invention. In the last mentioned figure the section is taken approximately
on the line 11 of Figure 1.
A is the fire grate, B the ash-pit, C the lateral clinker door, D the charging
opening, E the auxiliary opening and F the hearth.
The refuse to be destroyed is supplied to the furnace through the opening D
whence it falls on to the hearth F and is there allowed to remain for a length of
time sufficient to enable the heat to drive off any moisture the refuse may contain.

page_text: A suitable tool is then inserted through the auxiliary opening E and the refuse
thereby pushed directly on to the fire grate A where its destruction is completed.
Instead of making the inner surface of the back wall G of the cell vertical as
illustrated we may make the same inclined or curved as represented by the dotted
lines in Figure 1.
6 is the opening to the ash-pit.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is: -
1. A refuse destructor furnace provided with an auxiliary opening located at
a point vertically below the charging opening or approximately at right angles to
the clinker opening for the purpose specified.
2. A refuse destructor furnace constructed
substantially as described with
reference to the accompanying drawings for the purpose specified.
