Improvements in Refuse Consuming Furnaces or Destructors.
I, SAMUEL JOHNSON BEAMAN, of Crosfield Street, Warrington, in the County
of Lancaster, Plate and Sheet Roller, do hereby declare the nature of this in-
vention to be as follows:-
This invention relates to furnaces or destructors more particularly intended
for consuming or destroying towns refuse and is designed to simplify the construc-
tion of such furnaces and render them capable of being erected in less space
than others that have been hitherto constructed.
The furnace is constructed with three (or more) cells completely separated or
isolated from one another by a partition or division wall. Each of these cells is
practically identical in structure and is provided with a grate or hearth an
enclosed ash pit or chamber furnished with a forced draught forming it into an
air supplying chamber. A clinkering door and a hopper or suitable inlet
through which the refuse is supplied."
The three or more cells are enclosed by an arch or each may be separately
arched.
The cells are placed side by side and preferably on the same level and at the
end is a combustion chamber with which all the cells communicate being
separated or divided therefrom by a bridge.
The bridge may be hollow to supply air. The combustion chambers may be
inclined or tapering at the back leading to the flue.
As two or more of the cells are always in full operation one only being clinked
at a time the combustion chamber is always maintained at a high temperature.
A boiler of water tube Lancashire or other construction is set behind the com-
bustion chamber to utilize the heated gases and products of combustion as they
escape.

Improvements in Refuse Consuming Furnaces or Destructors.
I, SAMUEL JOHNSON BEAMAN, of Crosfield Street. Warrington, in the County
of Lancaster, Plate and Sheet Roller, do hereby declare the nature of this in-
vention 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 furnaces or destructors more particularly intended

page_text: for consuming or destroying towns refuse and is designed to simplify the construc-
tion of such furnaces and render them capable of being erected in less space
than others that have been hitherto constructed.
It will be fully described with reference to the accompanying drawings.

Fig. 4. Transverse section on line - Fig. 2.
The furnace A is constructed with three (or more) cells B set side by side
and completely isolated or separated from each other by a partition or division
wall C. The cells B are practically identical in structure each being provided
with a grate or hearth D and enclosed ashpit or chamber E formed into an
air supplying chamber beneath the grate by the forced drought inlet pipe F.
Each cell is also provided with a clinkering door G and a hopper or inlet H
opened and closed by damper K through which the refuse is supplied to the
furnace.
The three (or more) cells B are placed in the same level and preferably en-
closed by a single arch or span L of fire brick though if desired each may form
a separate arch.
The
At the back of the three (or more) cell B is built a combustion chamber N
which is separated from the cells by bidges M and common to all.
bridges M are hollow and a supply of air is admitted through them to the
combustion chamber.
The combustion chamber N inclines or converges at the back and behind it
is set a boiler of watertube Lancashire or other construction to utilize the heat
from the products of combustion and heated gases as they escape.
Two (or more) of the cells are always in operation-only one being clinkered
at a time and the combustion chamber is always maintained at a
high tem-
perature so that a constant source of heat is always available for the generation
of steam.
The triple cell destructor furnace thus constructed presents many advantages
over those hitherto in use amongst which are the following:-
(a) A regular combustion of the refuse.
(b) Complete cremation of the fumes.
(e) A quicker charging and clinkering.
(d) Low percentage of clinker.
(e) High and regular temperature in combustion chamber.
(f) Cheap cost of burning..
(9) High and regular steam generating power specially adapted for working in
conjunction with electric installations.
(7) Low cost of erection.
(i) Economy of space.
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. A furnace or destructor for consuming refuse having the several parts con-
structed and arranged in combination substantially as described and shown.
