Improvements in the Method of and Apparatus for Consuming
Smoke in the Furnaces of Steam and other Boilers.
We JOHN WILLOUGHBY of Bradford Road Batley, Engineer, and ABRAHAM
GLEDHILL of Bradford Road, Batley, Clothier, both in the county of York, do hereby
declare the nature of this Invention to he as follows:-
Our invention consists in an arrangement of tubes, pipes, brickwork or other
channels formed or placed in close contact with the boilers so that the pipes or
channels become heated and the cold air is drawn into them from the back or other
convenient part of the boiler or building, and heated as it passes up the tubes or
channels, and is introduced to the boiler over the doors or at any other suitable
position, and mixes with the smoke, makes it less dense and assists in its consumption
and so saves fuel.

We JOHN WILLOUGHBY of Batley, Engineer, and ABRAHAM GLEDHILL of Bradford
Road, Batley Clothier, both in the county of York, 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:—
Our invention consists in an arrangement of tubes, pipes, brickwork, or other
channels, formed or placed in close contact with the boilers, so that the pipes or
channels become heated, and the cold air is drawn into them from the back, or other
convenient part of the boiler, or building, and heated as it passes up the tubes or
channels, and is introduced to the boiler over the doors, or at any other suitable
position, and mixes with the smoke, makes it less dense, and assists in its consumption.
and so saves fuel.
DESCRIPTION OF DRAWINGS.
Fig. 1. is a front elevation of boiler with our improved draught improver, and
smoke consumer applied.
Fig. 2. is a plan of Fig. 1. on a smaller scale. Fig. 2ª is a sectional elevation of
hot air chainber F.
A is the boiler. B are the flues in which are placed the tubes (), which are
preferably arranged to take in fresh or cold air from the outside of the building.
The tubes pass along the flues close to the boiler, by this means the air is highly
heated, it is then delivered to the furnaces G, either above the doors at D, or below
the bars of the furnace at E, where it mixes with and ignites the gases from the coal,
and at the same time greatly improves the draught.
are
In order that the air may be more highly heated, hot air chambers F, F,
provided, in the flues to which the air tubes Care connected, dampers H are provided
so that the hot air may be delivered to the furnaces either at D or E, and the quantity
of such delivery may be regulated thereby. Doors K are provided at the end of the
flues for cleaning purposes.
By the above arrangement the air supplied to the furnace can be heated to over two
bundred and eighty degrees, and so a great saving of fuel is obtained, as the smoke
is thoroughly consumed, and the gases utilized to their full extent, this principle and
arrangement is applicable for consuming the smoke and increasing the draught in the
furnaces of locomotives, steam boats, and any other description of furnaces, also in the
flues of refuse destructors.

page_text: Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed we would have it understood, that
we do not limit ourselves to the number of tubes or the form or construction of such
tubes, or to their position which may be varied, but we declare that what we
claim is
Improving the draught and consuming the smoke in the furnaces of all kinds of
boilers by heating air in tubes, chambers or channels, and supplying it to such
furnaces for the purposes shewn and described.
Dated this Tenth day of March 1888.
