Improvements in Supplying Hot Air to the Flues of Steam Boilers
and other Furnaces for Consuming the Inflammable Gases therein
and for Preventing Smoke.
JOHN THOMAS Howson, 57, Wolseley Road Lowfields, Sheffield, in the County
of York Engineer, and HENRY MILNES of 19, Wolseley Road, Lowfields, Sheffield,
in the County of York Manager do hereby declare the nature of this invention to be
as follows:-
:-
The object of this invention is to more effectually consume the gases made in the
flues of steam boilers and other furnaces thereby burning the black smoke and abating
the so-called smoke nuisance and economising the fuel. In carrying out this invention
we admit air below and before the ordinary bridge and convey it by means of pipes
or other channels which may be constructed of bricks, composition, metal, iron, or
other suitable material. These pipes or channels are for conveying the air along the
flues from the ordinary bridge to a second bridge placed at a convenient distanco
from the first bridge. This second is made hollow, so as to form a hot air chamber
and when the dense gases passing over the ordinary or first bridge are upon its
arrival at the hot air chamber or second bridge, mix with the hot air and are ignited
thereby more effectually consuming the gases and preventing the otherwise uncon-
sumed black vapour or smoke passing up the chimney the air inlet may be opened
or closed by means of a door valve or other suitable arrangement as required.
The pipes or channels for heating the air may be made to pass along the flues
several times, and may be carried forward through the hot air chamber or second
bridge and returned to the chamber as may be most suitable for the effectual and
economical combustion of the fuel.
Dated this 20th day of March 1890.

Improvements in Supplying Hot Air to the Flues of Steam Boilers
and other Furnaces for Consuming the Inflammable Gases therein
and for Preventing Smoke.
We JOHN THOMAS HOWSON of 57 Wolseley Road Lowfields Sheffield in the
County of York Engineer and HENRY MILNES of 19 Wolseley Road Sheffield
Manager, 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 in writing, and on reference to the accompanying sheet of
drawings, that is to say :-
The object of our invention is to more effectually consume the gases made in the
flues of steam boiler and in other furnaces, thereby burning or consuming the black
smoke and greatly abating the so-called smoke nuisance, and economising the fuel
used for such furnaces.
In carrying out the invention in practice we admit cold air below and before the
ordinary bridge (or at any other convenient part near thereto) which air is conveyed
by means of pipes or other channels constructed of bricks, iron, or other suitable
metal, or of other suitable composition or material; through the pipes or channels
