PROVISIONAL SPECIFICATION.
Improvements in or relating to the Application of Fuel to
Furnaces.
I, RICHARD SLOANE RICHARDS of 2 Cleveland Road, Ealing in the County of
Middlesex, Merchant, do hereby declare the nature of this invention to be as
ollows:-
This invention relates to the application of the fuel used in furnaces.
The fuel which I prefer to use is coal or coke (though I may use other fuel) in
a fine state of division which I apply preferably at or near the upper part of the
furnace so that it is fired and practically burned as it falls, before reaching the
furnace bars upon which there may be a fire; however it may fall on to the grate
if preferred. The invention may be applied to various kinds of furnaces, say for
example for steam boilers, particularly the water-tube boilers of the Babcock and
Wilcox type, to gas retorts and the like.
The particles of fuel may vary in size but I find generally that the finer
they are the better is the result. The fuel may be carried by suitable hoppers,
shoots, channels or the like into the interior of the furnace at the upper part,
entering by the top or sides and preferably though not necessarily as near the top
as possible, so that the fuel falls as a finer or coarser powder into the mass of
Hame which it feeds and becomes practically consumed by the time it reaches the
bottom.
Dated this 9th day of January 1896.

Improvements in or relating to the Application of Fuel to
Furnaces.
I, RICHARD SLOANE RICHARDS of 2 Cleveland Road, Ealing, in the County
of Middlesex, Merchant, 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:-
This invention relates to the application of the fuel used in furnaces.
The fuel which I prefer to use is coal or coke in a fine state of division, though
nuts may be mixed with it or used separately-or I may if desired use liquid fuel.
The fuel is applied preferably at or near the upper part of the furnace so that it
is fired and practically burned as it falls, before reaching the furnace bars upon
which there may be a fire; however, it may fall on to the grate if preferred. The
invention may be applied to various kinds of furnaces, say for example for steam
boilers, particularly to the water-tube boilers of the Babcock and Wilcox type, to
gas retorts and the like.
The fuel may vary in size but I find generally that the finer it is the better
is the result. The fuel may be carried by gravity or otherwise through suitable

page_text: hoppers, shoots, channels or the like into the interior of the furnace at the upper
part, entering by the top or sides and preferably though not necessarily as near
the top as possible, so that the fuel falls as a finer or coarser powder into the mass
of flame which it feeds and becomes practically consumed by the time it reaches
the bottom; if however the fuel is in the form of nuts it will fall down upon the
grate.
Suitable spreaders may be placed in the path traversed in the furnace by the
entering fuel, so as to distribute it over a sufficiently large area and thus aid in
securing proper combustion; for instance angle-iron spreaders may be used, or, in
some instances the fuel may be delivered and spread by a jet of air or steam, or by
other suitable means.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is-
1. Delivering into a furnace at or near the top fuel in a stream or streams.
2. In the delivery of fuel such as described into a furnace at or near the top
means for spreading the stream or streams.
Dated this 9th day of October 1896.
