Improvements in the Construction of Steam Boiler and other
Furnaces.
We, URBAN BLEIER of Hollingen Wolfsbach 9, Zurich and JOSEPH MORATH,
of Rue de Torient 3, Vevey, both in Switzerland, Manufacturers, do hereby declare
the nature of our said invention and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement.
The object of our invention is to construct furnaces for steam boilers and the
like, in such a manner as to enable heat to be applied to the feed water, or other
water which may be requned to be heated.
In accordance with on invention we construct a cast nou cellular grate, having
passages for air and water formed therem, and also (in some cases) hit a coil of
pipes on each side of the gate, through which the water to be heated is caused
to circulate.
And in order that our said invention may be particularly described and ascertained,
reference is hereby made to the accompanying drawings, in which similar letters
of reference indicate corresponding parts.
Fig. 1 is a horizontal section on the line ww of Fig. 3.
Fig 2 is a plan view, partly in section, on the line
Fig. 3 is a section on the line er of Fig. 1.
of Fig 4.
Fig. 4 is a vertical section on the line yy of Fig. 2.
The cast iron grate 18 formed with vertical air passages A, A, through which
air, passes upwards to the fuel. Water passages B, B, are also formed therein,
RS shewn The holes formed by the core pints are tapped to receive sciew
threaded plugs n n which afford means of access for cleaning out the passages B, B.
The feed water enters at C: passes along the passages B, B, as shown by
the arrows in Fig 1 and passes out in a highly heated state at D, either to the
boiler or otherwise, as required.
In some cases we fit a coil of pipes, as shown in Figs. 2 and 4, the pipes being
connected with the passages at D, whence the water ascends to the tubes E, F,
and G, round thure sides of the furnace. When the water arrives at H, it ises
into the coil K, travelling in a contrary direction round the furnace, and so on
through the coils L and M, finally leaving the coils at R.
Instead of using a cast iron giate, as shown, we sometimes form the same with
a series of pipes, connected together in any convenient manner, and with inlet and
outlet pipes.
Ilaving now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim 19
-
1. In steam boiler and other furnaces, the application and use of a grate formed
with suitable air passages and a continuous series of water channels, substantially
as aud for the purposes herein before described and illustrated by the drawings.
2. In steam boiler and other furnaces, the application and use of a fire grate as
last aforesaid, in combination with a coil of tubes, substantially as and for the
purposes herein before described and illustrated by the drawings.
