therefor.
HADDAN of the Firm of Herbert. Haddan & Co.,
Patent Agents 18 Buckingham Street Strand London, W.C. Civil Engineer
do hereby declare the nature of this invention a communication to me from
abroad by Constant Taillandier of 53 Rue de la Roquette, Paris, in the Republic
of France, Manufacturer to be as follows :-
This invention relates to an improved steam generator into which the water is
introduced in a very finely divided state in order that it may be instantaneously
vaporized the steam being superheated and dried in a number of spirally twisted
pipes.
The water is introduced into an inner tube surrounded by an outer tube on which
the fire plays, space being left between the inner and outer tube walls for the
development of steam from the water which passes out of minute holes in the inner
tube and impinges on the heated wall of the outer tube where it is instantly
vaporized. There may be any suitable number of these tubes side by side at small
intervals apart, and from each outer tube there rises a number of spirally wound
tubes for leading off the steam and delivering it into other cross tubes from which
branches lead to a main steam chest or pipe.
These steam generating tubes, spiral tubes and cross tubes may be all housed
within a casing in the lower part of which is the furnace, such casing being made
with double walls to receive the feed water for heating the latter before it is fed by
any suitable means to the steam generating tubes.
The furnace chamber may contain any suitable arrangement of torch like burners
for combustion of petroleum; these torches being supplied with fuel by horizontal
pipes communicating with them at the bottom and having cocks for regulating the
supply to the whole or to groups or rows of such burners.
Air is supplied through the perforated floor plate of the casing.

do hereby declare the nature of this invention a communication to
abroad by Constant Taillandier, of 53 Rue de la Roquette, Paris, in the Republic
of France, and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-

pipes.
The water is introduced into an inner tube c surrounded by an outer tube k on
which the fire plays, space being left between the inner and outer tube walls for
the development of steam from the water which passes out of minute holes
(about 2 to 3/10000 diameter) in the inner tube and impinges on the heated wall
of the outer tube where it is instantly vaporized. There may be any suitable
number of these tubes side by side at small intervals apart, and from each outer
tube there rises a number of spirally wound tubes d for leading off and drying the
steam and delivering it into other cross tubes g from which branches lead by pipes ij
to a main steam chest or pipe p.
These steam generating tubes, spiral tubes and. cross tubes may be all housed
within a casing mn in the lower part of which is the furnace, such casing being
made with double walls to receive the feed water for heating the latter before it is
fed by any suitable means to the steam generating tubes.
The furnace chamber may contain any suitable arrangement of torch like
burners a for combustion of petroleum; these torches being supplied with fuel by
horizontal pipes / communicating with them at the bottom and having cocks for
regulating the supply to the whole or to groups or rows of such burners.
Air is supplied through the perforated floor plate of the casing.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The construction of steam generator consisting of parts ckd and g substantially
as described.
2. The construction of furnace with petroleum torch burners a arranged in groups
with feed pipes and cocks as described.
3. The combination of the generator and furnace arranged and constructed as
set forth.
Dated this 8th day of May 1896.
