Gasifying and Increasing the Heating Power of the Gases of Easily
Inflammable Liquids.
I EMIL ROHRBECK of 27 Kleinbehrenstrasse, Berlin in the Empire of Germany,
Engineer 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 the frequent attempts to construct apparatus for heating and lighting, by.
vaporizing inflammable liquids having a low boiling point, it was found to be a
serious defect that a special heating flame was required for heating the gasifying
device proper that is to say the chamber, spiral tube system or capillary
system.
The said flame was generally obtained by means of a wick from the reservoir of
the liquid to be employed, and it was observed that with most of the liquids which
must liere be taken into account, such as ligroin, naphtha, petroleum, the separation
of carbon was very troublesome and interfered with the effect. These defects are
completely obviated by the arrangement hereinafter described, wherein the gasified
inflammable material itself is utilized for heating the device which gasifies it. In
like manner the defect that the results of gasification of the liquids difficult to
vaporize, such as for instance petroleum, have heretofore not been satisfactory, which
may be explained in the first place by the condensation of the gasified liquids is
obviated by the arrangement hereinafter described.
This arrangement shows at the same time in what manner an ample quantity of
air may be admitted to the gas flame produced, such as is calculated to increase the
heating effect.
In the accompanying sheet of drawings wherein like letters of reference
indicate corresponding parts the before mentioned arrangements are represented as
follows;-
Figure 1. is a front elevation of a gasifying apparatus with a heating flame and a
pipe for supplying the air.
Figure 1 is a vertical section through Figure 1.
Figure 2. shows a side elevation of Figure 1.
Figures 3 to 7. illustrate modifications of the gasifying apparatus.
The apparatus comprises the pipe a bent to a horseshoe shape and placed with
its open ends into the liquid to be gasified, to the said pipe being joined the pipe b
which is in connection with the burner c 2 either directly or by means of the pipe c
wide below and with openings c¹ admitting air.
b
Round the pipe 6 commencing at its connection b¹ with the same, the pipe d coils
in several convolutions and terminates in the same again at 6 2.
This pipe d presents a large surface for its heating, and is therefore particularly
suitable for easily gasifying the liquid contained in it. The pipe d is provided
within the length of its coil with two valves d and d2. The former valve serves
for shutting off the rising gas, while the latter is in connection with a small
capillary pipe e which receives gas from the pipe d through the valve d 2 and
causes it to impinge, through the injector e' arranged at its free end, against the
coils d. This ejected and ignited gas, whose flame heats the large surface of the
pipe d, causes the rapid gasification of the comparatively small quantity of liquid
in this pipe. The gas developed passes from the pipe b upwards.
The initial heating of the pipe d takes place by a spirit or other flame.

page_text: In Figures 3 & 4 there is a repetition of the pipes a and b as represented in
Figure 1. with this difference that the shanks a are furnished with small horizontal
capillary pipes f counecting them, such pipes corresponding to the pipe d of Fig. 1.
In Figure 5 the shanks a are provided with a transverse pipe 9 which is in
connection with the horizontal pipe a through the small capillary pipes h, the
latter corresponding to the pipe d Figure 1.
Figure 6 shows again the shanks a in connection with the pipe 6 which in this
case is wound several times about itself and corresponds to the pipe d of Fig. 1.
Figure 7 shows three vertical pipes h terminating in the space i which has as
small dimensions as practicable. These three pipes are connected with each other
by small horizontal capillary pipes k which arrangement corresponds again to the
pipe d of Figure 1.
All the arrangements illustrated in Figures 3 to 7 like that in Fig. 1 may be
such that a portion of the liquid gasified in them will be used for heating same, or
that a special flame is employed for this purpose.
Having now particularly described and ascertained the nature of my said inven-
tion I declare that what I claim is ;-
1. In apparatus for heating and lighting by vaporizing inflammable liquids the
use of a portion of this gasified liquid for heating the gasifying device irrespective
of its kind and construction, so that this portion of the gas is conducted through a
pipe e below or to the gasifying device and is there ignited substantially as described
and shown and for the purpose specified.
2. Apparatus for gasifying inflammable liquids for heating and lighting purposes,
characterized by gasifying spaces of very small interior dimensions and very large
metallic surfaces, for instance in the form of several capillary or spiral or similarly
arranged pipes or the like connected with each other, for saving heating materials,
for increasing the sucking action and for obviating condensation substantially as
described and shown and for the purpose specified.
3. In gasifying apparatus described in the first and second claims the arrangement
of an additional pipe c above the orifice of the heating pipe b, for the purpose of
conducting more air to the gasifying flame and thereby increasing the heating
effect, substantially as described and shown and for the purpose specified.
