Improvements in or connected with Oil Vapour Burners for Boiling
and Heating Purposes.
We, WILHELM LUECHAU, Engineer, and FRANCISCO JAVIER DE GISBERT,
Engineer, both of Hamburg, Hohe Bleichen No. 10 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:-
Our invention relates to improvements in gas generating burners for boiling and
heating purposes, the objects we have in view being to render the combustion of the
petroleum or like liquid used in such burners entirely noiseless, to suppress all smell,
to increase the calorific effect, and produce a smokeless flame. The way and manner
in which we carry out our invention will be readily understood by means of the
accompanying drawings in which :-
Fig. 1, is a vertical section of the improved burner;
Fig. 2, is a vertical section of the cap or air-mixing chamber removed from the
head of the burner;
Fig. 3, is a cross section on line A. B. Fig. 1;
Fig. 4, shows a modified form of the burner, and
Fig. 5, is a cross section on line C. D. Fig. 4.
The head of the burner consists of two chambers b and c. c is the gas generating
chamber in which the gas is produced from a liquid combustible such as petro-
leum or the like; while b is the chamber where the gas generated is diluted or
thoroughly mixed up with hot air before being inflamed at the openings o.
Figs. 2 to 5.
The burner is put in operation as follows:-The body of the burner a, b, c, is
first heated by a small quantity of spirit such as alcohol or equivalent which is
inflamed in the small cup or vessel d. After this has been done the liquid
combustible petroleum or the like, is forced up by means of an air pump or by its
own pressure in the well known manner from a reservoir not shewn in the drawings
through the ascending pipes s to the body of the burner which has been heated
as described, the liquid material being by this means transformed or converted
into the gaseous condition. The gas thus generated within the chamber c called
the gas generating chamber, attains considerable tension, and is driven out in a
continuously fine jet from the discharge pipe e. Figs. 4 and 5.
In the well known form of burners of similar construction, this gas jet is inflamed
at e, Fig. 5, but this is not the case with our invention. In the construction now
described the jet of gas streams through the tube i into the chamber b drawing
in air with it, like an injector and in this manner becoming mixed up or diluted with
air of high temperature in the chamber 6, from which it escapes through the burner
holes o where it is inflamed; Fig. 3.
The flame or flames is or are of a blue color, and yield part of their heat to the
ring or flanger which transmits heat to the plate a and to the other parts of the
burner and also to the chambers b and c. In Figs. 1-3, the gas generating chamber
is shewn as a straight tube of horizontal direction which is connected to the
similarly straightened ascending tubes as shewn. The two ends of this tube are
closed by screws f which when removed allow the tubes to be conveniently and
easily cleaned. The mixing chamber & which forms a cover to the head of the
burner can be easily removed. In Fig. 1, it is kept in position by its own weight
and in Figs. 4 and 5, it is forced over the chamber c like a cap or case, and is kept

page_text: in place by friction. It may however in some instances be secured by screws or
the like in order to make a more satisfactory joint, and permit a ready access to the
internal interacting parts of the burner for the purpose of cleaning or repairing the
same.
Having 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 is :-
1. The combination in or with a burner for generating gas or vapourizing
liquid material such as petroleum and the like of a removeable cap or case b in
which the products of combustion are diluted and admixed with heated air, the
injector tube i passing through the gas jet, and the burner openings o on the
circumference of the cap or cover mounted upon the head of the burner, the respec-
tive parts co-operating for effecting the purposes described.
2. The combination in or with a burner for vapourising or gassifying liquid
materials as described in Claim 1, of the ring r, which when heated by the flames
issuing from the orifices o transmits heat to the plate a in close connection with it,
these parts assisting in the vapourisation of the gas passing through generating
chambers and b.
3. In a burner for vapourizing liquid combustible materials, the particular
combination of the tube e conveying the already heated and inflamable vapour from
chamber c to the heated air mixing tube i communicating with chamber b, the
respective parts co-operating for effecting the purposes described and set forth under
Figs. 4, and 5.
