PROVISIONAL SPECIFICATION.
Method of Heating Steam-boilers by Means of a Flame Developed
Inside the Boiler.
I, OSCAR BRÜNLER, of Braustrasse 34, Eutritzsch, Leipzig, Germaný,
Engineer, do hereby declare the nature of this invention to be as follows:-
The present invention relates to a method of heating steam-boilers, which,
besides the advantages of economy of fuel and the decreased danger of explosion,
grant the possibility of admixing gases to the steam, which tend to increase the
effect.
Other advantages of this method are the smokeless fire and the general use of
gaseous and liquid combustibles as fuel.
Fig. 1 of the accompanying drawing is the longitudinal section of a boiler and
shows the method in question.
Fig. 2 shows a modified arrangement of the boiler.
Inside the steam-boiler A burns a flame b which evaporates the water in the
interior, ring-shaped, open receptacle a where it is conducted to through the pipe.a'.
The steam escapes through pipe k. The flame may be developed in the following
manner.
Pipe c is heated red-hot, and through pipe d and canula fa gaseous, powdered, or
liquid combustible is supplied under pressure.
Pressure-air is let in through pipe e at g the pressure-air mixes with the com-
bustible supplied through pipe d and canula f, taking it into pipe c where it is
reduced into gas.
At c gas and pressure-air ignite and form the flame b. The combustible and the
pressure-air are supplied under a pressure which exceeds the steam-pressure in the
boiler A so that the flame can develop. By means of cocks in the pipes de,
the flame is regulated so as to evaporate just as much water as flows in.
With the arrangement represented by Fig. 2, the flame burns under a hood B
being in the water-space of the boiler A. The hood B is supported by the arms i,
and the water is forced out of it through the pressure of the gas, so that the flame
can develop. The rest of the arrangement is the same as in Fig. 1.
To the water inside the receptacle A any space may be assigned but in order to
obtain a large surface, the water should be distributed as much as possible.

Method of Heating Steam-boilers by Means of a Flame Developed
Inside the Boiler.
I, OSCAR BRÜNLER of 15 Braustrasse, Eutritzsch, near Leipsic, 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 :-
The present invention relates to a method of heating steam-boilers, which,
besides the advantages of economy of fuel and the decreased danger of explosion,
grant the possibility of admixing gases to the steam, which tend to increase the
effect.
Other advantages of this method are the smokeless fire and the general use of
gaseous and liquid combustibles as fuel.

page_text: Fig. 1 of the accompanying drawing is the longitudinal section of a boiler and
shows the method in question.
Fig. 2 shows a modified arrangement of the boiler.
Inside the steam-boiler A burns a flame 6 which evaporates the water in the
interior, ring-shaped, open receptacle a where it is conducted to through the pipe a¹.
The steam escapes through pipe k. The flame may be developed in the following
manner.
Pipe e is heated red-hot, and through pipe d and canula a gaseous, powdered, or
liquid combustible is supplied under pressure.
Pressure-air is let in through pipe e at g the pressure-air mixes with the com-
bustible supplied through pipe d and canula f, taking it into pipe c where it is
reduced into gas.
At c gas and pressure-air ignite and form the flame b. The combustible and the
pressure-air are supplied under a pressure which exceeds the steam-pressure in the
boiler A so that the flame b can develop. By means of cocks in the pipes de,
the flame is regulated so as to evaporate just as much water as flows in.
With the arrangement represented by Fig. 2, the flame burns under a hood B
being in the water-space of the boiler A. The hood B is supported by the arms i,
and the water is forced out of it through the pressure of the gas, so that the flame
can develop. The rest of the arrangement is the same as in Fig. 1.
To the water inside the receptacle A any space may be assigned but in order to
obtain a large surface, the water should be distributed as much as possible.
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 :
Heating steam-boilers by means of developing a flame & inside the boiler, the
flame standing under a higher pressure than the steam-pressure, substantially as and
for the purpose set forth.
