IMPROVEMENTS IN MEANS OR APPARATUS FOR EFFECTING THE
COMBUSTION OF INFLAMMABLE PULVERULENT SOLIDS AND OF INFLAMMABLE GASES
AND LIQUIDS."

It is well known that if a jet or blast of air be brought into contact with com-
bustible pulverulent matter, or with gases or liquids, the said pulverulent matter
or gas or liquid will become mixed with the said jet or blast of air and be carried
away thereby.
Now this Invention consists in a novel application of the above principle, and
in utilizing the combustion of the inflammable jet produced for the reduction of
ores, the heating of air, the puddling of iron or steel, or the heating of liquids,
the said jet being applicable either for heating, reducing, or oxidizing, as
required.
For effecting the total combustion of inflammable liquids according to this Inven-
tion two pipes are used, the ends or nozzles of the said pipes opening one against
the other. One of the said pipes, herein-after called the "liquid pipe," conveys
inflammable liquid from a tank or reservoir containing such liquid; the other
pipe, herein-after called the "blast pipe," conducts a blast of air from suitable
blowing machinery. The nozzle or aperture of the blast pipe is disposed perpen-
dicularly to the nozzle or aperture of the liquid pipe, or the two pipe ends are
placed so as to form a certain angle one with the other, and by means of a screw
or other suitable mechanical arrangement the relative inclination of the two
pipe ends may be varied, and also the relative proportions of air and liquid
supplied.
For effecting the complete combustion of pulverulent matters or gases two
concentric pipes are used. The inner or blast pipe terminates within the nozzle
of the outer pipe, which pipe is of such diameter as to leave an annular space
between the two pipes and tapers towards the said nozzle. The said outer pipe
is in communication with the reservoir or vessel containing the gas or pulverulent
matter it is intended to burn.

page_text: The blast of air from the blast pipe draws and drives out the said gas or pul--
verulent matter, producing therewith an inflammable jet, which when ignited may
be used for the purposes herein-before mentioned.
The jets may be arranged in series.
When inflammable liquid is used the said liquid may be contained in a reservoir
or vessel at any suitable distance from the spot where the jet is to be produced.
A constant level is maintained in the said reservoir or vessel, the liquid being
conveyed to the furnace or other place where it is to be used by pipes in com-
munication with one or more nozzles, the apertures in which are at a rather higher
level than the level of the. liquid in the reservoir or vessel to prevent the said liquid
from being able to flow out of itself. The suction produced by the blast of air
draws the said liquid up to the opening of the pipe end.
The blast may be either hot or cold.
