FEEDING ARRANGElWENT' FOR GAS
PRODUCERS
Joseph Daniels, Essen, Germany, assignor, by
mesne assignments, to Koppers Company,
Pittsburgh, Pa., a corporation of Delaware
Application-January 9, 1936, Serial No. 58,380

3 Claims.
The invention relates to an apparatus for feed
ing the fuel into gas producers and especially
into coal-gas producers from a fuel bunker situ
_
ated outside the gas producer by means of a
5 feeding arrangement which distributes the fuel
over the whole section of the gas producer.
The principal object of my present invention
is to provide such improvements in the feeding
arrangement of gas producers so that the fuel
10 is distributed uniformly and automatically over
the whole fuel bed in exact adjustable quanti
ties, quite independent of the quality, i. e. the
grading, composition, speci?c gravity and mois
ture of the fuel and without the segregation of
' the fuel.
The cover 3 is moved by means of a tooth wheel
8 which sits on the driving shaft 1. The tooth
wheel gears into the tooth rim 9 of the gas pro- ;
ducer cover}.
The fuel to be gasi?ed is delivered from the
stationary bunker I ll into a feeding hopper II,
which is arranged centrally upon the rotating
gas producer cover 3. A box wheel I2 is con 10
nected in a gas-tight way to the feeding hopper
II by means of which the fuel is delivered in
exactly measured quantities from the hopper H
to the feeding pipe IS. The vertical feeding pipe
13 is connected to a horizontal feeding pipe I4 15

feeding arrangements.
provided a chute I6 which is ?xed to a shaft l1
The principal feature of the invention is char
acterized by providing between the charging hole
reaching through the gas producer roof.
The feeding pipe I4 is so designed, that its
section, as shown in Fig. 1, is permanently ?lled
with the fuel which is pushed gradually through
the feeding pipe M by means of the piston l5,
whereby at every forward stroke of the piston
a part of the fuel which has been fed by the box
wheel is caught by the piston and then delivered
into the feeding pipe l4. After the quantity of 30
fuel has been fed into the feeding pipe, resulting
from the forward stroke of the piston, a corre
sponding quantity of fuel falls at the end of the

densation of vapours produced by the gasi?ca

a gas-tight horizontal feeding pipe, through which
the fuel will be led by means. of an oscillating
piston having an adjustable stroke in such a way
that the feeding pipe is permanently ?lled with
fuel during the operation.
Furthermore, there is provided according to the
present invention besides the fuel path formed
by the automatic feeder a second fuel path, be
tween the bunker outlet and the charging hole of
35 the gas producer roof. By means of this second
fuel path it is possible to feedthe fuel in ad
. justable quantities very quickly into the gas pro
ducer in order to cover if necessary any ?re on
the fuel surface and to avoid any damages re
sulting therefrom‘.
Still further objects of my invention may be
taken from the following description of a pre
ferred embodiment of my invention shown on the
45
tight sealing between the rotating cover 3 and
the stationary gas producer roof.
in which is provided a reciprocable piston l5
which suitably takes up the whole section of the
pipe M. The feeding pipe l4 ?nally leads into
the charging hole 4 of the gas producer roof:
Underneath the charging hole 4 there is also

provements in which the feeding arrangements

The gas producer shaft 2 in which is placed
the fuel bed I, is sealed at the top by a rotating
cover 3 in which is arranged the fuel charging
hole 4. The gas producer cover is supported
on rollers 5 in the stationary part of the gas
55 producer roof. A cup sealing 6 ensures the gas
20
feeding pipe through the charging pipe 4 onto
35
the distributing chute IS.
The coal plug which is permanently kept in the
feeding pipe [4 seals the fuel feeding arrange
ment against the atmosphere. Any condensa
tions which for instance are formed by the tarry
substances and which escape from the coal during 40
the gasi?cation process cannot cause any trouble
in the coal plug of the feeding pipe l4.
On the other hand, it is impossible for the
gases and vapours which have been formed in
the gas producer to escape into the open air, as 45
the coal in the feeding pipe M as well as the box
wheel 12 offers a sufficiently high passage resis
tance to the gas. The movement of the delivery
piston I5 is performed by a double lever l8, which
fits with one arm into the cutting IQ of the de 50
livery piston l5. The lever I8 is supported on a
shaft 20 which is put into an oscillating move
ment by means of an electric motor 2| by mak
ing use of the crank shaft 22 and the rod 23.
- The lever 24 is ?xed at the other end of the 55

driving shaft 20. A horizontal rod 25 is con
nected to the lever .24. A pawl 26 is ?tted to the
rod 25, which interlocks into the usual tooth rim
2'! of the box wheel in such a way, that at any
cover for the drive of the various feeding devices.
The current is supplied by a suitable sliding con
tact by making use of a pipe 42, which is ?tted
to the stationary bunker H! in the center of the
movement of the rod 25 upon a forward stroke
of the piston 15 the box wheel is moved on to a
certain extent and on retractive movement of
gas producer cover and ?xed to a hopper cross

As shown in Fig. 2, a second pawl 28 is arranged
at the other end of the rod 25, by means of
which the distributing chute I6 is set into opera
tion during the forward stroke of piston 15 and
merely idles during the retractive stroke of
15 piston 15.
A hand lever 29 is ?rmly ?xed on the upper end
of the chute shaft H, by means of which the
chute I6 can be rotated. A lever 3|] is further
loosely supported on the shaft ll, which can be
20 ?rmly coupled with the hand lever 29, by means
of the removable pin 3!. The lever 30 carries a
roller 32, which is situated within the range of
a cam plate 33. This plate is turned by the pawl
wheel 34, by making use of the worm 35, and the
25 worm wheel 36.
The cam plate 33 is so designed, that the chute
I6 can be moved by the rotation which has been
transferred from the cam plate 33 onto the lever
38, so that the end of the chute [6 during the
30 operation of the gas producer, i. e. at that time
when the gas producer cover is rotated and the
chute moved has to go the way as indicated in
Fig. 2 by dotted lines 35. Furthermore, the curve
plate has been thus constructed, that the oscilla
to U! tion of the chute can be retarded towards the fuel
bed, so that equal quantities of fuel are distributed
over every surface unit of the fuel bed.
Sometimes it happens during the operation of
brace arranged in the hopper H.
Said hopper
cross-brace carries at the same time the current
feeding cables. The sliding contacts are housed
in the casing 43, so that an easy access from out
side is rendered possible.

I have described my present invention in con
nection with the preferred embodiment thereof,
but my invention is not limited in all its aspects
to the mode of carrying out as described and
shown. The invention may be variously embodied 15
within the scope of the following claims.
