Specification of Letters meat.
Application filed November 10, 1916, Serial No. 130,682.. Renewed August 3, 1920. Serial No. 401,080.
To all whom it may concem:
Be it known that I, ALBERT AUG. BIRK- HOLZ, a citizen of the SwissRepublic, residing at Zurich, Switzerland, have invented a certain new and useful Improved Apparatus for Generating Illuminating-Gas, of which the following is a full, clear, and exact description.
The present invention consists of a furnace and process for heating the same for-the purpose of generating illuminating gas in vertical retorts or chambers for continuous working.
In the processes hitherto known for periodical or continuous working, the retorts were heated at the'broad side either from the top to the bottom or from the bottom to the top.
Certain disadvantages accrue from both systems. With the first mentioned system the fuel coming from the measuring receptacle or bunker immediately into the retort, is at once exposed to the highest temperature, which softens the coal and converts the same into a homogeneous soft mass, which hinders, if it does not entirely prevent, the free escape of the gases developed in the other parts of the retorts. The coal thus converted into a soft homogeneous mass has the further disadvantage that it prevents the regular even fall of the fresh coal, thus endangering the continuous working altogether. In addition to these disadvantages the pipe connections with the retort are liable to get clogged up, which is liable to retard or prevent the proper feed of fuel to the retort and is certain to retard the free escape of the gases developed.
If the retorts are heated from the bottom to the top, there is the drawback that the highest temperature is at the lowest part of the retort, and that this temperature does not by any means decrease evenly and gradually upward, so that a properly regulated heating suitable for the fractionated distillation of the coal, under no circumstances takes place.
According to this invention the retorts are heated from the center or approximately from the center of the furnace, according to the condition necessary for the kind of fuel to be gasified.
Air and gas are combined in a separate mixing chamber and are ignited as they leave the burner nozzles in the furnace. The
combustion gases pass first directly over the broad sides of the upper parts of the retorts from the bottom to the top and-pass thence through a flue provided in the furnace wall to the lower retort chamber, through which they pass in a vertical or zig-zag course from top to bottom and are then taken off to the recuperator.
By this method of heating, in contradistmction to the above mentioned systems the hottest zoneis produced in the center of the furnace, which enables the distillation of the fuel to be conducted, so that a preliminary distillation takes place in the upper part of great intensity advancing or increasing downwardly, and after the hottest zone has been passed, a gradually decreasing afterdistillation takes place in the lower part of Patented Oct. 12, 1920.
the retort. This is of great importance with continuous working, in order to enable a fractionated distillation and to insure a regular fall of the fresh fuel feed to be distilled.
In the accompanying drawings a furnace is illustrated'in which the present process may be carried out.
Figure 1 shows a retort, one half in front elevation and one half in vertical section,
Fi 2 is a vertical section on the line A of Fig. l.
Fig. 3 is a horizontal section on line 1 1 of Fig. 1,
Fig. 4 a similar section on line 22 Fig. 5 a similar section on line 33 and Fig. 6 a similar section on line 44 of Fig. 1. Y
The fuel feed takes place from an intermediate receptacle or measuring drum a in communication with the upper. end of the retort and hermetically sealed as regards the coal bunker or holder proper. Th1s receptacle a is adapted to hold sufficient coal for two or more hours distillation and supplies the same in equal measure to the retort b to that in which the coke, from which the gas has been extracted, is taken off from the lower end of the retort.
The retort c is divided into two chambers by a horizontal partition wall d. In the latter is provided a passage e for the preheated air of combustion and also a passage f for the heating gases. The former is 1n communication with a passage e leading from the recuperator, the latter passage being connected by a channel or passage f with the generator. The passages e .and f are connected together by openings, as indicated by arrows and in the said openings, burner nozzles h are arranged, which may beiclosed by removable bricks. oommunicatlon is established with the upper retort chamber 0 by a passage 9 provided in the furnace wall,
which opens into the lower space or chamber a close under the partition wall (1. The
ber. The lowest passage or flue la is in communication with therrecuperator and may be closed by movable bricks for regulating the heating. The operationtakes place in the following manner The heating gas coming from the generator passes through the channel or flue f into the passage 7 in the partition-wall d and here mixes with the preheated air of combustion coming from the recuperator and entering the channel 6 in the direction of the arrows. The mixture of air and gas passes through the nozzles h where it 1s ignited. The hot gases pass through the upper retort chamber 0 and pass then through the channel 9. provided in the furnace wall 1nto the lower retort chamber a, through which they wind from top to bottom (as indicated b arrows in Fig. 2) in a zig-zag course.
he heating gases are led off from the lower retort chamber to the recuperator, through the passage is. I
' In order to effect the proper regulation and heating the generator gas passage f,
the nozzles h, the heating gas outlets in the upper and lower furnace chambers are provided with adjustable bricks, which may be adjusted through suitable openings provided in the furnace walls.
The above described heating process is particularly adapted for uninterrupted or continuous working but it may also be advantageously adapted for periodical working, '5. e, for working in alternate periods.
