PATENT OFFICE.

This invention relates to those methods of gas preparation in which, in addition to the water generator, the injector for hydrocarbon oils and the fixing chamber, as is known in the Lowe-Procefs, a retort chamber with retorts open at one end and filled with bituminous coal is used which is distilled by the heat of the generator gas, whereby the coal gas is mixed with the water gas and the coke is finally consumed in the generator. In the apparatuses in use up to now, the retort chamber is arranged in such a way that the gases from the ^{generator and} the retorts pass into and through the chamber on their way through the fixed chamber, and therefore no combustion is possible in the retort chamber.

When blowing on such an apparatus, the gases in the retort chamber and in the fixir chamber burned, leaving air, in various places to mix with the Gases is introduced. Since the complete combustion here depends on the gas supplied Depends on the amount of air, a very precise adjustment of the air flaps is necessary, to bring about a comparatively perfect combustion in the various chambers.

The essence of the present invention lies in the connection of a generator and Fixir chamber with a retort chamber and a number of gas channels, one of which or several lead into the retort chamber and one or more lead into the fixation chamber, so that the gas supply to each chamber takes place separately and each independently of the other is. If you provide such a retort chamber with a special exhaust pipe for the gases, some of the gases can be passed through the chamber and burned in it, while the rest is stored. Then becomes the gas exhaust pipe of the retort chamber arranged so that direct suction takes place through the retort chamber, Firstly, the endeavor of the gases to sweep backwards out of the retort chamber and mixing with the gases going to the fixture chamber is prevented, and secondly, by suction, the gases are removed pulled out of the retorts and the generator and prevented them from opening the retorts and generator doors to step outside through them.

The invention also consists in that the gas line to the retort chamber with a Provides slide through which the amount of gas to be introduced into the chamber at will can be regulated.

Furthermore, the invention consists in that the beginning of the gas lines leading to the Fixir chamber lead, attaches above the lines leading to the retort chamber, whereby the rich coal gases must enter the fixir chamber directly, while the generator gas enters the retort chamber.

The attached drawing shows: Fig. Ι a longitudinal section through the entire apparatus along the line \ - \ in Fig. 6, Fig. 2 shows a cross section according to xx in Fig. 4 through the gas ducts and the slide, 3 shows the same section with the slide open, 4 shows a plan of the retort chamber with a partial section, the one leading to the chamber Depicting gas duct with slide, 5 shows the same view with the slide open, Fig. 6 is a horizontal section along line T-J ^ in Fig. I, Fig. 7 is a view showing the new arrangement of the gas supply line, and 8 shows a section according to xx, FIG. 4. A is a generator of known design, B is the retort chamber, C is the fixture chamber, DD are retorts, which are provided with doors d ¹ at their filling ends, but are open at their inner ends d. E is a wall through which the 'retort chamber is divided into two parts, one of which receives the retort itself, while in the other part / d open out the open ends of the retort. Bridges F and G force the gases to sweep up and down and then up again around the retorts, finally making their way to the chimney ff. H ¹ is a device by means of which a jet of steam is directed towards the chimney in order to increase the draft. KK ^l K ² and K ³ are air channels through which blower air can be driven. L is the beginning of an air channel which leads from the generator and the chamber J to the retort chamber; As can be seen from the drawing, the air enters in the horizontal direction, then goes down to L ¹ and then up again to enter the retort chamber at L ^2. M is a slide which regulates the gas entry into the retort chamber; M ¹ is the handle on the slide rod. NNN ¹ are gas channels which lead from the generator and the chamber J to the inlet opening O of the fixture chamber. These channels N lie above the channel L. P is the inlet opening of the hydrocarbon oil and R the opening through which the gas exits the fixture chamber. To put this apparatus into operation, a coal or coke fire is lit in the generator and the retorts are filled with bituminous coal; Then blown air is passed through the pipe K into the generator, and the slide M is set so that the upright gases enter the retort chamber and the fixed chamber in a suitable ratio through the channel L and the channels N. The gases in the retort chamber are ignited by the blown air coming from the appropriately attached tubes K ¹ and AT ² and the combustion products finally escape through the chimney H. The gases passing through the fixture chamber are also ignited by the blown air coming from the pipe K ^s. As soon as the retorts remains hot, they will be at their open ends ■ d emanating carbon gases that mix with the gases coming from the generator and then press through the channels L and N. Now all parts of the apparatus sufficiently heated, so the tubes K and K ³ are closed 'then steam is passed, at a ^l in the generator and inserted in P oil at the head end of the Fixirkammer. Because the water gas is now richer than the gas generated during warm blowing, the opening of the channels L is correspondingly reduced by pushing the slide M closed and further blower air is introduced into the retort chamber through the channels K ¹ K ^2; the burnt gases escape through the chimney H. The heat of the retort chamber is thus maintained at its highest efficiency, and as the channels N are above the channels L , the rich coal gases will pass directly into the fixture chamber. If one wants to open the generator or the retort door d ¹ , the slide M must be opened completely so that the draft of the chimney H, which can still be supported by the steam stream H ¹ , creates a vacuum in the generator and in the chamber J as far as possible produced so that the doors can be opened without danger of the gases striking back. ■ Patent claim: In the case of a water gas generator (A) with a fixed chamber (C) the arrangement of a retort chamber (B) in which the retorts (D) charged with bituminous coal let the developed coal gas flow out into the chamber (J) above the generator, from where it flows through the ducts (LL ¹ L *), which are provided with an adjusting slide (M) and lead to the retort chamber and are passed through the gas ducts (N) to the fixture chamber (C) , as well as the arrangement of air supply ducts (K ¹ K ² ) and (KK ³ ) to burn the gases.
