PATENT OFFICE.

The production of luminous and heating gas by dry distillation of hard coal and other such gas-yielding substances is currently only available in lying, d. H. horizontal or inclined retorts. The gassing in perpendicular standing retorts, which tried a lot in the beginning of the gas industry and also practical was carried out, has been completely abandoned for a long time, as a result of by The location and shape of the retorts caused disadvantages, primarily the inferior quality of the gas is to be mentioned.

Almost all of the standing retorts that have become known were discharged of the gas only at one point at the top, mostly through an outlet connection at the top ; the gases produced in the lower part of the retort therefore had to be the penetrate whole column of glowing gasification material before they could escape. But it was already recognized in the early days of gas technology that the high-quality, Luminous and heated hydrocarbons that develop first through prolonged contact with glowing bodies are broken down into inferior ones, whereby on top of that the extremely annoying, the efficiency of the process degrading graphite formation occurs. As a result of this knowledge one went to the now almost common practice of gassing thin layers in recumbent retorts. But the high-quality hydrocarbons must also be in horizontal or inclined retorts before they can escape Stroke the riser tubes along the overheated retort walls and place a undesirable, albeit significantly less decomposition than in vertical retorts suffer.

But with leaving the vertical retorts, their great advantage also went, namely that of the most convenient and cheapest loading and unloading lost, whichever Advantage over time, due to the rise in wages and the significant for mechanical loading and unloading devices always incur costs has become more valuable.

With the present new method there is now a practical way, the great one To achieve the advantage of using vertical retorts and the intended disadvantages a minimum that is meaningless in practice. It is for this purpose the standing retort has been reverted to with the fundamental change that the exhaust of the gases is not through a single outlet opening at the top or at the side, but through a side slot running the entire height of the retort or through several one above the other lying side openings happens, which BEZW. which with one of the heating withdrawn collecting duct are in the shortest possible connection. This achieves that the gases formed from many low

Claims (1)

Layers of the material to be gasified can quickly escape sideways without high storage Pull through layers of glowing goods and coat large overheated areas have to. You can then use standing retorts of any height without fear of the disadvantages associated with them up to now to have to. In addition, there is again the further advantage of all standing retorts over the lying retorts that their spatial content can be fully charged with gasification material, while this is the case with the lying retorts is possible at most halfway to remove the fuel layer from the The above-mentioned reasons do not become too high and the exhausting gases have enough cross-section to leave inside the retort. So there also remains the higher production capacity of the upright retort compared to the horizontal retort with the same dimensions. Standing retorts for gas preparation with lateral triggers are known (cf. German patent specification 14050 and British patent specification 5464/1890), only in these is the duct into which the side vents open, the heat of the retort furnace not withdrawn, so the arrangements described there remain those described above Disadvantages that are avoided in the present arrangement. Used to carry out the procedure one looks at the attached drawing in plan (Fig. 1) and in vertical section (Fig. 2) shown retort arrangement. R is the high, fire-bathed retort made of chamotte or other suitable material, which penetrates the ceiling of the furnace at the top and above it carries the A ^ closure A , rests on supports below and is provided with a lower closure B , which, when opened, removes the residues of the Gasification fall down automatically. As far as the retort is in the fire, it is provided on one side with the full height slot 5 ", which is connected to the vertical collecting duct D, which is walled into the furnace wall and thus deprived of direct heating to prevent charging of the retort through the slot J? in the collecting channel D, sharply inclined intermediate walls CC are incorporated in the longitudinal section. the collection channel D is connected in a suitable manner with the Teervorlage, and in its end wall closable openings EE are arranged which a regular Allow cleaning of the slot or the side openings of the retort in the event of any coke sticking by piercing it. The retort R is given a circular, elliptical or other suitable cross section. In the case of smaller versions, it is made up of one piece, and in the case of larger versions, it is made up of several lengths. Several such retorts can be set up in one furnace room and heated together. The vertical slot on the side can be replaced by openings of the retort, one above the other, of any shape and division. What remains characteristic of the process, however, is that the gases can easily escape sideways from as many and therefore low layers of fuel in the retort as possible and collect on the shortest route in a channel removed from the furnace, from which they can then be withdrawn. Ρλτενϊ claim: Process for generating luminous gas and heating gas by dry distillation with evacuation of the gases from the stationary retort through a series of provided throughout the height of the retort Openings in a collecting channel, characterized in that the collecting channel is subject to direct action is withdrawn from the furnace. 1 sheet of drawings.
