IMPERIAL PATENT OFFICE. PATENT LETTERING JV * 282355 CLASS 26 «. GROUP ADOLF HECKERT in KOCHEL a. Lake. Method and retort for dry distillation of coal or the like with additive of water vapor. Patented in the German Empire from €. March 1914. Attempts have already been made several times in the dry distillation of coal or the like to influence the formation of the gas by adding water vapor.
Due to the difficulties that horizontal retorts present with the addition of water vapor, in that the steam supply pipes are primarily laid with coal dust and tar, this method has only been encountered so far ίο Found application for vertical retorts. With the present invention these deficiencies and others since then, the Using the addition of steam eliminates opposing obstacles. For this purpose, the water vapor is first superheated in the retort and then decomposed, whereupon the decomposition products of the coal to be gasified are fed. The attached drawing shows a so-called Continuous retort with two heads shown in section. The front, larger part or chamber a is used for charging coal or the like, the rear, smaller part for steam overheating and decomposition. The latter is in turn subdivided into two chambers, of which the chamber b immediately adjoining the part α is larger in size than the chamber c forming the rear closure. The chamber b is separated from the chamber a by a partition d with one or more upper passage openings e, the chamber c from the chamber b by a wall f with one or more lower passage openings g . The wet steam is superheated in Jer chamber c. For this purpose, tongue-like internals h made of refractory bricks are provided, which force the steam to penetrate the chamber c in zigzag windings and to dry and overheat itself by absorbing heat. The chamber b is filled with glowing graphite or other suitable vapor decomposition material. The water vapor introduced through the channel i from below into the chamber b overheats when it passes along the internals h and passes through the openings g of the partition f into the chamber b , so that it is forced to admit as much of the glowing graphite as possible enforce and thereby completely decompose before it can pass through the upper openings β of the partition wall d into the gasification chamber α and act on its contents. Since the graphite is consumed during the decomposition of the superheated water vapor, the chamber b must be refilled or topped up from time to time, whereby a new, beneficial one is created at the same time (2nd edition, issued on ΐη.
