Description

Verfahren zum Verschwelen von stückigen oder mulmigen Brennstoffen. Es hat sich bei der Verschwelung feuchter, stückiger Brennistoffe gezeigt, daß neben dem Anfallen von Teer und Koksrückstand nicht unbedeutende Mengen von zerkrackten Produkten rins Schwelgas Übergehen. Mischt man also bei der Versch#velung mit inerten Gasen diese mit dem Sch-,velgas, so entsteht ein Gas, das wohl aues dem Schwelgas brennbare Bestandteile enthält, jedoch nicht in solchem Umfang' (daß dieses Gas zum Brennen Verwendung finden kann, #so daß seine Verwendung unwirtschaftlich wird. und man esdaher ab-blasen läßt. Um aber auch diese Wärmemengen noch wirtschaftlich ausnutzen zu können, istesnot-#ven,dig"das Gas auf irgendeine Weise anzureichern. Dies geschieht nach der Erfindung in der Weise, daß man an Stelle der inierten Helzgase die heißen Verbrennungsgase der reduzierend geführte#n Staubfeuerung nach dem Hauptpatent458 879 vier-,vendet, so daß also das zur Verschwelung dienende Gas schon einen nennenswerten Betrag von Wärmeeinheiten enthält. Um diese heißen Gase auf die zur Verschwelung erforderliche Temperatur abzukühlen, werden sie mit den entteerten kalten Gasen gemischt. So erhält man neben einem hochwertigen Halbkoks und einem hochivertigen paraffi-I nösen Urteer ein Gesamtgas, das für Verbrennungszwecke geeignet ist. Das Verfahren kann man z.B. vorteilhaft dann anwenden, wenn es sich darum handelt, bei feuchten Rohkohlen die Transportkosten für das Kohlenwasser zu sparen und fdafür einen hochwertigen Halbkoks zum Versand zu bringen. Dann verschwelt man die feuchte Kohle nach dem beschriebenen Verfahren auf der Grube selbst mit Hilfe der Ab#gase einer reduzierend geführten Staubfeuerung, die dem Schwelofen, wie in dem Hauptpatent beschrieben und dargestellt ist, unmittelbar angegliedert ist.Process for smoldering lumpy or queasy fuels. It has been shown in the smoldering of moist, lumpy fuel that, in addition to the accumulation of tar and coke residue, not insignificant amounts of cracked products pass into carbonization gas. So if one mixes these with the smoldering gas during the smoldering with inert gases, a gas is produced which contains flammable constituents outside the smoldering gas, but not to such an extent (that this gas can be used for burning, # so that its use becomes uneconomical. and it is therefore allowed to blow off. But in order to still be able to utilize these amounts of heat economically, it is necessary to enrich the gas in some way. This is done according to the invention in such a way that the hot combustion gases of the reducing dust furnace according to the main patent 458 879 are used in place of the inert gases, so that the gas used for carbonization already contains a significant amount of heat units to cool, they are mixed with the de-tarred cold gases, resulting in a high-quality semi-coke and a high-quality paraffin-like tar egg n total gas suitable for combustion purposes. The method can be used advantageously, for example, when it is a question of saving the transport costs for the hydrocarbons in the case of moist raw coals and for shipping a high-quality semi-coke. Then the moist coal is carbonized according to the method described on the pit itself with the help of the exhaust gases from a reducing dust furnace, which is directly attached to the smoldering furnace, as described and shown in the main patent.
