PATENTAMTPATENT OFFICE
Die Erfindung betrifft ein Verfahren zur Herbeiführung einer rauchlosen Verbrennung bei Feuerungen durch Einführen flüssigen Brennstoffes.The invention relates to a method for bringing about smokeless combustion in the case of furnaces by introducing liquid fuel.
Nach dem Beschicken oder bei forciertem. Betrieb kommt es oft vor, daß die zuerst gebildete Kohlensäure zu Kohlenoxyd reduziert wird. Diese Gase wieder zu verbrennen, ist aber wegen ihrer hohen Entzündungstemperatur schwierig. Zweck des neuen Verfahrens ist es nun, die Entzündungstemperatur zu erniedrigen. 'Zu diesem Zweck wird in die sauerstoffärmste Zone des Brennstoffes (in die Reduktionszone) flüssiger Brennstoff eingeleitet, und zwar derart, daß er auf seinem Wege mit Luft nicht in Berührung kommt. Die Gase des flüssigen Brennstoffes reichern dann in der saustoffärmsten Zone die dort vorhandenen Gase an und bilden mit ihnen ein Gemisch, dessen Entzündungstemperatur niedriger ist als die Entzündungstemperatur der Verbrennungsgase allein. Es ist dann die Möglichkeit gegeben, daß die Verbrennungsgase in jenem Gemisch bei genügender Luftzufuhr vollständig verbrennen. Es ist zwar bekannt, dem Brennstoff Brenngase zuzuleiten, indem man ein Gemisch von Preßluft und zerstäubtem oder vergastem flüssigen Brennstoff durch die hohlen Roststäbe zuführt. Das Gemisch verbrennt jedoch unmittelbar bei seinem Austritt aus den Roststäben. Dies hat seinen Grund in dem Vorhandensein von Luft in dem Augenblicke, in welchem eine Berührung zwischem dem Gemisch und dem Brennstoff stattfindet. - Eine Erniedrigung der Entzündungstemperatur findet daher nicht statt.After loading or with forced. Operation it often happens that the first formed carbonic acid is reduced to carbon dioxide. To burn these gases again but is difficult because of its high ignition temperature. Purpose of the new procedure it is now to lower the inflammation temperature. 'For this purpose, the fuel is in the oxygen-poorest zone (In the reduction zone) liquid fuel introduced, in such a way that he on does not come into contact with air on his way. Liquid fuel gases The gases present there then accumulate and form in the zone with the least oxygen with them a mixture whose ignition temperature is lower than the ignition temperature the combustion gases alone. There is then the possibility that the combustion gases in that mixture with sufficient Completely burn air supply. It is known that the fuel is fuel gases by passing a mixture of compressed air and atomized or gasified liquid fuel through the hollow grate bars feeds. However, the mixture burns immediately as it emerges from the grate bars. This is because of this Presence of air at the moment there is contact between the Mixture and the fuel takes place. - A decrease in the inflammation temperature therefore does not take place.
Bei der Erfindung kommt es demgegenüber darauf an, daß die unverbrannten Bestandteile der Verbrennungsgase — Kohlenoxyde — mit den Gasen des flüssigen Brennstoffes angereichert werden. Zu diesem 'Zweck erfolgt die. Zuführung des flüssigen Brennstoffes in solcher Weise, daß der Zutritt von Luft so lange ausgeschlossen ist, bis der vergaste flüssige Brennstoff in die sauerstoffärmste Zone der Rostbeschickung gelangt ist.In the invention, however, it is important that the unburned constituents the combustion gases - carbon oxides - with the gases of the liquid fuel be enriched. For this purpose the. Feeding the liquid Fuel in such a way that air is not allowed to enter until the gasified liquid fuel enters the low-oxygen zone of the grate feed has arrived.
Die Ausführung der Erfindung kann in verschiedener Weise erfolgen. Die Brenngase können z. B. auf die Weise zugeführt werden, daß in die sauerstoffärmste Zone Rohrleitungen ausmünden, in welche die Brenngase geleitet werden. Es kann auch ein besonders gebauter Rost zur Anwendung kommen. Naturgemäß wird die Zuführung der Brenngase nur dann erfolgen, wenn die Entwicklung solcher bisher unverbrannt entweichender Gase stattfindet, also insbesondere wenn frischer Brennstoff aufgeschüttet wird.The invention can be carried out in various ways. The fuel gases can e.g. B. be supplied in such a way that in the oxygen-poorest zone Open out pipes into which the fuel gases are directed. It can also a specially built grate can be used. Naturally, the fuel gases will only be supplied if the Development of such previously unburned escaping gases takes place, so in particular when fresh fuel is added.
Zweckmäßig wird dem Brennstoff von unten noch Wasserdampf zugeführt, um die Verbrennungszone des Gemisches möglichst nach oben zu verlegen. Bei der Verwendung von Wasserdampf muß aber darauf geachtet werden, daß die Zuführung in solcher WeiseThe fuel is expediently supplied with water vapor from below in order to reduce the To move the combustion zone of the mixture upwards if possible. When using but care must be taken to ensure that the supply of water vapor is carried out in such a way
erfolgt, daß ein Zusammentritt von Wasserdampf mit den Brenngasen nicht stattfindet.takes place so that a meeting of water vapor with the fuel gases does not take place.
