Description

Pateντ-Anspruch:Pateντ claim:

Ein Verfahren, die bei der Verbrennung von Kohlen auftretende schweflige Säure durch Einblasen zerstäubter Lösungen von Aetzkalk oder anderen Basen in den Verbrennungsraum chemisch zu binden und dadurch unschädlich zu machen, bevor die Flamme den zu erhitzenden Gegenstand berührt, während das gleichzeitig sich bildende Wassergas zur Erhöhung des Hcizeffectes beiträgt.A method of blowing in the sulphurous acid that occurs when coal is burned atomized solutions of caustic lime or other bases in the combustion chamber chemically to bind and thereby render harmless before the flame reaches the one to be heated Object touches while the simultaneously forming water gas to increase the Hcizeffectes contributes.

KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. unschädlich zu machen.to render harmless. Alle Kohlensorten haben mehr oder weniger hohen Schwefelgehalt, wovon bei der Verbrennung ein Theil zu schwefliger Saure verbrennt; diese wirkt zerstörend auf die Kesselbleche und schädlich für Menschen, Thiere und Vegetation. ·All types of coal have more or less high sulfur content, of which when burned a part burns to sulphurous acid; this has a destructive effect on the boiler plates and harmful to humans, animals and vegetation. · Diesem Uebelstande soll die vorliegende Erfindung abhelfen und gleichzeitig soll der Heizwerth der Kohle erhöht werden.The present invention is intended to remedy this inconvenience and at the same time the calorific value the coal will be increased. Zu diesem Zweck werden in dem Verbrennungsraum der Dampfkessel die Vcrbrcnnungsgase mit Kalkwasser oder Kalkmilch oder anderen Basen in Berührung gebracht; diese Basen werden ununterbrochen in dem Verhaltnisse zur Menge der gebildeten schwefligen Säure zugeführt, und zwar in der Weise, dafs die lein zerstreute Absorptionsflüssigkeit sowohl den oxydirenden als auch deii reducirenden Theil der Flamme bestreicht; hierbei bindet sich die schweflige Säure und' entweicht als unschädliche Schwefelverbindung in die Esse, während die überschüssige Wassermenge, weil über die glühenden Kohlen streichend, sich in Wassergas zersetzt und den Effect der Verbrennung steigert. Auch der Umstand, dafs die kleineren Kohlentheile durch die stete Befeuchtung des oberen Theiles der Flamme im Verbrennungsraum zur Verbrennung gezwungen werden, erhöht den Effect der Verbrennung. For this purpose, the combustion gases are used in the combustion chamber of the steam boiler brought into contact with lime water or milk of lime or other bases; these bases become uninterrupted in the ratio to the amount of sulfurous acid formed, in such a way that the slightly dispersed absorption fluid is both oxidizing and reducing Brushed part of the flame; here the sulphurous acid binds and escapes as harmless sulfur compound in the forge, while the excess amount of water because Stroking over the glowing coals, decomposes in water gas and the effect of combustion increases. Also the fact that the smaller parts of the coal are removed by the constant moistening of the upper part of the flame are forced to burn in the combustion chamber, increases the effect of the combustion. / sind Dampfkesselfeuerungen. R ist ein Behälter aus Holz oder Eisen, zweitheilig, mit Deckel versehen, in welchem die Absorptionsflüssigkeit vorbereitet wird. Durch die Rohrleitung η gelangt diese Flüssigkeit entweder unmittelbar, oder durch einen Filterkasten F in einen durch Einströmen von Dampf betriebenen Strahlapparat A, um sodann durch Streudüsen in nebelartiger Form, sowohl den oxydirenden als reducirenden Theil der Flamme bestreichend, auszutreten./ are steam boiler systems. R is a container made of wood or iron, two-part, with a lid, in which the absorption liquid is prepared. This liquid passes through the pipe η either directly, or through a filter box F into a jet apparatus A operated by the inflow of steam , in order then to emerge through scatter nozzles in a mist-like form, covering both the oxidizing and reducing parts of the flame. • Durch diese Vorrichtung ist es möglich, die Ausströmungsflüssigkeit auf jo° C. warm zu erhalten, die event, auch noch bis zur Siedetemperatur gebracht werden kann.• With this device, it is possible to keep the outflow liquid warm to jo ° C., which can also be brought up to the boiling point. Aufser einem Manometer M ist auch ein Reductionsventil angebracht.A reduction valve is also attached to a pressure gauge M. Verstopfungen der Streudüsen werden auf die Art beseitigt, dafs man« absperrt und nur den Dampf durchströmen läfst.Blockages of the nozzles are cleared by shutting off and only lets the steam flow through.
