1878.1878. J. P. PARRAU in DRESDEN. Dampfkesselfeuerung mit zwei übereinander liegenden Rosten.J. P. PARRAU in DRESDEN. Steam boiler with two grids lying on top of each other. Patentirt im Deutschen Reiche vom 18. Januar 1878 ab.Patented in the German Empire on January 18, 1878. Es ist eine bekannte Thatsache, dafs bei der normalen Dampfkesselfeuerimg mit Planrost gewöhnlich nur circa 50 ρ Ct. des in dem Brennmaterial enthaltenen Kohlenstoffs zur vollständigen Oxydation zu Kohlensäure gelangt; der übrige Theil desselben wird entweder nur zu Kohlenoxydgas oxydirt, wodurch eine bedeutend geringere Wärmemenge erzeugt wird, oder er wird vollständig unverbrannt mit fortgerissen. Die neue Dampfkesselfeuerung ist auf Grund von Versuchen construirt, welche mit einer Ofenconstruction mit mehreren übereinanderliegenden Rosten vorgenommen wurden. Es hatte sich durch chemische Analyse der Verbrennungsgase ergeben, dafs bei diesen Versuchen 95 pCt. des vorhandenen Kohlenstoffs zur vollständigen Verbrennung gelangt war.It is a well-known fact that it is common in normal steam boiler firing with a plane grate only about 50 ρ ct. of the carbon contained in the fuel to the full Oxidation leads to carbonic acid; the rest of it either only becomes Carbon oxide gas oxidizes, whereby a considerably smaller amount of heat is produced, or he is carried away completely unburned. The new steam boiler is due of experiments constructed with a furnace construction with several superimposed Rusting were made. It had been found through chemical analysis of the combustion gases show that in these experiments 95 pCt. of the available carbon for complete combustion had arrived. Die vorliegende Construction ist zunächst für einen Locomobilkessel durchgeführt, läfst sich aber leicht für Kessel mit äufserer Feuerung modificiren. Dieselbe besteht aus einem unteren gewöhnlichen Planrost und einem oberen Rost, auf welchem Koks verbrannt werden, wodurch die möglichst vollständige Verbrennung bewirkt werden soll.The construction at hand is initially carried out for a Locomobil boiler but easy to modify for boilers with external firing. The same consists of a lower one ordinary plan grate and an upper grate on which coke is burned, whereby the most complete possible combustion is to be achieved. Der obere Rost macht nun eine besondere Construction nothwendig, damit eine Verbrennung desselben verhindert wird. Derselbe ist deshalb aus Röhren von einem kupferreichen Messingblech construirt, welche behufs lebhafter Circulation des Wassers in denselben eine geneigte Lage haben. Für den Fall, dafs diese Röhren eine zu grofse Abkühlung der Feuergase des unteren Rostes und infolge dessen zu wenig lebhafte Verbrennung verursachen sollten, ist eine Bekleidung aus zwei halben Chamotteröhren in Aussicht genommen. Im anderen Falle würde nur die obere Seite der Röhren mit einer halben, aufsen vierkantigen Schmiedeisenröhre verkleidet, was durch anzustellende Versuche entschieden wird.The upper grate now necessitates a special construction so that it can be burned the same is prevented. It is therefore made of tubes from a copper-rich one Brass sheet is constructed, which for the vigorous circulation of the water in it is inclined Have location. In the event that these tubes have too great a cooling of the fire gases of the lower grate and should not cause vigorous combustion as a result a clothing made of two half chamotte tubes is envisaged. Otherwise it would only the upper side of the tubes is covered with half a square wrought iron tube, what is decided by attempts to be made. Die dampfdichte Verbindung der Röhren in der Feuerkistenwand wird an dem vorderen Ende durch eine Messingmutter, welche innen mit der Röhre und aufsen mit der Wand verschraubt ist und an dem hinteren Ende durch einen etwas konischen Ring bewerkstelligt. Diese Verbindungen sollen durch Chamotte vor der Einwirkung der Flammen geschützt werden.The vapor-tight connection of the tubes in the fire box wall is at the front end by a brass nut, which is screwed inside with the tube and outside with the wall and done at the rear end by a somewhat conical ring. These connections should be protected from the effects of flames by chamotte. Zum Einbringen und Reinigen der Röhren sind in der hinteren Wand Messingpfropfen eingeschraubt. Brass plugs are screwed into the rear wall for inserting and cleaning the tubes.
