Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Den Gegenstand vorliegender Erfindung bildet eine Neuerung an Dampfkesseln, welche ein selbsttätiges Entfernen der Flugasche aus den Siederöhren bezweckt.The subject of the present invention forms an innovation in steam boilers, which a the purpose of automatic removal of the fly ash from the boiler tubes.

Fig. ι zeigt den Längsschnitt, Fig. 2 den Querschnitt eines mit der neuen Vorrichtung ausgestatteten Dampfkessels.Fig. Ι shows the longitudinal section, Fig. 2 the Cross-section of a steam boiler equipped with the new device.

In dem Sie'derohr, welches beim Äusführungsbeispiel Galloway-Rohre b aufweist, ist ein waagrechtes Rohr c derart angeordnet, dafs es einestheils die unteren Durchsichtsöffnungen durchsetzt, anderentheils unterhalb des Rostes d hinläuft. Der hinter der Feuerbrücke e gelegene Theil dieses Rohres ist mit feinen Bohrungen/ ausgerüstet. Am hinteren Ende ist dieses Rohr geschlossen, am vorderen Ende ist in dasselbe beispielsweise eine Drosselklappe g eingesetzt, um dieses Ende des Rohres mehr oder weniger weit schliefsen zu können. Durch die den vorderen Theil des Rohres c umgebende heifse Asche wird die durch den Zug des Schornsteins in dasselbe von aufsen hineingesaugte Luft derart erhitzt, dafs sie aus den Oeffhungen in Strahlenform herausgetrieben wird. Diese Strahlen erhalten die Flugasche in wirbelnder Bewegung, durch welche sie allmählich zum Aschenfang h befördert wird. Diese Wirkung kann noch dadurch verstärkt werden, dafs man an das Rohr c das Druckrohr eines Gebläses anschliefst.In the sieve tube, which in the exemplary embodiment has Galloway tubes b , a horizontal tube c is arranged in such a way that it on the one hand passes through the lower viewing openings and on the other runs below the grate d . The part of this pipe behind the fire bridge e is equipped with fine bores /. At the rear end this tube is closed, at the front end, for example, a throttle valve g is inserted into it in order to be able to close this end of the tube to a greater or lesser extent. The hot ash surrounding the front part of the pipe c heats the air drawn in from the outside by the draft of the chimney in such a way that it is driven out of the openings in the form of rays. These jets keep the fly ash in a whirling motion, by means of which it is gradually transported to the ash catcher h . This effect can be intensified by connecting the pressure pipe of a blower to pipe c.
