Description

Dampfkesselanlage für Brennstaubfeuerung Die Erfindung bezieht sich auf eine Dampfkesselanlage, die insbesondere mit Brennstaub hefewert wird und die beispielsweise aus einer Anzahl winklig zueinander angeordneter Oberkessel mit ebenso gelagerten Unterkesseln besteht, die durch Wasserrohre miteinander in Verbindung stehen. Es ist auch bekannt, in solcher polygonalen Kesselanlage die Brenner in den Kanten anzubringen, die gegebenenfalls abgeschrägt sein können, und sich die Anlage nach oben zu verjüngen zu lassen, damit die Gasgeschwindigkeit in ihr gleichmäßig bleibt.Steam boiler system for pulverized fuel combustion The invention relates on a steam boiler system, which is yeast value in particular with pulverized fuel and which for example from a number of upper boilers arranged at an angle to one another with the same stored sub-boilers, which are connected to each other by water pipes stand. It is also known to use the burners in such a polygonal boiler system to attach the edges, which may be beveled if necessary, and the Allow the plant to taper upwards so that the gas velocity in it is even remain.

Ferner ist es bekannt, in der Mitte im unteren Teile einer Verbrennungskammer einen Speisewasserkessel anzuordnen, der mit den Untertrommeln durch radiale Wasserrohre in Verbindung steht.It is also known to be in the middle in the lower part of a combustion chamber to arrange a feed water boiler with the lower drums through radial water pipes communicates.

Die Erfindung besteht nun in der Vereinigung der verschiedenen an sich bekannten Merkmale, nämlich den winklig zueinander angeordneten Obertrommeln, dazu parallel liegenden Untertrommeln, beide miteinander verbindenden Rohrbündeln, die einen Feuerraum in Form einer abgestumpften Pyramide umschließen, eines im unteren Teile der Brennkammer zentral angeordneten Speisewasserkessels, der mit den Untertrommeln durch radial verlaufende Rohre verbunden und mit einer feuerfesten, die Flamme zündenden Hülle umgeben ist, und Brennern, die von den Kanten des Feuerraumes aus tangential auf den zentral angeordneten Speisewasserkessel gerichtet sind.The invention now consists in the union of the various well-known features, namely the top drums arranged at an angle to one another, lower drums lying parallel to it, both pipe bundles connecting with each other, which enclose a firebox in the form of a truncated pyramid, one in the lower Parts of the combustion chamber centrally arranged feed water boiler, the one with the lower drums connected by radial pipes and with a refractory that ignites the flame Envelope is surrounded, and burners that are tangential from the edges of the furnace are directed towards the centrally arranged feed water boiler.

Durch diese Vereinigung wird der Vorteil erreicht, daß eine sichere Zündung der Flamme, eine gute Kühlung der ausfallenden Ascheteilchen und eine gleichmäßige Speisewasserversorgung des die Feuerkammer umschließenden Kessels eintritt.This union has the advantage that a safe Ignition of the flame, good cooling of the precipitating ash particles and uniform Feed water supply of the boiler surrounding the firebox enters.

Ein Ausführungsbeispiel der Erfindung ist in den Abb. i und 2 veranschaulicht. Abb. i ist senkrechter Schnitt und Ansicht. Abb. 2 ist Horizontalschnitt nach Linie;-; bzw. 7'-7' der Abb. i.An embodiment of the invention is illustrated in FIGS. Fig. I is a vertical section and elevation. Fig. 2 is a horizontal section along the line; and 7'-7 'of Fig. i.

Die Kesselanlage besteht in der Hauptsache aus mehreren Oberkesseln a und entsprechenden Unterkesseln b, die miteinander durch Wasserrohre d in Verbindung stehen, so daß ein polygonales Gebilde entsteht, dessen Ecken abgeschrägt sind. In diesen Eckwänden e° sind die Brenner e1 angeordnet. Im unteren Teil des Verbrennungsraumes ist etwa in der Mitte ein Speisewasserkessel c angeordnet, der mittels der Wasserrohre (l= mit den Untertrommeln b in Verbindung steht. Diese Rohre d2 bilden einen Wasserrost zur Kühlung der herabfallenden Asche. Der Speisewasserkessel c ist mit einer feuerfesten Schicht cl bekleidet, die durch die tangential auf den Kessel c gerichteten Brenner e1 zum Glühen gebracht wird, so daß sich die Kohlenstaubteilchen an ihm entzünden, falls die Flamme abgerissen sein sollte.The boiler system mainly consists of several upper boilers a and corresponding sub-boilers b, which communicate with each other through water pipes d stand, so that a polygonal structure is created, the corners of which are bevelled. The burners e1 are arranged in these corner walls e °. In the lower part of the combustion chamber a feed water boiler c is arranged approximately in the middle, which by means of the water pipes (l = is connected to the lower drums b. These pipes d2 form a water grate to cool the falling ash. The feed water boiler c is fireproof Layer cl clad the burner directed tangentially to boiler c e1 is made to glow so that the coal dust particles ignite on it, in case the flame is lost.
