The sludge container 24 is emptied via a shut-off valve 37 in the bottom area of the sludge tank 34 is arranged.

Der Ablauf der Reinigung der Brennkammer und der Rauchgaszüge wird nachfolgend anhand der in Fig. 1 dargestellten Vorrichtung erläutert. Nachdem das Druckrohr 7 und der Absaugschlauch 8 in die Manschette 9 eingeführt wurden, wird die Manschette 9 in die Flammrohröffnung 4 des Heizkessels 1 eingesetzt und mittels der Handballenpumpe 10 mit Luft beaufschlagt, so daß sie abdichtend an der Innenwandung der Flammrohröffnung 4 sowie an dem Druckrohr 7 und dem Absaugschlauch 8 anliegt. Hiernach befinden sich die Zerstäuberdüse 15 und das freie Ende des Absaugschlauches 8 in der Brennkammer 2, wobei die Blattfeder 36 das freie Ende des Absaugschlauches 8 zum Boden der Brennkammer 2 orientiert. Das andere Ende des Absaugschlauches 8 wird in ein Waschbecken 17 mit einem Abwasser-Kanalanschluß 18 eingehängt und das Druckrohr 7 wird über das geschlossene Ventil 14 mit dem Druckschlauch 12 gekoppelt, der an das Auslaufventil 13 des Leitungswassernetzes angeschlossen ist. Gegebenenfalls kann dem Druckrohr 7 oder dem Druckschlauch 12 ein Druckminderventil zugeordnet werden.The process of cleaning the combustion chamber and the flue gas flues is subsequently based on the device shown in Fig. 1 explained. After the pressure pipe 7 and the suction hose 8 have been inserted into the cuff 9, the Sleeve 9 inserted into the flame tube opening 4 of the boiler 1 and pressurized with air by means of the palm pump 10, so that they seal against the inner wall of the flame tube opening 4 and on the pressure pipe 7 and the suction hose 8 is present. After this are the atomizer nozzle 15 and the free end of the suction hose 8 in the combustion chamber 2, the leaf spring 36 the free end of the suction hose 8 oriented towards the bottom of the combustion chamber 2. The other end of the Suction hose 8 is in a sink 17 with a sewer connection 18 hung and the pressure pipe 7 is coupled to the pressure hose 12 via the closed valve 14, the to the outlet valve 13 of the tap water network connected. If necessary, the pressure pipe 7 or a pressure reducing valve can be assigned to the pressure hose 12.

Anschließend werden das Auslaufventil 13 und das Ventil 14 geöffnet, wonach vernebelte Reinigungsflüssigkeit 11 durch die Zerstäuberdüse 15 in die Brennkammer gelangt. Dort schlägt sich die Reinigungsflüssigkeit 11 auf den Verbrennungsrückständen nieder und löst diese von der Wandung der Brennkammer 2 und den Rauchgaszügen 3. Im Falle einer großen Brennkammer 2, wird das Druckrohr 7 in der Manschette 9 verschoben, so daß die vernebelte Reinigungsflüssigkeit 11 an alle Stellen innerhalb der Brennkammer 2 gelangt.Then the outlet valve 13 and the valve 14 opened, after which atomized cleaning liquid 11 through the atomizer nozzle 15 enters the combustion chamber. There the cleaning liquid 11 strikes on the combustion residues down and detaches it from the wall of the Combustion chamber 2 and the flue gas flues 3. In the case of a large one Combustion chamber 2, the pressure pipe 7 is displaced in the sleeve 9, so that the atomized cleaning liquid 11 all places within the combustion chamber 2.

Nun wird die Saugpumpe 16 eingeschaltet und die gelösten und auf dem Boden der Brennkammer 2 angesammelten Verbrennungsrückstände werden von dem Absaugschlauch 8 aufgenommen und über den Abwasser-Kanalanschluß 18 dem Kanalnetz zugeleitet. Das Eintragen der Reinigungsflüssigkeit und das Absaugen der Verbrennungsrückstände erfolgen solange gleichzeitig, bis die Brennkammer 2 des Heizkessels 1 vollständig von Verbrennungsrückständen befreit ist, wobei der Zufluß der Reinigungsflüssigkeit 11 mit dem Ventil 14 reguliert werden kann. Während dieser Vorgänge kann aufgrund der Reinigungsflüssigkeit 11, die die gelösten Verbrennungsrückstände bindet, und der abgedichteten Anordnung des Druckrohres 7 sowie des Absaugschlauches 8 kein Staub aus der Brennkammer 2 austreten.Now the suction pump 16 is switched on and the dissolved and combustion residues accumulated on the bottom of the combustion chamber 2 are absorbed by the suction hose 8 and fed to the sewer network via the sewer connection 18. Entering the cleaning liquid and vacuuming the Combustion residues occur simultaneously until the Combustion chamber 2 of the boiler 1 completely of combustion residues is freed, the inflow of the cleaning liquid 11 can be regulated with the valve 14. While due to the cleaning liquid 11, which binds the dissolved combustion residues, and the sealed Arrangement of the pressure pipe 7 and the suction hose 8 no dust can escape from the combustion chamber 2.

Zur Beendigung der Reinigung der Brennkammer 2 wird das Auslaufventil 13 geschlossen und über den Absaugschlauch 8 werden die noch in der Brennkammer 2 verbliebenen gelösten Verbrennungsrückstände sowie die restliche Reinigungsflüssigkeit 11 abgesaugt. Anschließend wird die Saugpumpe 16 ausgeschaltet und die Druckluft aus der Manschette 9 entfernt. Nun kann die Manschette 9 mitsamt dem Druckrohr 7 und dem Absaugschlauch 8 der Flammrohröffnung 4 entnommen werden.To finish cleaning the combustion chamber 2, the outlet valve 13 are closed and over the suction hose 8 the dissolved combustion residues still remaining in the combustion chamber 2 as well as the remaining cleaning liquid 11 sucked off. The suction pump 16 is then switched off and the compressed air is removed from the cuff 9. Well now the cuff 9 together with the pressure pipe 7 and the suction hose 8 of the flame tube opening 4 can be removed.
