Description

Automatische Heizungsanlagen mit Biomassebefeuerung (beispielsweise Holzhackschnitzel) verbrennen diese Biomasse günstigstenfalls lufttrocken. Die relative Materialfeuchte der Biomasse bewegt sich dabei zwischen 10 und 30%. Da das Wasser vor dem Verbrennungsprozess erwärmt und verdunstet werden muss, muss hierfür beträchtlich Energie aufgewendet werden.automatic Burn heating systems with biomass firing (eg wood chips) this biomass at best air-dry. The relative moisture content of the biomass is moving between 10 and 30%. Because the water before the combustion process heated and has to be evaporated, considerable energy must be expended become.

Die Abgaswärme hingegen kann auf Grund ihrer zu geringen Temperaturdifferenz zum Heizfluidum (z. B. Wasser) wiederum nicht weiter genutzt werden.The exhaust heat on the other hand, due to its too low temperature difference to Heizfluidum (eg., Water) again not be used.

Die am häufigsten verwendete Austragungsmethode aus dem Brennstoffvorratsbehälter besteht aus einem durch einen Getriebemotor angetriebenen tellerartigen Zylinder auf dem Boden des Behälters. Häufig wird die Austragung durch eine an diesem Zylinder befestigte Feder (Blattfeder) unterstützt. Diese Ausführung ist sehr energieintensiv, da das gesamte sich über der Austragung befindliche Material auf den sich bewegenden Teilen lastet.The most frequently used Austragungsmethode from the fuel storage tank consists of a dish-type cylinder driven by a geared motor on the bottom of the container. Frequently becomes the discharge by a spring attached to this cylinder (leaf spring) supported. This execution is very energy intensive, as the whole is over the discharge Material on the moving parts loads.

Da auf dem Behälterboden der größte Materialdruck vorherrscht, ist an dieser Stelle die Materialfeuchte am größten. An der Oberfläche des Behälterinhaltes trocknet das Material (einige Zentimeter tief), durch die sich darüber befindliche (meist trockene) Luft relativ schnell ab.There on the tank bottom the biggest material pressure prevails, at this point, the moisture content is greatest. At the surface of the container contents Dries the material (a few inches deep), through which it is located (mostly dry) air relatively quickly.

Der im Schutzanspruch 1 angegebenen Erfindung liegt das Problem zu Grunde, einen Behälter mit Austragung zu schaffen, in welchem das Brennmaterial getrocknet und unter dem geringsten Energieaufwand ausgetragen werden kann, dieses Problem wird mit den in Schutzanspruch 1 aufgeführten Merkmalen gelöst.Of the in claim 1 protection invention is based on the problem a container with Discharge to create in which the fuel dried and can be carried out with the least amount of energy, This problem is with the features listed in protection claim 1 solved.

Mit der Erfindung wird erreicht, dass das Brennmaterial im Behälter mit Hilfe der Abgaswärme getrocknet wird und das an der Oberfläche abgetrocknete Material kontinuierlich der Verbrennung zugeführt werden kann. Eine Erhöhung des Wirkungsgrades der Heizungsanlage um bis zu 25 Prozent ist dadurch möglich.With The invention is achieved in that the fuel in the container with Help the exhaust heat dried and that will be on the surface dried material can be continuously fed to the combustion can. An increase the efficiency of the heating system by up to 25 percent is thereby possible.

Ein Ausführungsbeispiel der Erfindung wird anhand der 1 bis 5 erläutert. Es zeigen:An embodiment of the invention will be described with reference to 1 to 5 explained. Show it:

1: Den gesamten mit Biomasse (1) befüllten Behälter mit Austragung (4) und Luftführung (3) 1 : The whole with biomass ( 1 ) filled container with discharge ( 4 ) and air ducting ( 3 )

2: Den Behälter mit Lüftungsschlitzen (9), Materialausgang (2) und Austragung (4) ohne Luftführung (3) 2 : The container with vents ( 9 ), Material outlet ( 2 ) and discharge ( 4 ) without air flow ( 3 )

3: Den Behälter mit Austragung (4) ohne Luftführung (3) und ohne Biomasse (1) 3 : The container with discharge ( 4 ) without air flow ( 3 ) and without biomass ( 1 )

4: Die Austragung mit Getriebemotor (4), Wischerarm (5) und Wischer (6) 4 : The discharge with geared motor ( 4 ), Wiper arm ( 5 ) and wipers ( 6 )

5: Die Luftführung (3) 5 : The air duct ( 3 )

In den Figuren ist der Behälter mit der Oberflächen-Austragung und der Trocknungsluftzufuhr abgebildet.In the figures is the container with the surface discharge and the drying air supply shown.

Die aus den Abgasen gewonnene Warmluft (über Wärmetauscher oder direkt) wird vom Ofen zum Behälter (10) geführt und gelangt dort über die Luftführung (3) durch Lüftungsschlitze (9) an die Oberfläche des Behälterinhalts (1).The hot air recovered from the flue gases (via heat exchangers or directly) is transferred from the furnace to the tank ( 10 ) and passes there via the air duct ( 3 ) through ventilation slots ( 9 ) to the surface of the container contents ( 1 ).

Im Behälter befindet sich ein Materialausgang (2), durch welchen das getrocknete Material auf die Materialtransporteinrichtung zum Ofen fällt. Unmittelbar an diesem Ausgang befindet sich das Rührwerk (8), welches mittels verschiedener aus dem Zentrum ragender Körper (zum Beispiel Stäbe) oder Flächen (auch schneckenartig) den Schüttkanal (7) freihalten und der Öffnung kontinuierlich neues Material zuführen. Oberhalb des Rührwerkes befinden sich ein oder mehrere Wischerarme (5). Diese Wischer werden vom Wischerarm über die Oberfläche des Behälterinhaltes bewegt. Dadurch wird das an der Oberfläche befindliche trockene Material abgezogen und dem Schüttkanal zugeführt. Durch die Rotationsbewegung wird das Ende des Wischers stets ins Zentrum des Rührwerkes gezogen.The container contains a material outlet ( 2 ), through which the dried material falls onto the material transport device to the furnace. Immediately at this exit is the agitator ( 8th ), which by means of various protruding from the center body (for example, rods) or surfaces (also snail-like) the bulk channel ( 7 ) and continuously feed the opening with new material. Above the agitator are one or more wiper arms ( 5 ). These wipers are moved by the wiper arm over the surface of the container contents. As a result, the dry material located on the surface is removed and fed to the bulk channel. Due to the rotational movement, the end of the wiper is always pulled into the center of the agitator.

Der Behälter kann aus Stoff bestehen, um die Trocknung zu beschleunigen. An den Wischerarmen (5) können mehrere Wischer (6) gleicher oder verschiedener Länge gleichen oder verschiedenen Materials befestigt sein.The container may be made of fabric to accelerate drying. At the wiper arms ( 5 ), several wipers ( 6 ) are fastened with the same or different length of the same or different material.
