Abstract

The invention relates to a gasification boiler for the combustion of solid fuels, in particular bales of straw, for heating purposes and for the production of hot water. The inventive boiler is characterized by optimal combustion and ash separation. The aim of the invention is to carry out the combustion of small particles in the most complete manner possible and to achieve an almost total separation of the ashes from the combustion gas upstream of the heat exchangers. To achieve this, according to the first feature of claim 1, the combustion and gasification chamber comprises lateral depressions that are configured next to the central grating and combustion chamber. Coarse particles collect in said depressions, leaving the fine particles to be carried with the combustion gas into the combustion chamber. According to the second feature of said claim, a cylindrical combustion chamber, configured as an additional component, is connected to the outlet of the combustion chamber. Said secondary combustion chamber significantly increases the combustion time, allowing small particles and partially oxidized gases to burn completely. According to the third feature, a cylindrical ash separator, configured as an additional component, is connected to the combustion chamber.

Stand der TechnikState of the art

Das Prinzip der Brennstoffvergasung in einem Feuerraum und der Nachverbrennung in einem gesonderten Brennraum besitzt für stückige Brennstoffe wesentliche Vorteile. Das sind hauptsächlich eine weitgehende, saubere Verbrennung, damit geringe Umweltbelastung und eine hohe Energieausbeute. Die bekannten Ausführungen bestehen aus einem geschlossenen Brennstofffüllraum mit Fülltür, einer unteren Abbrand- und Vergasungszone, einem unteren Rost und Brenndüse mit einem darunter bzw. dahinterliegendem Brennraum, Luftzuführungen, Wärmetauscher und Ascheabscheider. Ein derartiger Heizkessel für Feststoffverbrennung ist beispielhaft in der DE OS 34 08 602 und DE PS 37 18 022 beschrieben. Zur Verbesserung der Verbrennung sind besondere Luft- und Brenngasführungen vorgeschlagen worden. Entsprechend der DE OS 3411822 hat der Füllschacht die Form eines Doppelkegels mit Gasabströmöffnungen und einen Brennringkanal in der Erweiterung. Damit soll ein gleichmäßiger Abbrand und einfacher Aufbau bewirkt werden.The principle of fuel gasification in a combustion chamber and the post-combustion in a separate combustion chamber has significant advantages for particulate fuels. These are mainly a far-reaching, clean combustion, so low environmental impact and high energy yield. The known designs consist of a closed fuel filling chamber with filling door, a lower combustion and gasification zone, a lower grate and combustion nozzle with an underlying or behind the combustion chamber, air ducts, heat exchangers and ash separator. One Such boiler for solid combustion is exemplary in the DE OS 34 08 602 and DE PS 37 18 022 described. To improve combustion, special air and fuel gas ducts have been proposed. According to the DE OS 3411822 the hopper has the shape of a double cone with Gasabströmöffnungen and a torch channel in the extension. This is intended to bring about a uniform burnup and simple construction.

In der DE PS 3617146 wird eine spezielle Luftzuführung für die Primärluft dargestellt, um eine gute Brenngas-Luftmischung zu erreichen. Das Gebläse ist auf der Fülltür montiert und führt Außenluft in drei Ebenen des Brennstoffschachtes zu. Die Lösung in der DE PS 3718022 enthält zwei Luftzuführungsebenen im Brennstoffschacht und eine zum Brennraum. Mit der Rückführung von Abgas soll eine besonders gute Vergasung erreicht werden.In the DE PS 3617146 A special air supply for the primary air is shown to achieve a good fuel gas-air mixture. The blower is mounted on the filler door and supplies outside air into three levels of the fuel chute. The solution in the DE PS 3718022 contains two air supply levels in the fuel slot and one to the combustion chamber. With the return of exhaust gas a particularly good gasification is to be achieved.

Der Brennstoff Getreidestrohballen bewirkt besondere Anforderungen. Es besteht das Problem einer gleichmäßigen vergasung, die durch Verkohlung der äußeren Schichten behindert wird. Ein hoher Gehalt an unverbrannten Kleinbestandteilen und ein niedriger Ascheschmelzpunkt wirken sich ungünstig auf die Abgaswerte aus und verschmutzen die Wärmetauschflächen ( DE OS 41 34 754 ).The fuel grain straw bale causes special requirements. There is the problem of uniform gasification which is hampered by charring the outer layers. A high content of unburned small components and a low ash melting point have an unfavorable effect on the exhaust gas values and pollute the heat exchange surfaces ( DE OS 41 34 754 ).

[Aufgabe der Erfindung]OBJECT OF THE INVENTION

Aufgabe der Erfindung ist es, die Verbrennung auch von Kleinteilen möglichst vollständig durchzuführen und die Asche annähernd vollständig bereits vor den Wärmetauschern aus dem Brenngas abzutrennen.The object of the invention is to carry out the combustion of small parts as completely as possible and to separate the ash almost completely already before the heat exchangers from the fuel gas.

Gelöst wird diese Aufgabe durch die Merkmale des Anspruchs 1.This problem is solved by the features of claim 1.

Gemäß Merkmal eins besitzt der Brennstoff- und Vergasungsraum seitlich neben dem mittig angeordneten Rost und dem Brennraum Vertiefungen. In diesen sammeln sich grobe Teilchen, während nur noch die Feinteile mit dem Brenngas in den Brennraum mitgeführt werden. Die groben Teile können in den Vertiefungen ausgasen und belasten den Brenngastrom nicht. Nach Abschluss der Verbrennung kann die verbleibende Asche dort entnommen werden.According to feature one, the fuel and gasification chamber has recesses laterally adjacent to the centrally located grate and the combustion chamber. In these coarse particles collect, while only the fines with the fuel gas are carried in the combustion chamber. The coarse parts can outgas in the wells and do not burden the fuel gas flow. After completion of the combustion, the remaining ash can be removed there.

Entsprechend Merkmal zwei ist an dem Ausgang des Brennraumes eine als zusätzliche Baueinheit ausgebildete, zylinderförmige, Brennkammer angeschlossen. Durch diese Nachbrennkammer wird die Verbrennungszeit erheblich verlängert, wodurch enthaltene Kleinteile und teiloxydierte Gase vollständig verbrennen. Die tangentiale Einleitung des Brenngases wirkt wie ein Zyklon, so dass sich am Boden weitere Asche sammelt. Diese kann durch einen Deckel entnommen werden.In accordance with feature two, a cylindrical combustion chamber designed as an additional structural unit is connected to the outlet of the combustion chamber. By this Nachbrennkammer the combustion time is considerably extended, which contained small parts and teiloxydierte gases burn completely. The tangential introduction of the fuel gas acts like a cyclone, so that more ash collects on the ground. This can be removed through a lid.

Nach Merkmal drei ist an der Brennkammer eine als zusätzliche Baueinheit ausgebildeter, zylinderförmiger, Ascheabscheider angeschlossen. In diesem werden die restlichen Aschebestandteile aus dem Rauchgas entfernt. Der nachfolgend angeordnete Wärmetauscher wird somit nicht mehr mit Asche belastet.According to feature three, a cylindrical, ash separator designed as an additional structural unit is connected to the combustion chamber. In this, the remaining ash components are removed from the flue gas. The subsequently arranged heat exchanger is thus no longer burdened with ash.

Das Zusammenwirken der drei baulichen Merkmale bewirkt somit eine vollständigere Verbrennung, verbesserte Ascheabscheidung und damit geringere Abgasbelastung. Zusätzlich werden aber auch die Wartung und Lebensdauer des Wärmetauschers verbessert.The interaction of the three structural features thus causes a more complete combustion, improved ash separation and thus lower exhaust pollution. In addition, however, the maintenance and life of the heat exchanger are improved.

Spezielle Ausgestaltungen der Erfindung sind in den Unteransprüchen dargelegt.Specific embodiments of the invention are set forth in the subclaims.

In einem Gehäuse ist ein Brennstoff- und Vergasungsraum 1 und darunter ein liegender, zylinderförmiger Brennraum 3 angeordnet. Eine Fülltür für den Strohballen und zwei Türen für die Ascheentnahme sind auf der Vorderseite befestigt. Am unteren Scheitel des Brennstoff- und Vergasungsraumes 1 ist ein Längsschlitz im Boden vorhanden, der sich über die ganze Tiefe erstreckt. In diesem ist ein Rost 2 eingelassen. Unterhalb des Rostes 2 befinden sich Gasdüsen, die in einem Brennraum 6 münden. Dieser besteht aus Rohrabschnitten aus Feuerbeton, die in einem Stahlrohr geführt sind.In a housing, a fuel and gasification chamber 1 and below a lying, cylindrical combustion chamber 3 is arranged. A straw bale loading door and two ash removal doors are attached to the front. At the lower apex of the fuel and gasification chamber 1, a longitudinal slot in the ground is present, which extends over the entire depth. In this a 2 grate is taken in. Below the grate 2 are gas nozzles, which open into a combustion chamber 6. This consists of sections of refractory concrete, which are guided in a steel tube.

Der Brennstoff- und Vergasungsraumes 1 besitzt parallel zum Rost 2 und Brennraum 3 Vertiefungen 4. Diese sind halbschalenförmig ausgebildet. Die Wandung besitzt im Endbereich jeweils eine Tür zu Ascheentnahme.The fuel and gasification chamber 1 has parallel to the grate 2 and the combustion chamber 3 recesses 4. These are half-shell-shaped. The wall has in each case a door to ash removal in the end.

Der Heizkessel mit Brennstoff- und Vergasungsraumes 1 und Brennraum 3 ist als ein Baueinheit ausgeführt.The boiler with fuel and gasification chamber 1 and combustion chamber 3 is designed as a structural unit.

Die nachgeordnete Brennkammer 5, Ascheabscheider 6 und Wärmetauscher werden durch ein Gestell 10 zu einer weitere Baueinheit zusammengefasst.The downstream combustion chamber 5, ash separator 6 and heat exchangers are combined by a frame 10 to form another unit.

Brennkammer 5 und Ascheabscheider 6 besitzen ein senkrecht stehendes, zylinderförmiges Gehäuse. Die Wände der Gehäuse sind isoliert, oben sind diese durch einen schalenförmigen Deckel verschlossen.Combustion chamber 5 and ash separator 6 have a vertical, cylindrical housing. The walls of the housing are insulated, the top of which are closed by a cup-shaped lid.

Im Ascheabscheider ist zentrisch im oberen Bereich ein Rohr und unterhalb ein kreisringförmiges Leitblech(8) so angebracht ist, dass zur Außenwandung eine ringförmige Öffnung für den Ascheniederschlag verbleibt.In the ash separator is centrally in the upper part of a pipe and below an annular guide plate (8) is mounted so that the outer wall remains an annular opening for the ash precipitate.

Die sich anschließenden Wärmeaustauscher sind in einem senkrechten Rauchgasabzug angeordnet.The subsequent heat exchangers are arranged in a vertical flue gas outlet.

Die Verbrennungsgase besitzen durch ein Umluftgebläse im Brennstoff- und Vergasungsraumes 1 eine Rotationsbewegung. Die losen, schweren Teilchen des Brenngutes sammeln sich in den äußeren, seitlichen Vertiefungen 4 und brennen dort vollständig aus. Leichte Schwebteilchen werden mit dem Brenngastrom mitgerissen und spätestens in der Brennkammer 5 vollständig verbrannt. Im Ascheabscheider 6 erfolgt eine mehrfache Abtrennung der Asche. Bei der Gaseinströmung werden die Ascheteilchen an die Innenwandung gedrückt und fallen bei der Umlenkung durch das Leitblech 8 nach unten. Die Ascheentnahme erfolgt durch die oberen Deckel 7, 9 und eine Tür im Bodenbereich des Ascheabscheiders 6. Der so gereinigte Gasstrom wird über die Wärmetauscher geleitet.The combustion gases have by a circulating air blower in the fuel and gasification chamber 1 a rotational movement. The loose, heavy particles of the combustible material accumulate in the outer, lateral depressions 4 and burn out completely there. Light suspended particles are entrained with the fuel gas stream and completely burned at the latest in the combustion chamber 5. In the ash separator 6 there is a multiple separation of the ash. When the gas flows in the ash particles are pressed against the inner wall and fall during the deflection by the baffle 8 down. The ash removal takes place through the upper cover 7, 9 and a door in the bottom region of the ash separator 6. The thus purified gas stream is passed through the heat exchanger.
