Abstract
Description
Der Kessel "rondo" besteht wie auch der Brenner "rondell" im Wesentlichen aus zylindrischen Bauteilen, welche koaxial angeordnet sind. Dadurch lassen sich Einlass- und Auslassöffnungen, sowie Reinigungsvorgänge von einer oder mehrerer zentralen, koaxialen Antriebs- oder Steuerwellen (M), bedienen.The boiler "rondo" as well as the burner "rondell" essentially of cylindrical components, which are arranged coaxially. This allows inlet and outlet openings, as well as cleaning operations of one or more central, coaxial drive or control shafts (M) to operate.
Antriebs- bzw. Steuerwelle (M), Brenner "rondell" (W), Abstreifleiste (Y3), innerer Kesselzylinder (S), äußerer Kesselzylinder (T), dazwischen das beheizte Wasser (U) und das Tauscherrohr (TR).Drive or control shaft (M) , torch "rondell" (W) , wiper blade (Y3) , inner boiler cylinder (S) , outer boiler cylinder (T) , between them the heated water (U) and the exchanger tube (TR) .
Auffangraum für die Verbrennungsrückstände (V), Kesselbodenplatte mit einem oder mehrerer Bodenschlitze (Y2), eine oder mehrere Räumleisten (Y1). Der Brenner (W), welcher oben zum inneren Kesselzylinder abschließt und einer nicht dargestellten oberen Abdeckung über der oberen Abgassammelkammer die mit dem äußeren Kesselzylinder (T), abschließt.Containment space for incineration residues ( V) , boiler bottom plate with one or more bottom slots ( Y2) , one or more scrapers ( Y1 ). The burner (W) , which closes at the top to the inner boiler cylinder and a non-illustrated upper cover over the upper exhaust gas collecting chamber with the outer boiler cylinder (T) , closes.
Aus Gründen der Übersicht sind sämtliche Details, wie sonstige Aggregate, Isolierungen, Verkleidungen etc. nicht dargestellt, da diese nicht zum Verständnis der Einzelheiten beitragen. Diese Zusatzausrüstungen sind Stand der Technik und tauchen deshalb hier nicht auf.For the sake of clarity, all the details, such as other aggregates, insulations, Disguises etc. not shown, as these are not for the understanding of the details contribute. These additional equipment are state of the art and therefore do not dive here on.
Der Festbrennstoff (z.B. Pellets) wird wie unter 1. und 2. im Brenner "rondell" verbrannt und gelangt als Abgasstrom in den inneren Kesselzylinder, welcher als Zyklon-Staubabscheider arbeitet. Der im Abgasstrom "mitfliegende" Staubanteil rieselt so zum Kesselboden.The solid fuel (for example pellets) is burned "rondell" in the burner as in 1. and 2. and enters as exhaust gas flow in the inner boiler cylinder, which as a cyclone dust collector is working. The "dusty" dust component in the exhaust gas stream trickles down to the bottom of the boiler.
Über (X1) gelangt der Abgasstrom in ein nur aus einem Abgasrohr bestehenden Nachwärmetauscherrohr (TR), welches aus senkrechten Rohren im Kesselwasser verlaufend besteht. Es entsteht dadurch, dass die einzelnen senkrechten Rohre oben und unten durch Bögen zu einem Rohrverlauf verbunden sind.Via (X1) , the exhaust gas flow reaches a residual heat exchanger pipe (TR) consisting of only one exhaust pipe and consisting of vertical pipes in the boiler water. It arises from the fact that the individual vertical pipes are connected at the top and bottom by arches to a pipe course.
Dadurch erhält das Abgas hohe Strömungsgeschwindigkeit, was den Wärmeübergang durch turbulente Strömung erhöht. Desweiteren sind dadurch Schmutzablagerungen weitgehenst ausgeschlossen. Zur Reinigung sind trotzdem die oberen und unteren Verbindungsbögen aufgesteckt. Nach Entfernen dieser Bögen können die senkrechten Rohre gereinigt werden.This gives the exhaust gas high flow velocity, which the heat transfer through increased turbulent flow. Furthermore dirt deposits are weitgehenst locked out. For cleaning, however, the upper and lower connecting bows attached. After removing these bends, the vertical tubes can be cleaned.
Bis zum unteren Abgaseintritt (X1) wie Fig.01, jedoch besteht hier der Nachtauscher von (X1) bis (XA) aus einer schraubförmigen Abgasrohrschlange. (Fig.02)Up to the lower exhaust gas inlet (X1) as in Fig.01, but here consists of the night exchanger from (X1) to (XA) of a screw-shaped exhaust pipe coil. (Fig.02)
Auf dem Boden des Kesselzylinders befindet sich eine oder mehrere drehbare "Räumleisten" (Y1), welche sich im Ruhezustand, d.h. während des Verbrennungsvorganges, über der oder den Bodenschlitzen (Y2) befinden. Die "Räumleiste(n)" (Y1) werden vor Brennerstarts in Pfeilrichtung (G) gedreht (ähnlich wie auch unter 3.6. Beschrieben), dadurch werden die Verbrennungsrückstände so vom Boden abgestreift und gleiten in Umfangsrichtung auf den oder die Bodenschlitze (Y2) zu, bis sie letztendlich herausfallen und im Auffangraum (V) landen.On the bottom of the boiler cylinder is one or more rotatable "scraper bars" (Y1) , which are at rest, ie during the combustion process, above the floor slit (s) (Y2) . The "scraper (s)" (Y1) are rotated in the direction of arrow (G) before burner starts (similar to 3.6 described above), thus the combustion residues are stripped from the ground and glide in the circumferential direction of the bottom slots or ( Y2 ) until they finally fall out and land in the collection room (V) .
Die Reingung der inneren Kesselzylinderfläche (S) übernimmt die Abstreifleiste (Y3). Besonderheit ist, dass durch die koaxiale Bauweise der Antrieb zentral von einer oder mehrerer Antriebswelle(n) (M) kreisförmig erfolgt. The cleaning of the inner boiler cylinder surface ( S ) takes over the wiper strip ( Y3 ). A special feature is that the coaxial design of the drive centrally of one or more drive shaft (s) ( M ) is circular.
Bei dem Prototyp wird dazu die Antriebswelle (M) des Brenners bis unten verlängert.In the prototype, the drive shaft ( M ) of the burner is extended to the bottom.
Die Antiebsvariante ist, wie unter 2.6. und 3.6. erwähnt, unerheblich, da unterschiedliche Antriebsvarianten möglich und Stand der Technik sind (Getriebemotor, Ketten- oder Zahnradantrieb).The Antiebsvariante is, as under 2.6. and 3.6. mentioned, irrelevant, because different Drive variants are possible and state of the art (gear motor, chain or Gear drive).
Der Brenner besteht wesentlich aus dem "Diskus"-Rost (Boden B), Brennerzylinder (D),
teilbaren Deckel (O) und Antriebswelle (M). Das Material ist feuerbeständig aus Stahl,
mineralisch oder metallisch und mineralisch gemischt.
Zur Ergänzung wird erwähnt, dass bei dem Prototypbrenner (Fig.07) eine Brennerdüse (N) angeformt wurde, damit der Brenner an den Brennerflansch des Versuchskessels angebaut werden kann. Zwischen dem "Diskus"-Rost (B) und dem Boden der Brennerdüse (N) bleibt ein Schlitz (SL), durch welchen die Verbrennungsreste (H) nach unten in eine Auffwangwanne des Brennergehäuses fallen.
To complement it is mentioned that in the prototype burner (Fig.07) a burner nozzle ( N ) was formed so that the burner can be attached to the burner flange of the test boiler. Between the "discus" rust ( B ) and the bottom of the burner nozzle ( N ) remains a slot ( SL ), through which the combustion residues ( H ) fall down into a Auffwangwanne the burner housing.
Der Brenner besteht ebenfalls aus Brennerzylinder, jedoch mit angeformten "Diskus"-Rost
(Zylinder + Boden = P), dem teilbaren Deckel (O) und Antriebswelle (M). Materialien
feuerfest, entsprechend Variante A, was selbstverständlich und Stand der Technik ist.
Abweichend zu Variante A ist die hier die umlaufende "Reinigungs Drehleiste" (Q).
Bei dem Prototyp wird dazu die Antriebswelle (M), an deren unterem Ende die "Räumleiste" (Q) befestigt ist, über einen Kettenantrieb getrieben. Die Antiebsvariante (Stand der Technik) ist auch hier unerheblich, da auch andere Antriebsvarianten möglich sind. Nach dem Reinigungsvorgang verschließt die Räumleiste im Ruhezstand den Bodenschlitz.
In the prototype to the drive shaft (M) , at the lower end of the "scraper blade" (Q) is attached, driven by a chain drive. The Antiebsvariante (prior art) is irrelevant here, as well as other drive variants are possible. After the cleaning process, the scraper closes the Bodenschlitz in Ruhezstand.
