Abstract
Description
Die Erfindung betrifft ein Verfahren zur KohlenstaubverbrennungThe invention relates to a method for burning coal dust
in Großfeuerungsanlagen.in large combustion plants.
Es ist bekannt und üblich und in wachsendem Maße aus volkswirtschaftlichen Gründen wünschenswert, in Grofeuerungsanlagen vermahlenen Kohlestaub zu verfeuern. Die hierauf eingestellten und darauf ausgeriehteten Großfeuerungsanlagen lassen sich den feingemahlenen Kohle staub in Inert-Tankern anliefern und lagern den Kohlestaub in Inert-Silos. Eine Großfeuerungsanlage, die sich von Heizöl auf Kohlestaubfeuerung umstellen will, bedarf des kompletten Umbaus der Brenneranlage. Gleichzeitig müssen bei einer derartigen Umstellung auch die Entstaubungsanlagen umgebaut werden.It is known and common and increasingly from economic Reasons desirable to burn pulverized coal in large combustion plants. Leave the large combustion systems set up and geared to it deliver the finely ground coal dust in inert tankers and store the coal dust in inert silos. A large combustion system that changes from fuel oil to pulverized coal combustion wants to convert requires a complete conversion of the burner system. Must have at the same time In the case of such a conversion, the dust extraction systems are also converted.
Die Umstellung einer Großfeuerungsanlage von Heizöl auf Kohlenstaub erfordert somit bedeutende bauliche Maßnahmen und Änderung des Transport- und Lagersystems.The conversion of a large combustion system from heating oil to coal dust therefore requires significant structural measures and changes to the transport and storage system.
Der Erfindung liegt die Aufgabe zugrunde, diesen Nachteil zu beseitigen und die Umstellung und Einrichtung von Großfeuerungsanlagen zu ermöglichen, die bedeutende Mengen von Kohlenstaub verbrennen.The invention is based on the object of eliminating this disadvantage and enabling the conversion and installation of large-scale combustion plants that produce significant amounts of coal dust burn.
Gelöst wird diese Aufgabe bei einem Verfahren der eingangs erwähnten Art nach der Erfindung dadurch, daß aufgehaldete'oder frisch angelieferte Stückkohle (mit normaler Anlieferfeuchte von ca. 6 - 15 % ) in der Großfeuerungsanlage dosiert und zu Feinstkohle (von etwa 0,09 - 0,2 mm) verrnahlen, die dosierte Feinstkohlenmenge einer ebenfalls dosierten Heizölmenge kontinuierlich zugemischt und die in ihrem Iischungsverhältnis definierte Feinstkohle-Heizöl-Emulsion dem Brenner unmittelbar oder über einen Lagertank zugeführt wird.This object is achieved in a method of the type mentioned at the beginning Type according to the invention in that stocked or freshly delivered lump coal (with normal delivery humidity of approx. 6 - 15%) dosed in the large combustion system and grind to fine carbon (from approx. 0.09 - 0.2 mm), the dosed amount of fine carbon continuously added to a metered amount of heating oil and the in their Mixing ratio defined fine coal-heating oil emulsion directly to the burner or supplied via a storage tank.
Vorteilhaft wird das Mischungsverhältnis der Feinstkohle-Heizöl-Emulsion in Abhängigkeit vom Heizwert der Kohle festgesetzt und reicht bis zu einem Feststoffanteil von ca. 60 %.The mixing ratio of the fine coal / heating oil emulsion is advantageous determined depending on the calorific value of the coal and ranges up to a solid content of about 60%.
Diesem Vorschlag zufolge wird also auf eine totale Umstellung von Heizöl auf Kohlenstaubfeuerung in einer Großfeuerungsanlage verzichtet. Diese nur teilweise Umwandlung von einem Typ einer Großfeuerungsanlage in einen anderen führt zu einem Mischtyp, der unerwartete Vorteile bringt.According to this proposal, a total changeover from Fuel oil dispensed with pulverized coal combustion in a large combustion system. This only partial conversion from one type of large combustion plant to another to a mixed type that brings unexpected benefits.
Die Stückkohlen können in normalen Transportmitteln (Wagon, Schiff und LKW) zur Feuerungsanlage geliefert und beliebig aufgehaldet werden. Der Einsatz von speziellen Inert-Tankern und Inert-Silos entfällt. Da die Stückkohle mit der normalen Anlieferfeuchte herantransportiert und vermahlen wird, entstehen keine solch großen Staubprobleme wie bei besonders trockener Stückkohle. Etwaige Kohlenstaubprobleme werden aber insbesondere dadurch beseitigt, daß eine dosierte Heizölmenge kontinuierlich zugemischt wird, ehe diese Emulsion dem Brenner zugeführt und dort verbrannt wird.The lump coal can be transported in normal means of transport (wagon, ship and trucks) can be delivered to the furnace and heaped up as required. The use There is no need for special inert tankers and inert silos. Since the lump coal with the normal delivery moisture is transported and ground, there are no such large dust problems as with particularly dry lump coal. Any coal dust problems but are in particular eliminated by the fact that a metered amount of heating oil is continuous is admixed before this emulsion is fed to the burner and burned there.
Die Emulsion ist ausreichend lagerfähig und stabil. Sie kann jederzeit in den für die Verfeuerung von Heizöl von Heizöl bestimmten Brennern verbrannt werden, die nur hinsichtlich der Brennerdüsen geringfügige Änderungen erfahren müssen.The emulsion is sufficiently storable and stable. She can anytime are burned in the burners intended for the combustion of heating oil from heating oil, which only have to undergo minor changes with regard to the burner nozzles.
Das oben beschriebene Verfahren ist geeignet, ca. 33 % Heizöl durch Kohle zu ersetzen, ohne daß wesentliche Umstellungsmaßnahmen erforderlich sind. Die bislang beobachtete zögernde Umstellung von Großfeuerungsanlagen von Öl auf Kohle staub kann somit wesentlich beschleunigt werden.The method described above is suitable for approx. 33% heating oil through Replace coal without the need for major conversion measures. The hesitant conversion of large combustion plants from oil to Coal dust can thus be accelerated considerably.
