Description
Die Erfindung betrifft ein Verfahren zur Aufbereitung und schadstoffarmen Verbrennung fossiler Festbrennstoffe, die ei nem Mahlvorgang zu einer Korngröße von < 3 mm unterworfen wer den, denen wenigstens ein basisches Additiv zur Schadstoffbin dung hinzugefügt wird und die einer Verbrennung bei einer Feuerbettemperatur von weniger als 1300°C unterworfen werden.The invention relates to a method for processing and Low-emission combustion of solid fossil fuels, the egg who are subjected to a grinding process to a grain size of <3 mm to those who have at least one basic additive to bind harmful substances is added and that of a combustion at a Fire bed temperature of less than 1300 ° C to be subjected.
Fossile Brennstoffe werden regelmäßig vor der Verbrennung zer kleinert und getrocknet. Sofern sie nicht mit der geeigneten Mahlfeinheit für die Staubfeuerung eingesetzt werden, findet nach dem Zerkleinern und Trocknen eine Verpressung des Fest brennstoffes zu Briketts oder Pellets mit hohem Druck statt. Die Verpressung des Festbrennstoffes führt zu erheblichen Vor teilen bei der Handhabung der Festbrennstoffe während des Transportes und der Lagerung.Fossil fuels are regularly broken down before combustion crushed and dried. Unless they are with the appropriate one Grinding fineness can be used for dust firing after crushing and drying, pressing the hard fuel to briquettes or pellets with high pressure instead. The compression of the solid fuel leads to considerable advance share in the handling of solid fuels during the Transportes and storage.
Das Emissionsverhalten der in dem Brennstoff enthaltenen Ver unreinigungen, wie insbesondere Schwefel, Chlor, Fluor und Schwermetalle, wird durch die Verpressung nur unwesentlich be einflußt, so daß es bei der Verbrennung zu hohen Schadstoff emissionen, beispielsweise von SO2, HCl und HF, kommt. The emission behavior of the impurities contained in the fuel, such as especially sulfur, chlorine, fluorine and heavy metals, is only slightly influenced by the pressing, so that there are high pollutant emissions during combustion, for example from SO 2 , HCl and HF .
Es ist beispielsweise durch die DE 34 40 593 A1 bekannt, Fest brennstoffe, denen Abfallstoffe zugesetzt werden, basische Ad ditive hinzuzufügen, um eine Einbindung der säurebildenden Schadstoffe zu bewirken. Dabei ist es ferner bekannt, daß die Feuerbettemperatur nicht zu hoch sein darf, um die Schad stoffbindung bei dem anschließenden Verbrennungsvorgang nicht wieder aufzuheben. Bekannt ist daher, die Feuerbettemperatur kleiner als 1300°C einzustellen, wobei die Feuerbettemperatur vorzugsweise zwischen 800 und 1000°C liegt.It is known for example from DE 34 40 593 A1, fixed fuels to which waste materials are added, basic ad add additives to incorporate the acid-forming To cause pollutants. It is also known that the Fire bed temperature must not be too high to damage the No bond in the subsequent combustion process pick up again. The fire bed temperature is therefore known less than 1300 ° C, the fire bed temperature is preferably between 800 and 1000 ° C.
Durch die DE 37 17 191 C1 ist ein Verfahren bekannt, das zur schadstoffarmen Verbrennung von Müll eine Zugabe eines basischen Additivs zu dem mit einer vorgegebenen Feuchtigkeit von 15 bis 35 Gewichtsprozent eingestellten Müll vorsieht. In einem Reaktionsraum verbleibt der Müll wenigstens 10 min und wird anschließend mit einer Feuerbettemperatur von unter 850°C verbrannt. Dieses Verfahren ist nicht für die Verbren nung gemahlener Festbrennstoffe, insbesondere solche in ver preßter Form, vorgesehen.From DE 37 17 191 C1 a method is known which for low-pollution combustion of garbage an addition of a basic additive to that with a given moisture from 15 to 35 percent by weight of garbage. In The waste remains in a reaction space for at least 10 minutes and is then with a fire bed temperature of below Burned at 850 ° C. This procedure is not for cremation ground solid fuels, especially those in ver pressed form, provided.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren der eingangs erwähnten Art anzugeben, das eine schadstoffarme Ver brennung fossiler, feingemahlener Festbrennstoffe ermöglicht.The invention has for its object a method of Specify the type mentioned that a low-pollutant Ver burning fossil, finely ground solid fuels.
Diese Aufgabe wird erfindungsgemäß durch ein Verfahren der eingangs erwähnten Art gelöst, bei dem der gemahlene Fest brennstoff mit dem zugegebenen basischen Additiv für eine Dau er von 10 bis 180 min in einem im wesentlichen geschlossenen Reaktionsraum gehalten wird, wobei der Festbrennstoff einen Feuchtigkeitsgehalt von < 15% aufweist und die Temperatur im Reaktionsraum auf über 40°C und unter 100°C gehalten wird, und daß die Verbrennung mit einer Feuerbettemperatur von 830°C erfolgt. This object is achieved by a method of solved type mentioned, in which the ground festival fuel with the added basic additive for a duration it from 10 to 180 min in a substantially closed Reaction space is kept, the solid fuel one Has moisture content of <15% and the temperature in the Reaction space is kept above 40 ° C and below 100 ° C, and that the combustion with a fire bed temperature of 830 ° C he follows.
Erfindungsgemäß führt eine ganz ähnliche Behandlung, wie sie für die Verbrennung von Müll vorgeschlagen worden ist, zu ei ner geeigneten Aufbereitung von fossilen Festbrennstoffen, die - im Unterschied zu den bisherigen Verfahrenstechniken - für die Vermischung mit dem basischen Additiv auf eine relativ ho he Feuchtigkeit eingestellt und in einem geschlossenen Reaktionsraum auf eine erhöhte Temperatur eingestellt werden, wobei der Reaktionsraum vorzugsweise indirekt und vorzugswei se auf eine Temperatur von etwa 60°C beheizt wird.According to the invention carries out a treatment very similar to that for the incineration of waste has been proposed to egg suitable processing of fossil solid fuels, the - in contrast to previous process technologies - for mixing with the basic additive to a relatively high he moisture adjusted and in a closed Reaction space can be set to an elevated temperature, wherein the reaction space is preferably indirect and preferably two se is heated to a temperature of about 60 ° C.
Durch eine anschließende Verpressung der Festbrennstoffe las sen sich Briketts oder Pellets herstellen, in denen durch die erwähnten Aufbereitungsmaßnahmen die Schadstoffe, insbesondere Säurebildner zu Salzen mit einer hohen Dissoziationstemperatur gebunden sind, so daß bei einer Verbrennung mit einer Feuer bettemperatur von 830°C die gebundenen Salze in dem Ver brennungsrückstand verbleiben und nicht zu den Schadstoffen dissoziieren.Read through a subsequent compression of the solid fuels briquettes or pellets, in which by the processing measures mentioned the pollutants, in particular Acid generator to form salts with a high dissociation temperature are bound so that when burned with a fire bed temperature of 830 ° C the bound salts in the ver combustion residues remain and not to the pollutants dissociate.
Durch die Erfindung ist es daher möglich, erstmalig auch ver preßte Festbrennstoffe zur Verfügung zu stellen, die mit einer hohen Schadstoffarmut, beispielsweise mit einem SO2-Anteil von weniger als 2%, verbrannt werden können.The invention therefore makes it possible for the first time to also provide compressed solid fuels that can be burned with a low level of pollutants, for example with an SO 2 content of less than 2%.
Zur Durchführung des Verfahrens wird der Feuchtigkeitsgehalt des Gemisches in dem Reaktionsbehälter vorzugsweise auf < 20% eingestellt. Als basisches Additiv eignet sich ein Erdalkali gemisch, vorzugsweise CaCO3 und/oder MgCO3 das im stöchiome trischen Verhältnis von < 1,0 den Festbrennstoffen zugegeben wird.To carry out the process, the moisture content of the mixture in the reaction vessel is preferably set to <20%. A suitable alkaline additive is an alkaline earth mixture, preferably CaCO 3 and / or MgCO 3 which is added to the solid fuels in a stoichiometric ratio of <1.0.
Durch die für Festbrennstoffe ungewöhnliche Aufbereitung durch Einstellung eines vorbestimmten Feuchtigkeitsgehaltes für die Zugabe des basischen Additivs, dem Verbleib des Festbrennstof fes in einem Reaktionsbehälter für eine Zeit von vorzugsweise mehr als 20 min und dem anschließenden Trocken des Fest brennstoffes läßt sich auch bei stark schwefelhaltiger Stein- bzw. Braunkohle eine schadstoffarme Verbrennung erzielen.Due to the unusual treatment for solid fuels Setting a predetermined moisture content for the Add the basic additive, where the solid fuel remains fes in a reaction vessel for a period of preferably more than 20 min and the subsequent drying of the festival fuel can also be used with stone or lignite achieve low-emission combustion.
