Description

Die Erfindung betrifft ein Verfahren zum Betreiben einer Anlage zum Verfeuern von Kohle wie beispielsweise eines Kohlekraftwerkes zum Erzeugen von Wärmeenergie oder elektrischer Energie.The invention relates to a method for operating a plant for burning coal such as a coal-fired power plant for generating thermal energy or electrical energy.

Es ist seit jeher das Bestreben gewesen, bei Anlagen zum Verfeuern von Kohle, insbesondere Kohlekraftwerken den Wirkungsgrad, d. h. das Verhältnis der erzeugten Energie zu dem Kohleverbrauch möglichst hoch zu halten. Hierzu wird Kohle in unterschiedlicher Form beispielsweise in Form von gepressten Formkörpern, beispielsweise Briketts, in Staubform oder in Granulatform verfeuert. Bei dieser Art des Betriebs einer Anlage zum Verfeuern von Kohle kommt es zu einer erheblichen Feinstaubentwicklung während der Vorbereitung der Kohle, der Lagerung der Kohle, und im Kraftwerk selbst während ihres Transportes, insbesondere zur Brennstelle und während des Abbrandes. Es ist weiterhin nachteilig, dass Kohle während der Lagerzeit Wasser aufnimmt, da dieser Wasseranteil den Heizwert herabsetzt.It has always been the desire, in coal burning plants, especially coal-fired power plants, to increase the efficiency, ie. H. To keep the ratio of the generated energy to the coal consumption as high as possible. For this purpose, coal is fired in different forms, for example in the form of pressed moldings, for example briquettes, in dust form or in granular form. In this type of operation of a coal-burning plant there is a considerable development of fine dust during the preparation of the coal, the storage of the coal, and in the power plant itself during its transport, in particular to the burning point and during the burn-up. It is also disadvantageous that coal absorbs water during storage, as this proportion of water reduces the calorific value.

Die der Erfindung zugrunde liegende Aufgabe besteht daher darin, ein Verfahren zum Betreiben einer Anlage zum Verfeuern von Kohle anzugeben, mit dem die Kohle bei einem hohen Heizwert nahezu vollständig ohne wesentliche Feinstaubbelastung verfeuert werden kann.The object underlying the invention is therefore to provide a method for operating a plant for burning coal, with which the coal at a high calorific value can be almost completely burned without significant particulate matter pollution.

Diese Aufgabe wird gemäß der Erfindung durch das Verfahren gelöst, das im Patentanspruch 1 angegeben ist.This object is achieved according to the invention by the method specified in claim 1.

Besonders bevorzugte Ausbildungen und Weiterbildung des erfindungsgemäßen Verfahrens sind Gegenstand der Patentansprüche 2 bis 7.Particularly preferred embodiments and development of the method according to the invention are the subject of claims 2 to 7.

Im Folgenden wird ein besonders bevorzugtes Ausführungsbeispiel des erfindungsgemäßen Verfahrens beschrieben.In the following, a particularly preferred embodiment of the method according to the invention will be described.

Zum Betreiben einer Anlage zum Verfeuern von Kohle wird zunächst die Kohle in Form von Holzkohle, Braunkohle oder Steinkohle zu Formkörpern verpresst, in Staubform gemahlen oder in Granulatform gebracht. Auch Mischungen dieser Formen sind möglich. Gleichfalls ist es möglich der Kohle Holzkleinteile beizumischen oder Beimischungen zuzugeben, die in Biomassen-, Holz- und Kohlekraftwerken jeglicher Art verbrannt werden können.To operate a coal-burning plant, the coal is first pressed in the form of charcoal, lignite or hard coal into shaped bodies, ground in dust form or in granular form brought. Also mixtures of these forms are possible. It is also possible to add to the coal wood small parts or add admixtures that can be burned in biomass, wood and coal power plants of any kind.

Im nächsten Verfahrensschritt der Vorbereitung bzw. Veredelung der Kohle wird auf diese bzw. auf die in dieser Weise gebildete Mischung eine Emulsion aufgebracht, die aus Stearinsäure und Palmitinsäure besteht. Insbesondere besteht diese Emulsion aus 50 bis 60 Gewichts- oder Volumen% Palmitinsäure, 40 bis 50 Gewichts- oder Volumen% Stearinsäure, max. 1 Gewichts- oder Volumen% Laurinsäure und max. 3 Gewichts- oder Volumen% Myristinsäure.In the next step of preparing or refining the coal, an emulsion consisting of stearic acid and palmitic acid is applied to this or to the mixture formed in this way. In particular, this emulsion consists of 50 to 60% by weight or by volume of palmitic acid, 40 to 50% by weight or by volume of stearic acid, max. 1% by weight or volume of lauric acid and max. 3% by weight or volume% myristic acid.

Die Emulsion kann aber auch aus 42 Gewichts% Palmitinsäure, 5 Gewichts% Stearinsäure, 41 Gewichts% Ölsäure, 2 Gewichts% Myristinsäure und 10 Gewichts% Linolsäure bestehen.However, the emulsion may also consist of 42% by weight of palmitic acid, 5% by weight of stearic acid, 41% by weight of oleic acid, 2% by weight of myristic acid and 10% by weight of linoleic acid.

Diese Emulsion erhöht den Heizwert der Kohle oder auch der Holzkleinteile oder Biomasse um ca. 15 bis 40 %.This emulsion increases the calorific value of the coal or even the wood small parts or biomass by about 15 to 40%.

Die Emulsion wird vorzugsweise dadurch aufgebracht, dass sie bei einer erhöhten Temperatur aufgespritzt wird. Sie kann aber auch im kalten losen oder erstarrten Zustand beigemischt oder mit der Rohkohle vermengt werden. Die Temperatur der Emulsion beträgt dabei insbesondere 50 bis 120°C.The emulsion is preferably applied by being sprayed at an elevated temperature. But it can also be mixed in the cold loose or solidified state or mixed with the raw coal. The temperature of the emulsion is in particular 50 to 120 ° C.

Die oben angegebene spezielle Zusammensetzung und Temperatur der Emulsion ermöglicht ein schnelles Einziehen der Emulsion in die Rohkohle sowie eine schnelle Abkühlung an der Außenseite der Kohle, so dass sich dort über eine Aushärtung der Emulsion eine die Kohleteile umschließende Schicht ergibt, die wasserundurchlässig ist. Die Temperatur im Inneren der Kohleteile, die durch die äußere ausgehärtete Emulsionsschicht versiegelt sind, bleibt demgegenüber weitgehend erhalten, da die Kohleteile über die entstandene Außenschicht wärmeisoliert sind. Die Temperaturabnahme im Inneren der Kohleteile verläuft schwach linear über einen Zeitraum von ca. 12 Stunden oder mehr. Während dieser Zeit bleibt das Innere der Kohleteile auf einer gegenüber der Umgebungstemperatur erhöhten Temperatur.The above specific composition and temperature of the emulsion allows the emulsion to be rapidly drawn into the raw coal and to be rapidly cooled on the outside of the coal, so that over curing of the emulsion there results a layer enclosing the coal parts, which is impermeable to water. The temperature in the interior of the coal parts, which are sealed by the outer cured emulsion layer, however, largely retained, since the coal parts are thermally insulated on the resulting outer layer. The temperature decrease inside the coal parts runs weakly linear over a period of about 12 hours or more. During this time, the interior of the coal parts remains at a temperature higher than the ambient temperature.

Gemäß der Erfindung wird die Kohle nach der oben beschriebenen Vorbereitung anschließend in einem Zustand verfeuert, in dem ihre Innentemperatur noch über der Umgebungstemperatur liegt. Aufgrund der erhöhten Eigentemperatur im Inneren der Kohleteile ist der Energiebedarf zum Entzünden der Kohle geringer als bei unbehandelter Kohle, d. h. bei Kohle ohne die erfindungsgemäß vorgesehene Emulsion. Für die Verbrennung der Kohle mit der Emulsion muss daher weniger Energie aufgewendet werden.According to the invention, the coal is then burned according to the preparation described above, in a state in which its internal temperature is still above the ambient temperature. Due to the increased temperature inside the coal parts, the energy required to ignite the coal is lower than for untreated coal, d. H. in the case of coal without the emulsion provided according to the invention. For the combustion of the coal with the emulsion therefore less energy must be expended.

Durch die Zugabe der Emulsion und deren oben beschriebene Eigenschaft der schnellen Abkühlung zur Bildung einer Außenschicht wird die Oberfläche der Kohleteile gehärtet, was zu einer Verringerung der Feinstaubentwicklung bei der Lagerung, bei der Verpackung, dem Transport und der Verarbeitung führt. Auch während des Verbrennungsprozesses wird die Feinstaubbelastung durch die Ummantelung der Kohleteile mit der zusätzlich zugegebenen Emulsion verringert. Die Emulsion bindet weiterhin lose Feinteile in und an den Kohleteilen und verhindert dadurch das thermische Aufsteigen vor und während der Verbrennung der Kohle. Auch das trägt zur Feinstaubreduktion bei. Der sonst bei unbehandelter Kohle entweichende Feinstaub wird bei Kohle, die erfindungsgemäß mit der Emulsion behandelt wurde, größtenteils mitverbrannt. Hierdurch wird eine nahezu vollständige Verbrennung erzielt.The addition of the emulsion and its rapid cooling property described above to form an outer layer, hardens the surface of the coal parts, resulting in a reduction of particulate development during storage, packaging, transportation and processing. Also during the combustion process, the particulate matter load is reduced by the shell of the coal parts with the additionally added emulsion. The emulsion further binds loose fines in and on the coal parts and thereby prevents thermal rise before and during the combustion of the coal. This also contributes to the reduction of particulate matter. The otherwise escaping with untreated coal particulate matter is charcoal, which was treated according to the invention with the emulsion, most of the co-incinerated. As a result, an almost complete combustion is achieved.

Die Außenschicht auf den Kohleteilen, die durch Aushärten der Emulsion gebildet wird, ist wasserundurchlässig, so dass die Aufnahme von Wasser, die bei unbehandelter Kohle unvermeidlich ist und die zu einer Abnahme des Heizwertes führt, vermieden wird. Die Außenschicht hat eine wasserabweisende und/oder versiegelnde Funktion.The outer layer on the coal particles, which is formed by curing of the emulsion is impermeable to water, so that the uptake of water, which is unavoidable in untreated coal and which leads to a decrease in the calorific value, is avoided. The outer layer has a water-repellent and / or sealing function.

Aufgrund der hohen Temperatur der Emulsion und deren wasserverdrängender Eigenschaft wird weiterhin ein Großteil des sich in der Kohle befindlichen Wassers verdrängt. Die Kohle wird anschließend mit der wasserabweisenden Emulsionsschicht ummantelt, so dass eine erneute Wasseraufnahme nahezu unmöglich ist. Der geringe Wasseranteil in der zu verbrennenden Kohle führt dann zu einem höheren Energiewirkungsgrad.Due to the high temperature of the emulsion and its water-displacing property continues to be displaced a large part of the water in the coal. The coal is then coated with the water-repellent emulsion layer, so that a renewed water absorption is almost impossible. The low water content in the coal to be burned then leads to a higher energy efficiency.

Die Emulsion basiert auf biologischen Materialien und erhöht den Heizwert der behandelten Kohle. Sie führt zu einer Verminderung des Schadstoffausstoßes und einer Verringerung der Feinstaubbelastung in Biomasse, Holz- und Kohlekraftwerken, während des Verbrennungsvorgangs sowie auch beim Transport, der Verarbeitung und der LagerungThe emulsion is based on biological materials and increases the calorific value of the treated coal. It leads to a reduction in pollutant emissions and a reduction of particulate matter in biomass, wood and coal power plants, during the combustion process as well as during transport, processing and storage

Die mit der Emulsion veredelte Kohle kann auch als spezielle Grillkohle verwendet werden, welche bei Verpackung, Transport und Anwendung die Feinstaubbelastung reduziert und dadurch geringere bis keine Verunreinigungen bei der Anwendung als Grillkohle verursacht. Es wird festgehalten, dass diese besondere Kohle bessere Entzündungseigenschaften als herkömmliche Grillkohle besitzt, welche weniger bis keine Brandbeschleuniger zur Entflammung gegenüber herkömmlicher Grillkohle benötigt.Coal refined with the emulsion can also be used as a special charcoal which reduces particulate pollution during packaging, transportation and application, thereby causing less to no contamination when used as charcoal. It is noted that this particular coal has better ignition properties than conventional charcoal, which requires less to no fire accelerant to ignite over conventional charcoal.
