Abstract
Description
Die Druckschrift
Diese Verfahrensweise ist für größere Anlagen oder Neuanlagen wegen ihres Bau- bzw. Änderungsaufwand geeignet.This procedure is suitable for larger plants or new plants because of their construction or modification costs.
Für bestehende Anlagen mit Tunnelöfen z. B. zum Brennen von Ziegelerzeugnissen, Schamotte oder Steinzeug werden verschiedenliche öl- oder gasbetriebene Stromaggregate benutzt um billigere Elektroenergie so zu erzeugen dass die Abwärme der eingesetzten Verbrennungskraftmaschinen (Motoren, Gasturbinen) für Trockenzwecke verwendet wird. Diese Art Kraft-Wärmekopplung erfordert aber Wärmetauscheinrichtungen die bei Ölbetrieb der Stromaggregate Korrosion, Versottung und Reinigungsaufwand erfordert. Außerdem muss die Abwärmemenge der Aggregate begrenzt werden, da die Tunnelöfen ebenfalls schon Abwärme für Trockenzwecke liefern, um eine Überversorgung der Trockenanlage mit Wärme zu vermeiden.For existing systems with tunnel kilns z. As for burning of bricks, chamotte or stoneware different oil or gas powered generators are used to produce cheaper electric energy so that the waste heat of the internal combustion engines used (engines, gas turbines) is used for dry purposes. However, this type of combined heat and power requires heat exchanging devices that require corrosion, sooting and cleaning during oil operation of the generators. In addition, the waste heat quantity of the aggregates must be limited, since the tunnel kilns also already provide waste heat for dry purposes, in order to avoid over-supply of the drying plant with heat.
Wünschenswert ist aber eine Eigenvollversorgung des keramischen Betriebes mit Elektroenergie und auch noch eine Netzeinspeisung in Spitzenstromzeiten zur Netzentlastung. Somit könnten teuere neue Fernnetze entlastet werden zum Transport von regenerativer Energie.However, a self-sufficient supply of the ceramic operation with electrical energy and also a mains supply in peak current times for grid relief is desirable. Thus, expensive new long-distance networks could be relieved to transport renewable energy.
Beim Keramischen Betrieb lassen sich auch Produktionszeiten tagsüber so verschieben, dass eine verstärkte höhere, lokale Netzeinspeisung bei Windflaute und/oder Sonnenarmut erfolgen kann, während Brenn- und Trockenprozesse wie üblich kontinuierlich über 24 Stunden im Tag betrieben werden und den geringeren Verbrauch an Elektroenergie aufweisen, können Aufbereitung- und Formgebungsmaschinen zeitweise zu oder abgeschaltet werden.During the ceramic operation, production times can also be shifted during the day in such a way that increased, local grid feed-in in the event of wind and / or solar poverty can occur, while firing and drying processes are continuously operated as usual over 24 hours a day and have the lower consumption of electrical energy. Processing and forming machines can be temporarily switched on or off.
Aufgabe der Erfindung ist es daher ein Verfahren mit Vorrichtung anzugeben, bei dem eine höhere Energieeffizienz bei der Herstellung keramischer Erzeugnisse erzielt wird, das auch für kleinere Produktionsanlagen geeignet ist und eine elektrische Vollversorgung oder darüber hinaus für die Anlage erlaubt. Außerdem sollen die entstehenden Abgase aus ökologischen Gründen einen hohen Reinheitsgrad aufweisen.The object of the invention is therefore to provide a method with device in which a higher energy efficiency is achieved in the production of ceramic products, which is also suitable for smaller production plants and a full electrical supply or beyond for the plant allowed. In addition, the resulting exhaust gases for ecological reasons have a high degree of purity.
Der in Durchlauföfen üblich angewandte horizontale Gasgegenstrom soll teilweise durch den Abgasstrom aus Verbrennungskraftmaschinen, mit denen elektrische Energie erzeugt wird, ersetzt werden.The usual in continuous furnaces horizontal gas countercurrent is to be partially replaced by the exhaust gas flow from internal combustion engines, with which electrical energy is generated.
Es soll im Durchlaufofen nur noch Verbrennungsluft entsprechend dem restlichen Heizbedarf des Durchlaufofens eingesetzt werden.It should be used in the continuous furnace only combustion air corresponding to the remaining heating demand of the continuous furnace.
Ziel der Erfindung ist im einzelnenThe aim of the invention is in detail
- A) die Erhöhung der Energieeffizienz bei der Herstellung von insbesondere baukeramischen Produkten mit Durchlauföfen mittels Beikopplung von Verbrennungskraftmaschinen welche Stromerzeuger für Eigenstromerzeugung antreiben.A) the increase in energy efficiency in the production of particular structural ceramic products with continuous furnaces by means of coupling of internal combustion engines which power generators for own power generation.

- D) Kontinuierliches Brennen unter reduzierender Ofenatmosphäre zur Erhöhung der Silikatbildung und Verbesserung der Brennprodukte.D) Continuous firing under reducing furnace atmosphere to increase silicate formation and improve the firing products.
- E) Vorzugsweiser Einsatz von Gasturbinen zum Antrieb des Stromaggregates zur restlosen Nutzung der hochtemperierten Abgasströme (ca. 500–700°C) zum Wärmetransport für die Längsströmung im Durchlaufofen.E) Preferably use of gas turbines for driving the generator set for the complete use of the high-temperature exhaust gas streams (about 500-700 ° C) for heat transport for the longitudinal flow in a continuous furnace.
