Abstract

It is known that liquid manure (slurry) from agricultural enterprises can lead to soil and groundwater contamination. In order to avoid these disadvantages, according to the invention it is proposed that the liquid manure is fed to a furnace installation which operates with a base load preferably in the coal section and the ashes thereof and types of lime fed in neutralise SO2 and odours in the furnace part and simultaneously apply a precoat layer in a downstream cloth filter, which precoat layer is preferably supplemented by the addition of further fresh lime. The furnace installation used is preferably a fluidised-bed furnace. The furnace installation, which is operated with fossil fuels, is supplied with liquid manure at more than 5% by weight.

Description

Es ist bekannt, daß Gülle aus Landwirtschaftsbetrieben Boden- und Grundwasserverunreinigungen bewirken kann.It is known that manure from farms Soil and groundwater contamination can cause.

Aus diesem Grunde wird erfindungsgemäß vorgeschlagen, eine Wirbelbettfeuerungsanlage, die z. B. mit Kohle betrieben wird und außer SO2 und Staub auch NO x freisetzt, mit Gülle zu besprühen. Durch diese er­ findungsgemäßen Maßnahmen wird erreicht, daßFor this reason, the invention proposes a fluidized bed combustion system, the z. B. is operated with coal and apart from SO 2 and dust also releases NO x , to be sprayed with liquid manure. Through these measures he inventively ensures that

  • 1. die Gülle umweltfreundlich verbrannt wird, da das Wirbelbett durch Zugabe von Kalk und einem nachgeschalteten Gewebefilter, auf dem Kalk­ hydrat und Filterasche precoatisiert aufgefahren sind, die Trockensubstanzen der Gülle, die durch das Verbrennen in Form von Asche freigesetzt werden, ebenfalls auf dem Filter nichtriechend mitabscheidet.1. The manure is burned in an environmentally friendly way, because the fluidized bed by adding lime and a downstream fabric filter, on the lime hydrate and filter ash accumulated precoated are the dry matter of the manure, which is caused by  the burning in the form of ash is released are also not smelling on the filter co-deposits.
  • 2. Es wurde gefunden, daß die Gülle eine NO x - Reduktion im Wirbelbett bewirkt.2. It has been found that the manure brings about a NO x reduction in the fluidized bed.

Es ist erfindungsgemäß gefunden worden, daß bei etwa 10% der gewichtsmäßigen Einbringung eines fossilen Brennstoffes wie z. B. Kohle, Öl, Gas und/oder anderer pelletisierter Brennstoffe wie Müll und dergleichen Gülle eine NO x -reduzierende Wirkung bringt.It has been found according to the invention that at about 10% by weight of a fossil fuel such. B. coal, oil, gas and / or other pelletized fuels such as garbage and the like manure brings a NO x -reducing effect.

Selbstverständlich ist die Erfindung nicht auf die vorstehend im einzelnen beschriebenen Ausbildungs­ formen beschränkt, sondern es sind zahlreiche Abän­ derungen möglich, ohne jedoch von dem Grundgedanken abzuweichen, Gülle einer Feuerung, vorzugsweise Wirbelbettfeuerung, direkt zuzuführen oder im Bereich des Brenners oder über den Brennstoff, z. B. über die Kohle durch Zugabe von Kalk im Feuerungsraum und/oder SO2-freiwerdenden Substanzen des gesamten zu verbrennen­ den Materials zu binden, wobei mit dem sich bildenden Rückstand aus dem Kalk, wie CaSO3 und CaSO4 und der Filterasche über dem nachgeschalteten Gewebefilter eine Precoatisierungsschicht erzeugt wird, die die Reststoffe der verbrannten Gülle ebenfalls aufnimmt und umweltfreundlich und nichtriechend der Asche zu­ führt.Of course, the invention is not limited to the training forms described above in detail, but there are numerous changes possible, but without deviating from the basic idea of supplying liquid manure to a furnace, preferably fluidized bed combustion, or in the area of the burner or via the fuel, for . B. over the coal by adding lime in the furnace and / or SO 2 -free substances to burn the entire material to bind, with the residue formed from the lime, such as CaSO 3 and CaSO 4 and the filter ash over the downstream Fabric filter a precoating layer is generated, which also absorbs the residues of the burned manure and leads to the ashes in an environmentally friendly and non-smelling way.

Weiterhin kann die Gülle mit anderen aus der Tierhaltung anfallenden Rückständen gemischt werden, z. B. mit Pferdemist.Furthermore, the manure can be used with other animals accumulating residues are mixed, e.g. B. with Horse manure.
