Abstract

In order to convert sewage sludge, which is not readily disposable, into an environmentally friendly intermediate product suitable for intermediate storage, according to the invention it is proposed that the sewage sludge is mixed with highly volatile coal having a volatile fraction of more than 28%, and is used in a degassing process for producing a fuel product (coke) suitable for intermediate storage. Apart from the coal, refuse can also be added. The admixed coal portion is more than 10%. The degassing process is carried out in such a manner that the coke produced still has a high portion of volatile constituents, is flammable and can be used as fuel in known plants, such as power station boilers, fluidised bed furnaces etc.

Weiterhin ist bekannt, daß Klärschlamm in der Regel kontinuierlich anfällt und auch genutzt werden sollte.It is also known that sewage sludge is usually continuous accrues and should also be used.

Aus diesem Grunde wird erfindungsgemäß vorgeschlagen, den Klärschlamm in den Sommermonaten bevorzugt mit Kohle und/oder Müll zu mischen, um bei einer Temperatur von vorzugsweise unter 650 0C zu entgasen und hierbei gleichzeitig einen marktfähigen, umweltfreundlichen Koks herzustellen, der in den Sommermonaten zwischengelagert werden kann, um in den Wintermonaten nutzbringend nergetisch Anwendung finden zu können Erfindungsgemäß wird weiter vorgeschlagens daß Kohle, die verwendet wird, fiochflüchtig 4 zugsweise über 28 % flücheig@ Bestandtelle e @ und der Entgasungsprozeß so gesteuert wird, d anfallende Koks noch einen hohen Anteil an flüch tigen Bestandteilen besitzt Hierdurch wird erreicht, daß das Rückstandsprodukt, der sog. Koks, zündfähig ist und in bekannten Anlagen wie Kraftwerkskesseln, Wirbelbettfeuerungen usw Anwendung finden kann Die freigesetzte Gasmenge beim Entgasungsprozeß kann vorzugsweise zur Trocknung des Klärschlamms genutzt werden.For this reason, the invention proposes the sewage sludge in the summer months preferably to mix with coal and / or garbage in order to get a To degas temperature of preferably below 650 0C and at the same time a Produce marketable, environmentally friendly coke, which is temporarily stored in the summer months will can to be beneficial energetically application in the winter months to be able to find According to the invention it is further proposed that coal is used becomes, fiochvolatile 4 preferably over 28% volatile @ constituents e @ and the degassing process is controlled in such a way that the coke produced still has a high proportion of volatile constituents This ensures that the residue product, the so-called coke, is ignitable is and is used in known systems such as power plant boilers, fluidized bed furnaces, etc. The amount of gas released during the degassing process can preferably be used Drying of the sewage sludge can be used.

Hierdurch ist die Gewähr gegen p, daß eine Umwandlung von schwer deponierbarem Klärschlamm auch in den Sommermonaten ohne Energieabg;abe in ein zwischenlagerungsfähiges, umweltfreundliches Zwischenpro dukt übergeführt wird, um in den Heizmonaten oder in den Monaten, wo der Energiebedarf anfällt, zur Verfügung zu stehen.This guarantees against p that a conversion from sewage sludge that is difficult to dispose of even in the summer months without energy output; an environmentally friendly intermediate product that can be temporarily stored is transferred, to be available in the heating months or in the months when the energy demand arises to stand.
