- the dried sewage sludge granulate is fed into a cycloid furnace in doses and burned in its swirl flow.
- the non-condensable vapor components are passed into the combustion chamber for thermal deodorization.
- the flue gases emerging from the combustion chamber flow into a waste heat boiler, where they are cooled to approx. 200 ° C.
- the steam generated in the waste heat boiler is fed to the dryer as heating steam.
- a fabric filter for separating the sewage sludge ash is arranged behind the waste heat boiler and the flue gases freed from the ash are then subjected to a flue gas scrubber and leave the plant cleaned.
- furnace basic additive is added, then heat to the flue gas for drying the sewage sludge while cooling the Flue gases to a first temperature above the Extracted condensation temperature of volatile heavy metals is followed by a first dedusting, then the Flue gas heats up again while cooling the flue gas a lower, but above the cooling limit temperature of the Flue gas lying temperature is withdrawn, then the Flue gas fed and another basic additive then the flue gas from a filtering dedusting device is fed.
- the flue gases are preferably cooled from the Combustion temperature to a temperature of 400-500 ° C, more preferably 420-470 ° C, even more preferably 450 ° C, and cooling before further addition of basic Additive to a temperature of 100-150 ° C, of which it is assumed that a temperature of 1000-1100 ° C, preferably 1050 ° C.
- the first dedusting After the first cooling, the first dedusting a mixture of flight dust and that at least partially reacted basic additive deposited. That dust has essentially no condensed heavy metals and their connections. So there are essentially none Products from incomplete combustion because the Heavy metals only at lower temperatures condense out or the products become incomplete Combustion only occurs in the course of a de novo synthesis regress. Consequently, this product can e.g. B. as Soil improver or as an aggregate in construction or Building materials industry can be used. That way the sewage sludge is at least partially recovered. Only the one at the second dedusting dust, which is practical contains all condensed heavy metals, but hardly Organika, must be disposed of.

- the Combustion chamber is a start-up and support burner 8 and one Secondary air supply 9 including a blower 10 assigned. The combustion takes place automatically, i. H. the Burner 8 is usually out of order.
- a basic additive, preferably hydrated lime, from a silo 12 is added to the secondary air SL via an injector 11a.
- a first dry flue gas cleaning stage is realized, since there is a very balanced temperature distribution in the combustion chamber 6, preferably in the range of 900-1050 ° C. With this temperature distribution, very good integration of acidic harmful gas components, in particular SO x , can be achieved with the formation of the corresponding calcium compounds.
- the flue gases then flow through together with the Combustion formed fly ash and at least partially reacted additive a waste heat boiler 13, the in a steam circuit 14 with flow 14a and Return 14b including a circulation pump 15 and a drum 16 in the from FIG. 1 obvious way by means of a feed line 13a from drum 16 and one Discharge line 13b to drum 16 is switched on.
- the design of the waste heat boiler is preferred as Saturated steam smoke tube boiler, as shown in FIG. 1 shown is.
- the double jacket 3a of the dryer is steamed pressurized and the condensate that forms over the pump 15 returned to the drum.
- a first temperature preferably 450 ° C
- flow through the Flue gases include a dust collector, which is preferably used as a High temperature cyclone 17 is formed.
- High temperature cyclone 17 are 90%, but still preferred more of the carried mixture of dust and reacted additive deposited as the first product 18.
- This product contains practically no condensed ones Heavy metals and their compounds, as well as no products incomplete combustion.
- the high-temperature dedusting in cyclone 17 follows Heat exchanger 19 in which heat on water, steam, air or the like is transmitted.
- Heat exchanger 19 heat on water, steam, air or the like is transmitted.
- water from the Waste heat boiler 13 associated steam cycle be preheated.
- the flue gas to the operating temperature of a downstream second dry flue gas cleaning stage is cooled.
- the operating temperature of this Flue gas cleaning level is above Cooling limit temperature (adiabatic saturation temperature) of Flue gases, preferably in the range of 100-150 ° C.
- the second dry flue gas cleaning stage is over an injector 11b also acted upon by the blower 10 via line 22 basic additive, preferably Calcium hydrate, injected upstream of a fabric filter 23.
- the second flue gas cleaning stage represents the acidic harmful gas components and the substance one Fine cleaning. Forms in the fabric filter 23 a filter auxiliary layer for the separated solids. The due to the quenching there was water enrichment in the Flue gas is for the separation performance of the fabric filter 23 conducive.
- the solids separated in the fabric filter can over a rotary valve 24 and a return line 25 back recirculated into the flue gas stream in front of the fabric filter 23 become.
- a partial stream 26 is discharged.
- the second dry flue gas cleaning stage is followed by an activated coke filter 27 which relates to Dust and acid pollutant components one Police filter function fulfilled. Regarding mercury and Organika fulfills the fine cleaning function.
