- the outlet of the degassing channel i. the end of Garbage transport route, which is realized essentially by the screw conveyor is in contact with the interior of the high-temperature reactor whose Heat is thus practically not transported in the degassing. this applies especially if the screw conveyor before the end of the degassing ends and at the end of a graft from the transported goods is formed.
- the heat supply to the material in the degassing via the this surrounding coat is relatively inefficient. A direct heating of the garbage in the degassing can only occur if this sufficient is dry to allow partial combustion. Garbage with one Moisture content above 30% can not be processed in this way.
- the in the second zone gases and the pyrolysis of the first zone subsequently subjected to secondary combustion. This should be the first Zone are heated by radiant heat, directly from the secondary combustion is won.
- waste is sent via a plug screw transported in a trained as Schweltrommel pyrolysis reactor, wherein the carbonization drum by means of passing through these heating pipes indirectly is heated and thus the cooler heating gas also for heating a Transport channel is used, in which the stuffing screw is arranged (DE 43 27 633 A1). It is therefore an indirect heating, in particular in the area of the transport channel is similarly weak and inefficient as in the Initially discussed prior art. Processing wet waste with a moisture content above 75% is also not effective to perform.
- the heated dried material becomes then in a vaporization chamber with exclusion of air in solid and fluid components of the waste are separated.

- the first phase of sealing by compression of the waste closes
- the waste is dried efficiently and nonetheless safe and without risk of explosion, with progressive warming by direct Contact with the furnace atmosphere of the incinerator.
- the dried one Waste is continued through the furnace atmosphere continuously to one of Pyrolysis required temperature heated in a third phase.
- the trash is moved over the transport path at such a speed that in the third phase with slow pyrolysis of the waste substantially Gas is generated.
- the total residence time of the waste over the transport route can typically be 15 to 20 minutes.
- a fourth phase the burnout of the pyrolyzed waste is completed, and at the latest following the transport screw in a free Area of the furnace interior, in which the pyrolysed waste from the frontal End of the transport screw falls. It will be a complete combustion with achieved little air or oxygen.
- waste moisture by this method to process.
- Under low-moisture waste becomes one with a Water content of up to 15 percent by mass understood. This may be a Changing one or less process parameters required, for example a variation of the transport speed of the waste to be processed along the transport route.
- the inventive method is thus characterized by great universality out.
- Waste according to claim 3 Due to the direct contact with the furnace atmosphere, first at the transport screw and then in the free area of the furnace interior is the Waste according to claim 3 exposed to a temperature above 850 to 1200 ° C, which is certainly sufficient for complete pyrolysis depending on the type of waste.
- a device for carrying out the method according to the invention according to claim 9, which is open at its end-side section at the top, i. exposed Transport screw, which is thermally unshielded in direct contact with the furnace atmosphere is an essential element.
- exposed Transport screw which is thermally unshielded in direct contact with the furnace atmosphere is an essential element.
- the end portion extending into an interior of the incinerator only at the bottom in a shell-shaped shell of refractory Material taken.
- the screw conveyor needs only at her to said end-side Section opposite end to be stored on one side.
- Temperature sensor can approximate the temperature of the with the Transport screw transported waste are detected.
- the signal from the Temperature sensor can be in a furnace temperature-dependent speed control a drive of the screw conveyor according to claim 12 further processed.
- the processing for example, in terms of moisture, density or thermal conductivity different types of waste, optimized.
- the temperature of the screw conveyor the is heated by the furnace atmosphere through the formation of a cooling water passage in the screw conveyor in conjunction with a flow-controlled Cooling water source can be optimized. It has a temperature outside on wings of the screw higher than 250 ° C proved to be expedient.
- the multiple function which is open at the top along an end portion, i. exposed Transport screw along this end portion of the efficient Drying of the waste and the subsequent pyrolysis serves and the moreover in a direction preceding in the transport direction of the waste over the circumference completely closed section acts as a plug screw.
- the inventive device with which the inventive method is carried out generally comprises a screw conveyor 1 in conjunction with a combustion furnace 2.
- the screw conveyor has a variable-speed drive 3 on, with a substantially horizontal transport screw 4 geared is coupled.
- a charging device 6 is arranged, which with waste, in particular Food waste or biosludge fed batchwise or continuously can be.
- the feeder with a slide 7 or instead by blocking air supply with a Air supply pipe 6a lockable to the environment.
- the area of the furnace interior that is not affected by the screw conveyor 4 and the Ofenausmautation 9 is taken in the present application as designated free area 11 of the incinerator. About him can be an alternative Loading lock 15 be placed on the incinerator, which is only indicated in the drawing. Continue to end in the interior Nozzles 12, which use air / oxygen for combustion and heat generation in be fed to the furnace interior.
- the incinerator is closed down in the usual way by an ash bed 14.
- the output signal is a measure of the Temperature of in the adjacent area with the screw conveyor transported waste is and further processed for speed control of the drive 3 becomes.
