Definitions
- the coming of the gas burner fuel gas must have a relatively high temperature in a DC operation, especially in the beginning of the rotary kiln, since the regenerated foundry sand must have a temperature of more than 700 ° C when leaving the rotary kiln. Since the drum atmosphere cools down in the conveying direction or flow direction, adequate starting temperature must be provided accordingly at the beginning. However, this leads in particular in the initial region of the furnace drum to high demands on the temperature resistance of the furnace material, which also leads to high costs.
- a uniform temperature profile in the furnace drum can be achieved by the combination of direct heating of the drum space, as is known, for example, using a gas burner, with indirect heating of the drum space via its drum wall.
- direct heating of the drum space as is known, for example, using a gas burner
- indirect heating of the drum space via its drum wall in particular, a cooling of the flue gases on the way through the kiln drum can be prevented.
- the temperature at the direct heater compared to a direct heating alone can be reduced, whereby the requirements for the furnace material are less high. An afterburning of the flue gases is then not necessary because they have a sufficiently high temperature at the exit from the furnace drum.
- the rotary kiln By the heating gas is passed at the drum inlet of the furnace drum in the drum space, the rotary kiln can be operated based on direct heating on the DC principle.
- the drum wall is heated by a heating medium is passed from the outside to the drum wall.
- the heating medium is conducted in a direction from the drum outlet to the drum inlet of the furnace drum on the outside of the drum wall. Based on the conveying direction of the material through the furnace drum, the indirect heating thus takes place according to the countercurrent principle.
- the kiln drum in its longitudinal direction be heated with opposite temperature gradient, so that a total of a homogeneous temperature profile is constructed in the drum room. So that the heating medium flows over the drum wall in a targeted manner, this is favorable when the heating medium is passed through an annular space surrounding the oven drum.
- the maximum temperature prevailing locally in the drum space in particular in the area of direct heating, can be lowered.
- an oven drum is used, of which at least the drum wall and / or a conveying structure on the inner lateral surface of the drum wall are made of steel. The steel used is selected depending on the temperatures reached in the drum room.

- the indirect heating device comprises a burner unit, by means of which a heating medium can be generated, and at least one line through which the heating medium can be conducted to the drum wall from the outside.
- a heating medium can be generated, and at least one line through which the heating medium can be conducted to the drum wall from the outside.
- the indirect heater comprises a flow path through which the heating medium in the direction of the drum outlet on the drum inlet of the furnace drum outside the drum wall is guided along.
- the flow path for the heating medium can advantageously be provided by the indirect heating device comprising a cladding tube with an inlet connection for heating medium and an outlet connection for heating medium, which is arranged coaxially with the oven drum such that an annular space surrounding the oven drum is formed, by which heating medium indirect heating device is conductive.
- a helical guide structure is arranged in the annular space so that the heating medium flows in a helical manner from the inlet connection to the outlet connection and around the oven drum. In this way it can be ensured that all areas of the furnace drum are uniformly and selectively overflowed by heating medium.
- At least the drum wall and / or a conveying structure on the inner lateral surface of the drum wall can be made of steel from the furnace drum.
- FIG. 1 10 generally designates a system shown schematically for the thermal treatment of a material.
- the material to be processed can be, for example, foundry sand or even road-breaking material.
- the system 10 has a rotary kiln 12, which initially based FIG. 2 is explained, which shows the rotary kiln in more detail, but also only schematically.

- the supply nozzle 32 is illustrated as a dashed arrow.
- a burner unit 34 in the form of a gas burner 36 is arranged on the input flange 30, which has a Fuel gas line 38 is supplied with fuel gas from a not specifically shown fuel gas source. Via an air line 40 the gas burner 36 is supplied for its operation required burner air.
- the gas burner 36 generates in a manner known per se and heating gas, which is passed in a direction indicated by an arrow heating gas flow direction 42 in the drum chamber 22, flows through it and heated directly.
- the furnace drum 14 opens at the drum outlet 28 into an outlet flange 44, which comprises a flue gas outlet 46 and a material outlet 48.
- a flue gas outlet 46 and a material outlet 48.
- resulting flue gas flows from the drum chamber 22 into the output flange 44 and from there via the flue gas outlet 46 in a flue gas duct 50; This will be discussed again below.
- the drum wall 24 On its inner circumferential surface, the drum wall 24 carries a conveyor structure 52, for example a continuous conveyor coil 54.
- a conveyor structure 52 for example a continuous conveyor coil 54.
- material entering the drum space 22 through the supply nozzle 32 is conveyed therethrough in a conveying direction 56 by the conveyor coil 54
- Material outlet 28 of the furnace drum 14 promoted where it enters the output flange 44 and is discharged through the material outlet 48.
- the conveyor coil 54 may still include parallel to the longitudinal axis 18 extending and radially inwardly projecting sheets, which are not shown here specifically. These sheets take the material with the rotation of the kiln drum 14 initially up with, until the material drops again when reaching a certain height from the sheets down. This is compared to a conveyor coil 18 without such additional sheets achieved an even better mixing of the material.
- the rotary kiln 12 is consequently operated in the so-called DC process.
- FIG. 1 shows the flue gas is guided from the output flange 44 via the flue gas line 50 in a dust removal device 58. From there, the now dedusted flue gas passes into an adjustable distribution unit 60, by means of which a portion of the purified flue gas is directed into the air line 40 to the gas burner 36 and the remaining portion of the purified flue gas can be removed via a line 62.
- the distribution unit 60 can also fresh air from a fresh air line 64 are passed with a fresh air blower 66 in the air line 40, so that the ratio of a mixture of purified flue gas and fresh air can be adjusted, which then passes as combustion air to the gas burner 36.
- the combustion air can thus be provided by pure purified flue gas, pure fresh air or by a mixture of flue gas and fresh air in an adjustable ratio.

Via an air line 80 the burner gas required for the operation of the second gas burner 76 is supplied.
- the heating medium of the indirect heater 72 is also a heating gas.
- This heating gas is passed via a Walkergas Gustav 82 to the drum wall 24 of the furnace drum 14, where it can flow along the outside.
- the furnace drum 14 is surrounded by an annular space 84, which is formed by that a cladding tube 86 is arranged coaxially with the furnace drum 14.
- the cladding tube 86 includes an input port 88 and an output port 90 for heating medium so that the annulus 84 provides a flow path to the fuel gas of the second gas burner 76.
- the input port 88 is disposed at the end of the cladding tube 86, which faces toward the output flange 44 of the rotary kiln 12.
- the output port 90 is located at the end of the cladding tube 86 facing toward its input flange 30.
- the input port 88 is connected to the Schugas effet 82 of the second gas burner 76, so that the heating gas generated by this in a counter-flow direction 92 outside the drum wall 24 is guided along, which points from the drum outlet 26 to the drum inlet 28 of the furnace drum 14.
- the indirect heating device 72 Based on the conveying direction 56 of the material to be processed and the flow direction 42 of the heating gas of the first gas burner 36 through the drum space 22, the indirect heating device 72 thus follows the countercurrent principle.
