2 and 10 on pages 97-120, especially page 101.
(See the explanatory note on page 3). In this known plant, the total low-temperature carbonized gas produced is converted into a clean gas in a gas converter downstream of a washing channel. Part of this clean gas is burned in the combustion chamber. The flue gas generated at that time is led into a substantially open-loop circuit and used as heating gas for the low-temperature carbonization drum. This method is particularly expensive anyway,
It is even more uneconomical as clean gases already economically available are used for the production of heated gases.

される必要がある。Accordingly, an object of the present invention is to provide an economical method of heating a low-temperature carbonized drum in which a sufficient amount of heat is always introduced into the low-temperature carbonized drum by a heating gas. The challenge is
There is a need to solve this with a significantly simpler heating device that guarantees the supply of the heating gas required for the self-sufficient operation of a low-temperature carbonization plant.

に不足熱量を供給するために、低温乾留ドラムから流出
する冷却された加熱ガスは最初に予熱される。It is advantageous if the partial stream of cold carbonization gas is dedusted before combustion. Nevertheless, during operation of the low-temperature carbonization plant, dust can accumulate in the heating gas circuit, especially in the low-temperature carbonization drum. The amount of accumulated dust can be reduced by reducing the partial flow of the low-temperature carbonized gas to be burned. This in any case reduces the amount of heat introduced into the low temperature carbonization drum by the heating gas. In order to supply the heating gas with a lack of heat, the cooled heating gas flowing out of the low-temperature carbonization drum is first preheated.

又は予熱後に加熱ガス回路から分岐される。Subsequently, the preheated heated gas is fed back to the cold distillation drum together with the burned partial stream of the cold distillation gas.
A partial stream of the heating gas flowing out of the low-temperature carbonization drum is branched off from the heating gas circuit before or after the preheating.

防止される。It is advantageous if a partial stream of the low-temperature carbonization gas is guided by the negative pressure prevailing in the heating gas circuit. Such means are used, on the one hand, to convey a partial stream of the low-temperature carbonization gas and the produced heating gas into the heating circuit. On the other hand, in the case of a leak, the leakage of the low-temperature carbonized gas or the heated gas to the surroundings is prevented.

There is a point that can be.
This low-temperature carbonization plant is suitable for retrofitting to an existing combustion plant. In that case, the remaining low-temperature carbonized gas and the remaining material obtained from the low-temperature carbonized drum can be burned in the combustion plant. In doing so, a lateral connection between an existing combustion plant and a previously installed or later installed low-temperature carbonization plant is used, as is required, for example, in the prior art of EP-A-0340537. Thus, it is not necessary to transfer heat or material to heat the low temperature carbonization plant.

び混入される。When the valves 23, 25 are closed, the heated gas g from the low-temperature carbonization drum 4 is led into the circuit 72, mixed with the flue gas before the waste heat boiler 36 via the valve 49, the conduit 41 and the valve 46. Through the waste heat boiler 36 and into the flue gas. In that case, purification of the mixed gas is performed only in the purification device 42. Now, the heated gas circuit 72 forms a closed loop via the conduit 47 and the valves 48, 50, in which case the heat exchanger 80 'is located in the conduit 47.
In this case, on the discharge side of the blower 44, clean flue gas is withdrawn and preheated in the heat exchanger 80 'arranged in the conduit 47. Subsequently, the preheated flue gas is mixed back into the heating gas g.
