Abstract
A thermal postcombustion device includes, in a conventional manner per se, a housing, having an inlet for the exhaust air that is to be purified and an outlet for clean air. A combustion chamber is located inside the housing, and inside this combustion chamber, a heating device generates a temperature at which the pollutants carried by the exhaust air burn. In order to reduce the energy requirement, a heat exchanger is provided over which the exhaust air coming from the inlet is guided to the combustion chamber, and the clean air coming from the combustion chamber is guided to the outlet. In order to also be able to process exhaust air, which is loaded with adherent residues, for example, pitch vapors, a device is provided with which, during a purification mode, at least a portion of the clean air can be optionally fed past a section of the heat exchanger located closer to the combustion chamber and into another section of the heat exchanger located further from the combustion chamber. Deposits, which have formed in the vicinity of the cold end of the heat exchanger, can be removed in this manner, particularly oxidized.
