Claim Text:
1. Thermal afterburning system comprising: a) a combustion chamber, which comprises b) a supply line, via which the burner is feedable with a burnable gas; c) a gas regulating valve in the supply line; d) an outlet line, via which the clean gas is dischargeable; e) a control device which controls the gas regulating valve for setting a desired temperature in the combustion space; wherein f) in the outlet line there is provided a carbon monoxide sensor which generates an output signal representative of a carbon monoxide content of the clean gas and feedable to the control device; g) in the control device there is storable a target value for the carbon monoxide content of the clean air; h) the control device being programmed such that in the event of a deviation of an actual value measured by the carbon monoxide sensor from the target value of the carbon monoxide content of the clean air, the gas regulating valve is adjusted such that in the combustion space of the combustion chamber a temperature is set at which the actual value corresponds to the target value, the system further comprising a pollutant sensor which measures a load of the pollutant-containing exhaust air, and in the event of a change of the load, modifies the target value stored in the control device and/or the output signal delivered by the carbon monoxide sensor such that the temperature in the combustion space of the combustion chamber is changed in advance in a direction which is required to maintain the target value of the carbon monoxide content in the clean gas.
