Abstract:
A method for metering a quantity of a reducing agent introduced into an exhaust-gas or exhaust-air stream of a combustion installation, which comprises:introducing a quantity of reducing agent into at least one of an exhaust-gas and an exhaust-air stream, setting the quantity of the reducing agent by using a functional relationship based on operation-relevant parameters of at least two of a combustion installation, an exhaust gas and a pollution reducing catalytic converter;adapting the functional relationship to a current state of the pollution reducing catalytic converter;checking the functional relationship during operation of the combustion installation; andadapting the functional relationship to a current operating condition of the combustion installation and to a current state of the combustion installation as the functional relationship is also modified with respect to the operational parameters of the combustion installation.
