Abstract

In a control loop for regulating a combustion process in a plant (e.g., a power-generating plant, a waste incineration plant or a cement works) having a controlled system for converting material by way of the combustion process while supplying air, with at least one flame body being formed, and having at least one observation device for imaging the flame body, other sensors for determining the input data, at least one adjustment device that can be controlled by output data for supplying at least material and/or air, and a computer for evaluating the input data in relation to target values and for determining the output data by using a current process model, the computer has a feature extraction module that extracts features from the input data using an information measure. The features are informative for the target values, and are for use in an alternative process model.
