Abstract

The invention relates to a method (and corresponding soft sensor) for determining one or more cement kiln process parameters, the method comprising the steps of collecting at least one process measurement representing at least one process parameter and collecting at least one item of image data representing a burning zone; wherein the method further comprises the step of performing partial least squares regression on said collected at least one process measurement and said collected at least one item of image data to calculate a soft sensor output. Hereby is achieved, among other things, the determination of difficult accessible cement kiln process parameters.
