Abstract
A method and device for monitoring combustible matter in a hot gaseous stream and generating a control signal, a controlled jet of an oxidant is injected into the gaseous stream with a lance extending between a window of a monitoring device and the flow path of the gaseous stream, the lance defining a line of sight between the window and the gaseous stream in the flow path, the combustible matter burns with the oxidant in a flame in the gaseous stream in front of the lance, one or more properties of the flame which are correlated with the concentration of combustible matter in the gaseous stream are detected by the monitoring device through the line of sight and the window and the monitoring device processes the one or more detected flame properties and generates a control signal on the basis of the one or more detected flame properties.
