Abstract

A method for characterizing a flue gas burnout quality of a combustion process in a combustion system having a gas burnout zone includes optically detecting in a visible wavelength range, in a flow cross section of the gas burnout zone, low-soot combustion regions, regions without combustion, and sooting regions, so as to provide a plurality of successive individual images, the regions without combustion and the sooting regions having different dynamics. The plurality of successive individual images are analyzed so as to distinguish regions of transition, to the low-soot combustion regions, of the regions without combustion and the sooting regions.
