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.

Method for characterizing the exhaust gas burn-off quality in combustion systems

In an apparatus and method for optimizing the exhaust gas burnout in combustion plants having a solid bed combustion zone and an exhaust gas burnout zone wherein oxygen-containing gas is injected into the exhaust gas flow in the burnout zone by way of a plurality of secondary gas injection nozzles, wherein each injection nozzle is provided with a control valve, means are provided for determining the presence of incompletely burned exhaust gas components in the exhaust gas burn out zone and a control unit converts the signals into control signals by which the valves or group of valves are individually controlled so as to inject oxygen containing gas into the exhaust gas flow in order to concentrate the injection of the oxygen containing secondary gas into the areas in which incompletely burned exhaust gas components are present.
