Abstract (en)
[origin: WO2014075795A1] The invention relaters to a method and device for improving combustion in a combustion chamber (1) with a plurality of burners (2), wherein at least a part of a fuel and/or air mass flow (ṁB , ṁL ) can be adjusted for at least one section. A local distribution (VR) of a parameter (λ, T)characterizing the quality of combustion is determined by measurement in an ignition/firing region (ZA). Based on this, at least one region (G1-G4) with an unfavourable parameter in respect of combustion quality is identified. A section of the combustion chamber essential for a flow, pyrolysis and combustion simulation is mapped in a digital simulation model (CDF), divided into a plurality of volume elements (dV). The origin of the fuel and air components (AB/ AL) coming from the various burners is continuously and separately taken into consideration in the simulation of each of the volume elements. A distribution (Vs) of the fuel and air components corresponding in location in the simulation model to the local distribution determined by measurement is defined. At least the one burner critical for each region identified in respect of the fuel and air components recorded is determined to improve combustion by a correction of the relevant fuel and/or air mass flow.
