Current optimization of power boilers is a very important issue in research and implementation, particularly in the context of increasing environmental requirements. Combustion process requires control large number of process variables, which is usually implemented by means of the classical single-input PI or PID controllers. A large inertia and non-linearity of the combustion process necessitated the searching for new solutions in the field of control, which except better control also will allow for boiler operation optimization due to new ecological and economic conditions. The article presents the results of work of the immune optimizer SILO II installed in a distributed control system (DCS) of 650 t/h live steam power boiler. Preliminary identification tests involving the control of the amount of over-fire air, showed a strong correlation between the OFA nozzle opening level and the shape of the flame (flue gas temperature distribution). Identified relationship was basis for inference of the possibility of flame shape control to obtain optimal combustion conditions in terms of gas pollutants emission and improving the thermal efficiency of the boiler.
