Advanced Combustion Control (ACC) can be used to provide state-of-the-art advanced control of the combustion process. It delivers optimal thermal efficiency through tight dynamic coordination of the fuel flow with control of the individual air channels. Emission limits are observed, the boiler combustion process is stabilized, and heat loss in flue gas is minimized.
