Method of controlling a combustion flame and a microphonic probe allowing the application of the method

摘要

This invention relates to combustion control. It preferably uses a microphonic probe. Within a water circulation enclosure, a probe head defines a thin channel joining a cavity to a furnace, the cavity being closed by a diaphragm arranged as an acoustic transducer. The acoustic pressure which is detected is connected to the combustion characteristics. The invention is used in particular for turbulent premixture flames.
