Title:
SYSTEM AND METHOD FOR DETECTING PRECURSORS TO CONTROL BLOWOUT IN COMBUSTION SYSTEMS
Document Type and Number:
WIPO Patent Application WO/2015/068176
Kind Code:
A3
Abstract:
A method and system for determining one or more precursors to control blowout in a combustor is provided. The method includes obtaining a time series signal corresponding to a dynamic state variable of the combustor. The method includes detecting one or more precursor based on an analysis of the time series signal using one or more parameters to control blowout in the combustor. One or more parameters include a Hurst exponent estimation, a Burst count estimation, and a recurrence quantification based estimation.
