Abstract
A method for detecting flashback events in gas turbine is disclosed. The method employs periodic reference point checks to determine whether or not flashback damage has occurred. The method relies on the repeatability of exhaust profile and NOx as functions of precise turbine conditions. In combination with experience-based limits, changes in these values are used to determine if a flashback has occurred, even days later.
