Hi,
i am a shift engineer of a FR9E gas turbine-simple cycle. I've been asked to write an article to get promoted and i was thinking to write about how to eliminate flame scanners and replace the controlling to be with just exhaust thermocouples.
i need help to set the guidelines for my article. can we set some rung to come with the result of (flame established) by using the temperature change in exhaust thermocouples during firing time?
i was thinking of delta temp. versus time but i need values to be true and practical.
what about flame out (or fail to ignite)? is it possible to be controlled without flame scanners? how? combustion monitoring is already done by logic and no need to manipulate any rung (i guess) so, what i actually need is a complete picture of flame approval/ flame out without using flame scanners.
