B
frame-V gas turbine, running in NG fuel with HSD stand by. there is HRSg also with supplementary firing on need basis (on average daily 3-4 hrs). The flame detection signal L28FDA is bypassed/forced.
my question is
1. what may happen if actual flame gets out?
2. what may be the worst effect before turbine tripped in secondary protection like reverse power?
3. My another question is, say when there is supplementary firing ON in HRSG side and actual flame gets out, and NG gets into turbine and exhaust path without burnt. When released NG reaches supplementary firing flame area, flame will come back up to turbine blades and explosion may occur. Am I thinking realistic?
may please be enlightened.
