hi,
In my company we have DLN type GE FRAME 9E MARK V. when trying go to premix mode the flame detection trouble & failure to flame out in primary Zone alarms are appear. after that the alarm relay is active and the extended lean lean mode is appear. after that we check the intensity of flame for primary zone:
flame # 1: 92
flame # 2: 124
flame # 3: 82
flame # 4: 0
the setting flame detector for premix mode steady state is 64 cont., but during the transient mode is 128 cont. we decide to force the signal of L28FD_PRI_HI. it's means when the premix mode steady state is appear the intensity of flame detector be at 128 cont.
please help me, if we force the intensity of flame from 64 cont. to 128 cont. what happen for combustion chamber?
in my document said when the flame detector operation the intensity increased then you can reduced the intensity of flame detector, but we don't know how much?
I don't know the different intensity of flame detector from 64 cont. to 128 cont. I think two value are very small for detection of flame in primary zone when working in premix mode.
