can you tell what fuel you are using ?
we face the same problem.
please contact me.

: We are facing problem of difference of more than 100 deg centigrade in two thermocouples located in GT exhaust. Details are as follows
: (i) Temperature in all six thermocouples is as (in deg centigrade)
: CT102B=503,
: CT103B=578,
: CT104B=611,
: CT106B=578 ,
: CT107B=593
: CT108B=549.

: CT102,103abd 104 represent left hand combustion chamber and CT 106,107and 108 represent right hand side combustion chamber .

: (ii) All the thermocouples are calibrated and checked for terminal tightness and mv values. And found OK
: (iii) Machine had clocked 37000 EOH
: (iv) All flames looks OK


: We are planning to inspect the burners for any clogging, erosion or damage.
: It will be great help to us if you can, please, share your experience of this.
