WE HAVE 05 NOS. OF BHEL MAKE Heat recovery steam generator. Since last 2 years we have problem of Scanner failure/ damaged. We also faced problem coke dust carry over and disturbe scanner view and flame failure. Coke fourmulation near to scanner tip also one of major issue. What are the probable reason for above problem ?
(1) Scanner failure/damage
(2) Coke formulation on tip of scanner
(3) Dust carry over.
We have scanner cooling air fan which supplied cooling air to scanner with a pressre of @300mmwc. We have 'ICAN' make scanner. Air pressure is sufficent to cool the scanner or not ?
