Clogging Of Burner Nozzles
Clogging Of Burner Nozzles
(OP)
Dear All
The nozzels of fuel gas burners in our gas turbine have been clogged due to ingress unclean fuel gas flow through them. It seems the gas line was not enough clean and was including some particles and sands. Now, the manufacture company is commenting to remove all the burners out and clean them. This is very difficult to do for us at the bieng time because of project schedule and we are looking for a procedure that can clean the burners without take them out. we already have accomplished the reverse blow out via the cumbostion chamber pressure in full speed no load which was creating a pressure about 12 bars. It could help just little.Any comment would be appreciated.

Sounds like you just answered you flame instability issue. Your fuel nozzles need to be clean, especially in DLN systems.

What sort of gas turbine is this? How do you achieve reverse blow out (and what is reverse blow out?) - are you surging the compressor section?
How often do you have to change out the burners and what are the indicators that a change is required? If your engine is fitted with more than one exhaust gas thermocouple, have you tried plotting each individual thermcouple reading on a 'radar' plot and looking for changes in the profile in order to detect burner problems at an early stage?
Can you get a spare set of burners and carry out a replacement each time the turbine is down for a crank wash?
