I'm frequently experiencing failure to start the Gas Turbine on distillate fuel. It is mainly caused by the starting atomizing air booster compressor to be seized. After inspection of the compressor, we found out that there is water found in the pipings and has caused the compressor to jam (oil has turned into emulsion). My initial thought that It could be due to frequent online water wash that we usually do to increase the load during high temperature during the day.
My starting atomizing air booster compressor will always seize from operating because of the water that entered the atomizing air pipings has caused the compressor to jam. (is this valid?)
If so, how am i able to avoid such occurrence to happen again? As i know all the water wash provision valves have to be opened during normal operations. So is there any problems why the water wash liquid is able to enter the atomizing air line?
