We were having issues with Exhaust Mass Gas Flow. It was traced to 96BD-1 (Compressor Bellmouth Differential). The low side process line is clogged. We found about a pint of black water wash liquid in the tubing. It was drained at the low point of the tubing where it inserts at the bellmouth housing (turbine compartment side). Removing the liquid did not unclog the process line. There are six taps for the tubing. It encircles the bellmouth housing.
We have a GE frame 7FA combustion turbine. I have researched all drawings available to find out where the path of inlet flow enters the bellmouth and exits to the tubing taps. We entered the bellmouth area looking for the obvious. The IGVs were closed and we were on gear so our look was limited. Without knowing the path I am not confident to pressurize the taps to clear out the clog.
Any information on this matter is greatly appreciated!
