For this ABB model, it doesn't have any drain lines, and its operation - maintenance manual is not mentioned any drain lines. Yes, there are some model turbochargers that have drain lines that must be checked for the accumulation of carbon deposits that could clog the drain.
Hi. After waterwashing the turbine side of the generator the exhaust inlet temperature going to turbocharger become higher and now the turbocharger is whistling. I followed the same procedure since it's also Yanmar and it has same instruction in the manual. Should I waterwash again or could it get worse?
@@D-solut you could do it again. If things get worse better to check the turbocharger by opening up. Discuss it with your chief engineer for proper disassembly procedure.
1.should the turbocharger switched off if it needs to do this process? 2.if the tc switched off, also the engine too right ? or just tc ? 3.your experience its so meanfull, thanks !
@@ayandamkhize860 The turbine is a power developing device. As the high pressure exhaust is directed on the blades, it's kinetic energy is converted into the rotation of turbine blades by providing a thrust to them, this leads to drop in pressure and temperature. ... then as the pressure decreases the temperature decreases.
What about drain line? Abb usually have it and before turbine cleaning need to check if it clean.

Is the generator in service or connect? Or disconnect in bus while doing turbine wash?
Its already connected and partially serviced at 20% to 40% load.

Turbo Charger washing in the process is needed to be in operation.
unless turbocharger is for overhaul the engine must be shut down and cooled down.
@@balanayharry thanks man, and whats the material for turbine washing ?

Why is the turbocharger exhaust temperature after turbo lower than temperature before turbo when the engine is running on load.
