Hi All, We are currently running a frame 9e dual fuel gas turbine (as originally designed) with diesel fuel only. Although the turbine is designed for both gas fuel and diesel operation, it has never run in gas fuel due to unavailability of gas. Currently we are looking forward to receiving gas...

Hi All, We are operating 2 frame 6b gas turbines manufactured in 1987 and I have few questions around compartment ventilation system. Any information would be highly appreciated. 01. There is a ventilation fan mounted in-between accessary compartment to Turbine compartment (88BT). Does the...

Dear All, We are looking forwards to buy MHI 701D combustion parts, consumables and some refurbishment work. Dealing with MHI Japan had been very slow process. Any suggestion of prospective service providers/part suppliers that you would have used would be really appreciated.

Dear All, We have couple of Frame 9E peaking units with Donaldson Spider web Conical and cylindrical Filters + pulse cleaning system installed. I would like to seek information and experience on expected filter life. The filter DP does not go high due to less dusty environment hence the...

Hi, I am looking forward to see any a P&ID or a schematic that shows the valve position of Low lube oil header switch and transmitter arrangement. see the attached picture of how it looks like. I am particularly after the position of porting valves. should both of them be closed during normal...
