Dears,

We have 3 Frame-6B and 2 Frame-9E GE machines. In Fr-6B all compartments were equipped with fire protection system like fire detector and Co2 lines.

In Fr-9E after turbine compartment there is no fire protection system. What is the reason GE didn't provide fire detector and Co2 lines in the coupling and exciter compartment? (they may have some valuable reason)

Both frame is not having damper closing feedback. How far it'll be useful if provide limit switch or any other feedback instruments?

take care

Umm, there's like this big source of fuel in the Frame 6B Load Compartment, called the Load (Reduction) Gear. And a lot of high temperature metal (the back end of the exhaust). Combine an oil leak from the Load Gear (happens when people ignore increasing or high Load Gear vibrations for extended periods of time, which a lot sites do, letting the vibration get high enough to trip the turbine before taking any action, or worse, defeating the trip--both happen fairly frequently, actually), and it's a recipe for fire.

There are Frame 9Es with fire protection in both the Load Compartment and the Collector Compartment. It can be provided for a fee (purchased option), or when the local fire codes or the machine's insurance company require it.

Don't understand the "question" about damper switches. Don't understand the problem you're trying to solve. More explanation and some more details would help.

 

Ok understood, since there is no insurance requirement we may not go for fire protection system in the load and exciter compartment.

About the damper feedback you and Mr.Pascal already had explained (i didn't check your replies due to maintenance activity, sorry). the link is below,
