Redesign for air inlet duck

Redesign for air inlet duck

Redesign for air inlet duck

(OP)
We have a GE Frame 6. It used to air filter  frontside filter type of G3 and back side filter type of MF090 (frame type). We do not  want to loosed time  when changing the air filters. Gas turbine will not stop when we changing filters. Actually think that  redesign for gas turbine air inlet duck. Maybe it  can be duble duck front the compressor. While  the air intake  through first duck another duck will be closed. So gas turbine do not stop,

Is it  possible? How can we do?
 
Please guide me.
Thanks.

RE: Redesign for air inlet duck

Hi,


Yes, I think its possible.

Be very careful with your new design because you must take into consideration if you have enough available space for the new duct and if this one will not introduce turbulences in the new inlet duct or in the old one (considering the changes that you need to make into the existing project).

A modification can improve (or decrease) the quality of the compressor/gas turbine running, depending on your design solutions.

Your proposal is used (for example) in oil systems, as a by-pass filter, in order to not loose the time when you need to change the filters (at those gas turbines which need frequently changing of the filters). The same system can be adopted in your case but, once again, be very careful with the new design.

You must have the same air flow and if its possible, the same conditions at the compressor intake (air speed, a.s.o.)

Another aspect of the problem is: speaking from the economic point of view, this solution is good for you?

I think there will be a lot of costs with the new design, modifications, fabrication, interupting the function of the gas turbine....

Regards
Fernando

Have you thought about looking at a different type of inlet duct. Donaldson makes a duct that that has external filters that can be changed on the fly.
