I do not know how big your engine is but here is a 855 cummins on a 300kw Onan genset. Think it is 6" off the turbo and bumps up to an 8". Don't think you can run with these measurement I don't know what you have. Talk to manufacturer or dealer. The muffler is mounted on the ceiling and exits out the side of building. It is all heavily fiberglass insulated. Since this generator is on an exterior wall you can see the fresh air intake and radiator are right there close. Sometimes fresh air must be piped to the intake and sometimes radiators are mounted remotely outside. Sizing of the exhust is important so you do not harm your engine. Ring those phones and read those books!
The outlet size of gen is 8" and we will use 12" pipe connected to it. And the pipe will directly run outside the room above false ceiling to discharge the exhaust air to atmosphere.
Tha gen is perhaps 500kw. I just want to confirm if we need any fan to pull exhaust or the exhaust will itself carry out. As the exhaust is 118cu.m/min which is high and pipe size being small, the velocity will be enough to clear 13m distance.
What engine? I am assuming it is turbocharged. Make sure to have vibration isolation like in the picture. Well insulated pipe will help the exhaust scavenge also. You need to make some calls about the exhaust sizing. Also the mufflers used for this if you are using one are not something like on a tractor.
What if pictured is probably 40' worth of pipe and the turbocharger on this one does well enough to push the exhaust. You need to talk to your dealer or the engines tech support. DO NOT TAKE MY WORD for it. I am just trying to show you how typically the exhaust is ran. That is a high dollar machine and the plumbing is not cheap either. Do it right the first time so you don't royally screw up.
Its actually a perkins diesel generator.
Can you just say about the pipe material and specs to be considered as per your assumtion and experience. Just for an idea. (will however confirm with the mnfrer.)
I am not the guy to size it for you. I do not have enough experience in that department. I turn wrenches on big diesels as a hobby. Just trying to help you out since the facility I was at had a typical indoor setup that I could take pictures of. I would like to also learn about this and further assist you. Any more info on your generator you could give me would be helpful for me to help you. I honestly have never heard of an additional fan in this application. Proper sizing and the turbo should blow it right out I would think.
Here in the USA... one MUST install things according to manufacturer's specifications... or deal with the liability of what happens if they do not. There is a reason for this:
Lets say this flue pipe (exhaust pipe) is installed incorrectly (does not matter how, just that it is not installed to the manufacturer's specifications... THAT is the ONLY thing that matters). Now lets say a fire is started and someone (or lots of folks) get injured or killed. Who is gonna be liable?
Bottom line it is a simple (and legally binding) decision:
If the pipe was installed to the manufacturer's specifications... then the manufacturer is liable... however:
If it is installed ANY other way (regardless of what the way or what the reason)... then whomever was associated with deciding how to do it and/or who did it... is liable...
Now I do not want to bust your b*lls... however do YOU want to be liable... or would you rather the manufacturer be liable? Simple, right? :)
Here in the USA, this legal system keeps folks honest and stops folks from being 'cheap'... :)
The problem with our system in the USA is... the lawyers make WAAAY too much $$$ in a court of law deciding what the facts are; whether it was done to manufacturer's specs or something else. Us Americans REALLY NEED to address these prima-donna's (spoiled children with attitudes in adult bodies) called lawyers. :)
Thank you all for your valuable time n response
Your welcome hope it was some assistance. Good luck!
