Diesel Generator Exhaust Piping
Diesel Generator Exhaust Piping
(OP)
We need to pipe an indoor generator's exhaust about 20 ft or so to the outside wall of a building. So far I have specified welded stainless steel piping but is there any reason I couldn't use Schedule 40 black?
By the way, I have also specified two layers of 1-1/2" calcium silicate insulation per a John's Manville guide.
Thanks in advance.

RE: Diesel Generator Exhaust Piping
Cummins allows black iron Sched 40 on their systems - so it's probably ok. But, I'd check w/the manufacturer of your gen set to verify.

RE: Diesel Generator Exhaust Piping
Exhaust gas is quite corrosive to plain carbon steel.
A lot depends on how this gen set is used. Intermittent use will corrode faster.
A hole in an inside exhaust can kill people.
For 20ft of pipe why take the risk?

If you can find a coating that would tolerate the temperature.

There are field-applied products that under good conditions can achieve a continuous film for at least "a while".
I don't know if any of them would survive exhaust temperatures.
I would not bet against your cost and reliability guess.

As stated above, what does the engine vendor suggest ? .... The additional cost of a 10S SS system is modest and will probably have a mich longer service life than a black CS pipe

--------------------------------------
If it was a gasoline engine you would be correct.
Diesel engines have been used in underground mines long before anyone was worried about emissions.
Gasoline engines produce a lot of Co, Diesel engines not so much, though I would tend to think
the ones that use EGR would produce more than the older ones of years past.
The smart thing would be to always vent a room that is to contain an engine.
RE: Diesel Generator Exhaust Piping
If the room was constantly ventilated then it might be acceptable. But for the cost why bother.
