Diesel Engine Dyno Exhaust
Diesel Engine Dyno Exhaust
(OP)
Can anyone tell me what codes govern the venting of a diesel engine dynomometer? The engines being tested will be directly connected (no dilution air) to this exhaust stack. Temperatures can be as high as 900C. The vent will have to go through a block wall to the outside, and up the side of the building to some distance above the roof line.
My plan was to use schedule 10S type 304 stainless pipe, directed upward with no stack cap (to get the plume away from building intakes). I'm trying to decide whether or not to insulate the line once it leaves the building, and I would like to see if I'm missing anything else.

RE: Diesel Engine Dyno Exhaust
You might want to put a baffle between pipe and building to mitigate radiated heat, but I don't see an upside to insulating the pipe except where it passes through conditioned spaces.
Additionally, 900C is not credible for Diesel exhaust. 900F ... 1000F is.
If you don't put a cap on the stack, you'd better put a dead leg with drain at the bottom to catch rainwater and keep it out of the engines.
