What's my Burner exhaust temp?

[dieseldad97]

I need a chimney for my PP 8gpm skid and was asked today what the temp was coming out of the burner. I need to know what guage steel to use when building/fabbing one up. I told the guy I had flames coming out at times lol. Any ideas? Thanks.

I've never measured exhaust temps, so I can only say frickin hot. If you use a collector over the stack, it will draw in cool air as the heated air rises out of the stack. I use double walled gas flue http://www.hartandcooley.com/Products/venting/b-vent/hart-and-cooley-type-b-gas-vent.aspx to build a chimney as long as I'm getting make up air. If you're attaching the flue solidly to the machine, you'll need pipe rated for oil or wood http://www.hartandcooley.com/Products/venting/chimney/tlc-5-to-8-inch.aspx .

Depending on the size of the motor, between 500 and 1000 degrees.

I have used a single wall pipe in the past and it works ok but it will have a tendency to breakdown and needs to be replaced every once in a while. I agree with Russ, if you want to avoid potential burn issues go with a 'b' vent. The double wall will keep the outer housing much cooler than the single wall. You can pick it up at fireplace stores or heating supply companies. Some home improvement stores will carry it but it is tough to find an 8-10" pipe there.
