Thread: Concentric Exhaust Steam Pipe

    Default Concentric Exhaust Steam Pipe

    I see in a few members profiles that they are using the Concentric exhaust. I have wondered how they are working for you and does it control the sparks for the guys burning wood. I know two producers that I visit on a regular basis when their in the heat of the battle. I generally look for the steam during the day or the sparks shooting skyward during the night. The one guy has set his area around the sap shack on fire more than once from the amount of sparks he can get billowing out of his rig.

    Does the steam have much of an effect on them?

    Mine has worked well for me. As far a sparks, I did not have any come out this year. Last year with the AUF turned up more I did have some escape but you can extend the outer stack more to give the sparks more time in the steam before they exit.

    I don't get sparks out the stack and I don't have a concentric exhaust system. I did get sparks before AOF. Either add AOF or get the concentric and you will be safer. Fire outside the arch is not good.
