One of my options would be to recycle it back into fireball production.

A good fitting cap solved this for me. Tin can and mud sill. Install after
shut down.

Easyer to cool gas.

Less water in gas (see above)

Tar destruction before the gasifier. Kind of like a two stage gasifier.

About double the miles/lbs.

Can be densified.

Smaller lighter rig.



Great job!
