I've been doing several postings on that other web site on this topic, so here is my input on this topic. The Babington burner works great for raw oil, ugly biodiesel, or other fluids, but it will not burn glycerol in concentrations greater than about 20 or 25%. It seems that this stuff is water based and just doesn't have all of the energy needed to sustain a flame. I had considerable success last winter in burning it on a wood fire, but by itself it would only burn the volatile part and then leave a substantial vegetable gum residue that did not burn.
My current plan is to build a masonry burner that maintains the 1000 degree temperature needed for complete combusion. The Babington will keep up the temperature using raw oil and the glycerine will be dribbled into a pan where it should burn cleanly, leaving a mild residue ash. All of this is theory, but I have hope this system will work after 2 years of efforts. Tom Leue @ Homestead Inc.

Hello David No takers here, no, unfortunately (circumstances forbid), but a very interested bystander hoping you'll get takers elsewhere. I'm glad you're taking this on, please keep us posted.
