<x-charset ISO-8859-1>The quick answer is no. Glycerin is a very viscous liquid, and the solidification point varies with the soap in it, the residual alcohol, and the completeness of the reaction. It is sometimes solid at 65 degrees F. What's more, it is dirty until it is at least partially refined. If there is no methanol recovery, it will have a volatile component and a refractive component. Glycerin flash point is over 800 degrees, and a waste oil burner will burn the volatile part, but not the refractive part, which will quickly gum up the works.
If glycerin is burned without enough air it may form a poisonous acroline compound. If you look at the structure of a glycerin molecule you will see three carbon-oxygen double bonds, which are hard to break and take a lot of energy input. Carbon-oxygen double bonds are effectively carbon monoxide, meaning that the molecule is effectively partially burned already, and has a relatively low heat value per pound. A good glycerin burner handles a semi solid well, or preheats until it is a liquid. It has a fire starter of some other fuel, hopefully biodiesel or WVO, to get it up to temperature so the glycerin will burn. Then it has enough insulation to maintain this temperature, or at least has minimal heat withdrawal so the fire is not extinguished. It also has adequate air for clean combustion. I had to build this system because no standard burner does these things well. It is a masonry heater with a babington burner for a fire starter, burning WVO, and a secondary fuel feed for the glycerin. There are no visible emissions, and I hope that indicates a clean burn.
