Well no, when the burn has made its way all the way to the bottom a tlud becomes a charcoal brazier, If you want to argue semantics. I didn’t think we were into that around here. My water heater tlud was not imagined to be a char gasifier. And though it would probably work for a short time there are much better, simple char gasifiers to be found on this site. I made one based on @k_vanlooken’s [Some School In Thailand](http://forum.driveonwood.com/t/some-school-in-thailand/4372) thread. It will supply gas to my [3KW genset](http://forum.driveonwood.com/t/charcoal-gasifier-for-generator/2379/495) for about a half hour. I take the charcoal I made in the tlud and put it in there. There needs to be ~24 inches of charcoal above the nozzle to make good gas. I plan to make a new one with a larger diameter and a 5 gallon hopper above the 9 inch diameter 24 inch long pipe. I plan to insulate the inside of the pipe with an inch thick ceramic wool blanket. I hope this rig will give me two and a half hours runtime.
