Vision Tech for Counter Tech

I contructed what should be a diy gasifying wood stove, following a paper written at The Biomass Energy Foundation in Goler, CO. The pictures below are from our first attempt at replicating their results. The paper only gives very cursory instructions on how to build and operate such a stove from 2lb coffee cans. The point of this is that if it burns correctly, the stove will be burning wood but have very low emissions, so low in fact that burning wood inside does not require ventilation. Obviously that also means it’s very efficient. Our first attempt worked fairly well. Though we didn’t get a totally blue flame, we did see the smoke disappear, which means the fire was burning cleanly. We did see some blue flames deep in the fire and additionally noted that the fire smelled different than normal.

Getting the fire started, without it’s top (gas wick) on yet.

Next time we will be experimenting with changing the size of the gas wick and allowing more airflow into the burner.
