Another test of the wood gasifier was performed today. The results were completely different to yesterday. The hole at the top of the cowling was widened and the fuel had wood chips added on top instead of cloth.
Almost immediately wood gas was generated. It was ignited intermittently and created small explosions that almost blew the flame out. It was like listening to a steam engine leaving a station with the sound of the steam slowly puffing. Five minutes later a larger explosion blew the cover off the top. The top was replaced. After 10 minutes the flame went out and a lot of smoke billowed out until the fuel had been consumed.
Tomorrow, wood chips will be used instead of pellets and the primary air holes will be made larger.
