This disk covers about 64% of the pyrolysis surface (15 cm in diameter). An interesting result is that this clearly creates two very distinct chambers in the system. One below the disk and a second between the disk the cap. The bottom chamber is the pyrolysis chamber. The upper chamber is functionally a combustion chamber. This is made clear by the fact that the pyrolysis in the lower chamber will NOT ignite the gases in the combustion chamber. These gases must be lit by a second ignition process. The pyrolytic gases will “smoke” until the fuel air mix is rich enough to sustain combustion in the upper chamber.<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>I am still working on an ignition system for the top chamber. The pyrolysis in the lower chamber is easily started with wood pellets soaked for 5 minutes in 90% rubbing alcohol. The cross over to combustion of the gases in the upper chamber happens around 10 minutes into the process. At this point, I carefully squirt some gelled alcohol on top of the cap. It immediately starts to vaporize. This creates an explosive mix in the draft can which is very easily lit — but must be done from the edges to avoid a flash burn when the alcohol gases ignite explosively. I usually have to repeat this process two or three times until the fuel/secondary air mix is rich enough to sustain combustion. Then it is off to the races.<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>Comments? Suggestions?
