[Stoves] Very small stoves and reheating food

[Legacy Mail]

paul just a few days ago someone was showing ahopper full of logs : You responded th Crispins comments about a tapered hopper for presimably feeding chips into the stove.   Is it so hard to conceive of a tall vertical feed tube with a slow bend into the combustion chamber, sealing the open end to prevent air feed as well-- to prevent turn, back burn up that tube

>> Definitely scalable. It is likely to be the same as the diameter of the chamber small stoves, not on top.  Note that a 5 inch stove is pretty small if it is Jiko or POCA-like.

>>  
>> Yes quite different. Different principle and not as effective, and disturbs the fire, and                       the heating of the ‘charge’ does not assist drying the charcoal below. The cone is much more effective. Try it and you may introduce it as an accelerator for the TLUD pellet burners.

>> Incidentally we ran a stove I found in TLUD mode today using kinda long 8mm pellets (local wood) – breathed rather too much but apart from being a biggish flame, ran CO/CO2 at <0.60% for ages (certainly more than an hour) and ≈0.30 quite a lot of the time. There is a lot to be said for the combination.  I will try a new TLUD pellet stove tomorrow.
