One of the best kept secrets seems to be the author and title of this much discussed thesis. Can anyone enlighten me? Peter Sent from my BlackBerry 10 smartphone.
Paul etal: I should have added there are some good discussions of the same stove/cylinder (glass) with numerous types of fuels. And he shows they obey the same laws - can predict performance (front velocity, power level (?) - given the superficial velocty.)

Paul: I know very little on the Oorja stove. But the thesis is mostly (entirely?) on a packed bed, top lit. It is on the migratory pyrolytic front (MPF) - so should be applicable to all TLUDs. I would like to hear from any/all on whether I am getting the right reading about NOT consuming the char.

Ron,
I am in Uganda now and have not had a chance to see the thesis. Thank you for the comments. About #3, the Oorja stove is rather heavy for turning over, has a smallish fuel chamber meaning not much char and only short TLUD burns, and has a loose cast iron cup in the bottom that would fall out if the unit is tipped over to remove the char. It is designed to NOT be tipped over for saving char. It is intentionally designed to have continuous burning with the fire in the bottom consuming char. And when doing that, the Oorja is NOT operating in the TLUD mode which is specifically characterized by the migratory pyrolytic front (MPF), but the Oorja is not with MPF after the rather small initial load of fuel has been pyrolyzed. Therefore, the Oorja (and most others with forced air FA) essentially is NOT a TLUD because it is operated without the MPF except for the initial batch of fuel. I will be addressing this topic more at the Stove Camp at Aprovecho on 22 - 26 July. Paul Paul S.
