I think you will find on reflection, that the the firebox situation is totally different to a packed bed open core stove or gasifier. Without doubt fuels are always better dry than wet, but the rate of SV (I can remember you were very hot on SV at one time) at the oxidation raw fuel interface, in relation to the open core diameter, assists to maintain a stable flame front. In a TLUD, this would probably only be a distance of a couple or three pellet diameters to consume the pyrolytic gasses leaving the charcoal behind, due to the air entering the bottom, and the flame front heading South as fast as the SV allows. Within the normal commercial range of bagged pellet’s MC, one might think that this at least, would allow very specific performance to be expected from any given size of core diameters. > It seems counterintuitive to think wood can be TOO DRY, but this is at > least one case.... I agree, buy only as applied to a firebox situation. > TOM REED (on his new CHROME laptop)... Well at least we can still enjoy new "things", I just bought my first ever heat gun, lots of grunt, 2,000W (:-) Doug Williams, Fluidyne. _______________________________________________ Gasification mailing list to Send a Message to the list, use the email address [email protected] to UNSUBSCRIBE or Change your List Settings use the web page http://lists.bioenergylists.org/mailman/listinfo/gasification_lists.bioenergylists.org for more Gasifiers, News and Information see our web site: http://gasifiers.bioenergylists.org/
