Dear Stoves/gasification The TLUD stoves is unique in NOT burning the charcoal as it gasifies only the cellulose, leaving charcoal behind. However, the charcoal is a buffer against using wet fuel. The PYROLYTIC gasification of the cellulose portion can't proceed in the next layer until the fuel is dry. So, some of the charcoal is burned to dry the next layer if the fuel is moist.
Alex English and I tested this by adding water to bags of dried chips to make 0,5,...30% moisture test fuelsand burned them in the WoodGas stove. The bone dry chips produced 25% charcoal, and the 30% moisture chips produced only 3% charcoal with a very blue flame because the charcoal was mostly consumed to ignite the wet next layer. So the WoodGas stove has more tolerance for moist fuel than other stoves due to the production of charcoal during gasification of the cellulose. Onward! Tom Reed in Cudjoes Key, FL.
