Cord wood gasification and combustion.
ABSTRACT A1.0 GJ/h cord wood gasifier-combustor was designed and tested. Two-staged combustion of cord wood up to a diameter of 15 cm was achieved with a net energy efficiency of 70 to 80 percent. Exhaust which was low in carbon was emitted when the C02 content of the exhaust was below 15 percent. Modulation of the system output was demonstrated. The major operational problem encountered was batch loading of wood into the hot gasifier.
