Pyrolysis and gasification characteristics of wood were analyzed for a small-scale high-efficiency co-production system. Wood was easily pyrolized to yield combustable solid(char), liquid and gases at about 500℃ within about 10 minutes. In this system, using the pyrolysis gas as a heat source for the reaction makes the system simple. However, this is not feasible for wood of high moisture content because the heat required to dry the wood decreases the net amount of products. For the gasification system, there found a suitable reaction temperature and an air/fuel ratio to maximize the cold gas efficiency. Using the pre-heated air is an effective way to increase the efficiency. An electric power efficiency near 24% can be obtained by heating the air with the hot flue gas from the gas engine.
