Solar gasification of charcoal, wood and paper

Charcoal, wood and paper have been gasified in a 2 kW solar furnace by injecting water directly on the hot fuel. In the case of charcoal, approximately 30% of the incident solar energy was stored as chemical energy and 55% of the injected water was consumed. Wood and paper gasification can be explained by conventional pyrolysis followed by the gasification of the charcoal formed.
