Abstract
In order to clarify the thermal decomposition behavior of urethane RDF (Refuse Derived Fuel) and wood chips, the pyrolysis experiments were performed under two isothermal conditions, which are 500℃ and 600℃ respectively employing a bench scale facility. Effects of steam injection were also investigated at the temperature of 600℃. The time change of the pyrolysis gas composition was measured. It was found that the High Heating Value (HHV) of pyrolysis gas increases with increasing the pyrolysis temperature, and the peak valueappears at the early stage of the pyrolysis. It was also demonstrated that steam can significantly facilitate cracking of high molecular compounds and decompose char into H_2,CO and CO_2,especially in the case of wood chips, where about twice gas yields was successfully obtained by steam injection.
