1) Practicability of an automatic system for pyrolytic gasification of rice husks, composed of gas generation and its control, gas cleaning, and temporary gas reserve, and the possibility of utili­zation of the husk-gas were distinctly recognized.
　2) The husk-gas has strong odor. It was gener­ated at the rate of 1 m³ per 1 kg of rice husks. It's composition was CO 20%, H₂ 10%, CH₄ 2%, C₂H₄, C₂H₆, etc. 5%, O₂ 3%, CO₂ 10% and N₂ 50%. Excess air ratio=0.95, and net calorie=1,000 kcal/m³.
　3) Repeated practical operation tests conducted with a pilot plant of the automatic pyrolytic gasification system for rice husks demonstrated that this new system is highly practicable.
