> The Kansai Corporation rice husk gasifier is interesting. They feed 150 kg/hr husk at 2000 kcal/kg and get 50 kg/hr char. It is a stirred bed gasifier. Husks gasifying in the bed at about 600C. Air is added above the bed to burn the gases. Stack gas is 15% O2 so they use lots of excess air. About 30% of the heat input is recovered as hot water which is used in the bio oil process and in winter for heating.
