Rice husk is one of the attractive renewable energy sources in Asia. Several studies have reported that rice husk biochar produced by some energy conversion systems is dangerous to human because it contains crystalline silica. The purpose of this study is to develop an effective gasification technology which can prevent crystallization of silica. Rice husk is converted to producer gas at about 1000 degree C in new type of gasifier for tar cracking. This gas is clean and stable enough to produce 15kWe electric power by gas engine CHP. Biochar from this gasifier is analyzed using XRD and the peak of Cristobalite is not detected. These results indicate that new type of gasifier can satisfy both power supply and prevention of silica crystallization by using rice husk.
