As biomass utilization has the problems of collection and transportation, a small-scale dispersed power source should be required. On a small scale, biomass gasification is one of the most efficient energy conversion technologies. However, almost gasification system has not been put to practical use. Some of the causes are the technical problems of highly tar-contaminated gas and exact requirements for fuel quality. Yanmar has developed not only dual fuel engine CHP, but also gasification system. Originally designed open top downdraft gasifier can achieve uniform temperature and produce low tar gas without ash melting. This gasifier has a potential to use a wide variety of biomass. This report reviews the recent development and future prospects on fixed bed downdraft gasifier and dual fuel engine.
