Based on electromagnetic induction heating technology, a fluidized bed gasification reactor based on induction heating was manufactured. It could provide heat for the biomass gasification process from the inside, and control the gasification reaction temperature accurately. Taking rice husk as raw materials of biomass, steam and air gasification as gas agent, biomass gasification for hydrogen production experiment was carried out. The effects of reactor temperature, steam to biomass ratio (S/B), and equivalence ratio (ER) on gas composition and hydrogen yield were investigated. According to the experimental results, it was found that when the reactor temperature was 800℃, the hydrogen content increased with the increase of S/B or the decrease of ER, hydrogen yield reached its maximum at the S/B of 1.5 or at the ER of 0.22. The highest hydrogen content (35.47%) and the highest hydrogen yield (78.22g/kg), was achieved simultaneously at a reactor temperature of 950℃, ER of 0.22, and S/B of 1.5.
