Modeling of Rice Husks Gasification in a Fluidized Bed Reactor

Aug 15, 2004 · Experiments on a cold model show that rice husk is difficult to be fluidized, and adding silicon sand and coal improves the fluidization condition. Effects of sand diameter, gas velocity and mass fraction on rice husk mixing were tested. The rice husk can mix well with 0.3–0.8 mm sand at gas velocity 0.8–2 m/s.
