Numerical Study of Solid Biomass Fuel in a Gasifier System

Abstract:

In this study, the gasification processes of different Taiwan’s agriculture wastes were studied by using software of Fire Dynamics Simulator (FDS), which developed by American National Institute of Standards and Technology (NIST), to build a model of downdraft fixed bed gasifier. Details of the operation condition for the Taiwan’s agriculture waste biomass fuel in the gasifier were obtained. They include traction fan speed, leakage air, internal temperature, moisture, and cold gas efficiency. The simulated results are found in small type fixed bed biomass gasifier under traction fan initial speed is 0.2m/s, the leakage air in the gasification area is less than 10% of the amount of wind quantity by traction fan and moisture content of solid biomass is limited at 10% ~ 20%(vol.) that temperature in gasification zone with steady supply fuel gas condition is near 850~900°C.
