| Abstract: | Based on the principle of biomass gasification, the method, updraft gasification in fixed beds, is adopted to study the process of biomass gasification. After setting up a small-scale test gasifier and analyzing sampled gases, the heat value of gasified gas is available. Tested data method is used to calculate gasification criterions, and at the same time, the effects of temperature of gasifier, characteristics of raw materials, thickness of fuel on the biomass gasification are discussed. A mathematical model is established to simulate the process of gasification and study the chemical reaction in the gasification furnace. Ingredients and heat value of simulated gases are compared with corresponding tested data. The feasibility of updraft gasification in fixed beds is verified. |
