A BIOMASS PYROLYSIS GASIFIER APPLICABLE TO RURAL CHINA

A pyrolsis gasifier was developed to make use of indigenous biomass to help solve the problem of rural energy shortage particularly in engine fuel shortage and to reduce pollution. First, (low diagram of pyrolysis gasification system was designed and the sketch of gasifier was drawn. Second, the gasifier thus drawn was made. It was successfully operated with corncob feeding. Its performance parameters were measured in an experimental scheme designed according to an orthogonal test table. A variance analysis was taken of the results were taken to sort out the best experimental condition. A run on such conditions gave a heating value of the gas as high as 12.4MJ/nm³ and without tar, a conversion rate about 60.2%, and a total energy efficiency about 59.3%. Regressive analysis of the data that shows the flow rate of the gas is an exponential function of time. Finally, explanations to the analysis results of the data and what problems of the gasiSSfier to be tackled were given.
