| 中文摘要 | in this study, we analyzed the operational characteristics of a 1.2-mw rice husk gasification and power generation plant located in changxing, zhejiang province, china. the influences of gasification temperature, equivalence ratio (er), feeding rate and rice husk water content on the gasification characteristics in a fluidized bed gasifier were investigated. the axial temperature profile in the dense phase of the gasifier showed that inadequate fluidization occurred inside the bed, and that the temperature was closely related to changes in er and feeding rate. the bed temperature increased linearly with increasing er when the feeding rate was kept constant, while a higher feeding rate corresponded to a lower bed temperature at fixed er. the gas heating value decreased with increasing temperature, while the feeding rate had little effect. when the gasification temperature was 700-800c, the gas heating value ranged from 5450-6400kj/nm3. the water content of the rice husk had an obvious influence on the operation of the gasifier: increases in water content up to 15% resulted in increasing er and gas yield, while water contents above 15% caused aberrant temperature fluctuations. the problems in this plant are discussed in the light of operational experience of mw-scale biomass gasification and power generation plants. |
