上吸式秸秆气化炉中当量比对气化特性的影响
Effect of Equivalence Ratio on Gasification Characteristics in a Straw Updraft Gasifier
摘要
Abstract
China produces abundant biomass waste during agriculture process, and biomass gasification technology is a clean and high efficient way to use biomass energy. Using a self-developed updraft gasifier as carrier, the effect of equivalence ratio Φ on gasification characteristics was studied through experimental methods in an updraft gasifier. The results obtained show that the optimal value of Φ is between 0.25 and 0.3 under the experimental condition, the mean temperature in gasification reaction zone can reach 950℃, heating value of 5.98MJ/m3, gasification intensity of 137.7kg/(m2·h), gas production rate of 1.68m3/kg, carbon conversion rate of 86.4%, and 73.3% for the overall gasification efficiency. The tar content in gas increase slowly with increasing equivalence ratio when Φ is below 0.3, but the tar content increase rapidly when Φ is above 0.3.关键词
