摘要/Abstract

摘要： 通过实验的方法对生物质气化过程中床层压降的影响进行研究,以空气为气化剂进行了生物质气化特性试验,考察了气化参数对生物质产气质量的影响。分析了压力、温度、热值三者间的内在联系。研究结果表明:在实验工况下,最佳压降范围为1.6～2.9 kPa,此时炉内氧化层温度达到1 000～1 300 ℃,燃气热值为4 900～5 700kJ/m³,焦油质量分数随温度升高而降低,在炉内压降超过2.9 kPa时氧化层温度降低,因此,在最佳压降范围内,压降提高有利于燃气质量的改善,该结论可以对气化炉床层反应动力学研究提供参考。

Abstract: The influence of bed pressure was investigate by the method of experiment. Air was used as gasifying agent during the biomass gasification experiment. Analysised the inner relationship of pressure, temperature and calorific value. The study results showed that optimum pressure range was 1.6-2.9 kPa in the experimental condition. In this pressure environment, the temperature of oxide layer reached 1 000-1 300 ℃, calorific value reached 4 900-5 700 kJ/m³, tar content decreased with the increasing temperature. However the oxide layer temperature decreased when pressure drop exceed 2.9 kPa, therefore, the influence of pressure on gas quality appeared fluctuating trend, research results could provide a reference for the study on kinetics of reaction of biomass gasification.

Key words: active-air gasification, pressure drop, production gas, kinetics of reaction, calorific value
