【摘要】 根据生物质颗粒内部燃烧过程和生物质粉自然向下阴燃过程的共性,采用阴燃实验的方法研究了生物质内部燃烧特性。考查了物料种类、含水率、孔隙尺寸对生物质内部燃烧温度,燃烧中干燥前沿、炭氧化前沿的移动速度,裂纹、气体成分等的影响。实验结果为生物质燃烧和阴燃过程模拟以及深入理论分析提供了依据。更多还原

【Abstract】 Combustion characteristic inside biomass has been investigated via smoldering experiments according to the similarities between combustion inside biomass particle and natural downward smoldering of biomass powder.The effects of fuel type,moisture content and pore size on temperature inside fuel bed,propagation velocity of drying and char oxidation fronts,cracks and gas products were examined.The results can be used in modeling validation of biomass combustion and smoldering.更多还原
