生物质压缩成型机理研究进展

Progress in research of biomass molding mechanism

生物质成型燃料以其能量密度和质量密度较大、颗粒均匀、含水率稳定等特点,在城镇和农村家庭炊事、取暖、工业锅炉或窑炉的燃料替代等方面得到了广泛的应用。文章主要介绍了生物质成型过程中原料预处理、成型参数、成型模型、原料成分、粒子结合方式等方面的研究进展。针对几个方面的研究现状,提出从木质素热转变特性的角度揭示成型机理、混配原料粒子间结合方式的研究等应为成型机理研究的主要方向。

Due to the features of relatively high energy density, uniform size and stable moisture content, biomass molding fuel has been widely used as fuel for household cooking, space heating,industrial boiler and kilns. This review summarizes the studies on biomass molding together with the analysis of influence factors, such as feedstock pretreatment, molding parameters, molding models, feedstock composition and particle combination. Study of thermal transformation of lignin and particle combination during mixed feedstock molding are important research directions.
