摘要(Abstract)：

以熔盐充当热媒形成高温熔盐换热系统，设计了一套熔盐储热炭化装置。对熔盐-炭化炉进行结构和额定工况设计，将Nu经验公式应用于熔盐-筒壁的复合表面传热系数的计算，并开展相关小试炭化实验。结果发现：管道内熔盐的对流传热系数h_(ti)远大于炭化炉熔盐加热层的对流传热系数h_(o1)；炭化炉理论热效率和实测热效率均随炭化温度的提升而升高；随炭化温度升高、物料处理量减少以及炭化时间延长，产物热值升高，固体能量产率降低；相较于稻壳，松木刨花在炭化过程中有机物组分更易逃逸至焦油乃至气相中。所设计的实验装置实现了以储热熔盐充当热媒条件下的生物质炭化，可达到节能并减少二氧化碳排放的目的。
