摘要

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

远大于炭化炉熔盐加热层的对流传热系数h

；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。

Abstract

Using molten salt as a heat medium to form a high-temperature molten salt heat exchange system

a set of molten salt heat storage and carbonization device was designed. The structure and rated working conditions of the molten salt-carbonization furnace were designed

and the Nu empirical formula was applied to calculate the composite surface heat transfer coefficient of the molten salt-cylinder wall

and the relevant small-scale carbonization tests were carried out. The results showed that the convective heat transfer coefficient hti of the molten salt in the pipeline was much greater than the convective heat transfer coefficient ho1 of the molten salt heating layer of the carbonization furnace. The theoretical thermal efficiency and the measured thermal efficiency of the biomass carbonization device increased with the carbonization temperature. With the increase in carbonization temperature

decrease in material handling capacity

and extension of carbonization time

the calorific value of the products increased

but the solid energy yield decreased. Compared with rice husks

the organic components of pine wood shavings were more likely to escape into tar and even the vapor phase during the carbonization process. The designed experimental device can realize the carbonization of biomass under the condition of storing molten salt as a heat medium

which achieves the purpose of energy saving and carbon dioxide emission reduction.
