糖厂锅炉的分析模型研究

Study on Exergy Analysis Model of Boiler in Cane Sugar Mills

甘蔗制糖业是广西支柱产业,并且是高能耗行业。以某日榨7 000吨的甘蔗糖厂为例,对其锅炉建立分析模型并进行了能量分析,结果效率比热效率低一半左右。分析模型揭示了糖厂锅炉的能耗来源,为糖厂锅炉的节能降耗优化改造提供了理论支持。

Cane sugar manufacturing industry was a main industry in Guangxi, and was a highly energy-consuming trade. Taking a sugar mill of daily output of 7 000 t and making an exergy analysis of its boiler, the results showed that the exergy efficiency was lower about a half than that of the thermal efficiency. The exergy analysis model showed the origin of the energy loss, and could provide theoretical support for energy saving and optimal modification of the boiler in cane sugar mills.
