石煤沸腾自热钠化焙烧是从含钒石煤中提取 V_2O_5的一种较为先进的工艺路线,石煤既是燃料又是原料,得到了综合利用。中间试验已基本获得成功。本文介绍了“石煤和石煤渣提取五氧化二钒中间试验(浙江诸暨粉状行煤沸腾焙烧工艺)”热工试验部分的研究结果。着重阐明了煤沸腾自热钠化焙烧的热工过程和其优惠焙烧条件、热量的合理利用和受热面的使用寿命等有关问题。
Boiling coal self-heating roasting sodium roasting is extracted from vanadium-containing coal V_2O_5 a more advanced technology route, both coal as fuel and raw materials, was comprehensive utilization. Intermediate tests have been basically successful. This paper presents the results of the thermal testing of the “Intermediate Test of Extraction of Vanadium Pentoxide from Stone Coal and Stone Cinder (Zhejiang Zhuji Powdered Coal Boiling and Roasting Process)”. Emphatically expounded the thermal process of coal boiling self-heating sodium calcination and its preferential baking conditions, the rational use of heat and the service life of the heating surface and other related issues.
