熔盐炉及熔盐加热系统

在氧化铝生产过程中,由于我国一水硬铝石型铝土矿存在高铝、高硅、可磨性差和难溶出的特点,管道化溶出方式逐渐成为一种发展趋势,而熔盐炉是管道化溶出系统中最关键的加热设备。结合某氧化铝厂管道化溶出系统熔盐炉及熔盐加热系统,介绍了熔盐的组成及特性,熔盐炉的类型与结构,熔盐加热系统的运行和特点。

Summarizing on Molten Salt Oven and Molten Salt Heating System

Because the diasporite mineral in China has characteristics of high aluminum, high silicon, hard grinded and hard digested,tube digestion has become a developing direction in the alumina production processing,and molten salt oven is the most important heating equipment of the tube digestion system. Based on the molten salt oven and the molten salt heating system of the tube digestion in an alumina plant, the composition and property of molten salt, the type and structure of molten salt oven, and the operation and feature of molten salt heating system are introduced.
