内热式盐浴炉启动方法很多,虽各有特点,但也各有不足,如启动时间长(3～5h),热效率低,能量浪费大,有的还需增加辅助设备或部件,操作复杂,安全性差等。由于启动不便,盐炉不工作时,往往要通电保温而消耗大量电能。现行盐炉启动方法所引起问题的原因虽然是多方面的,我们认为有两条是比较重要的。(1)本来是内热式的盐浴炉,但在启动过程中,却把盐浴变成了被加热物质,必须另加发热体。(2)启动过程中大都是以传导方式加热使盐熔化,加热速度慢,热效率低,热损失大。
There are many ways to start the thermal salt bath furnace, though each has their own characteristics, but they also have their own drawbacks. For example, the starting time is long (3-5h), the thermal efficiency is low, the energy is wasted, and some additional auxiliary equipment or components are needed. Poor security and so on. Due to inconvenient to start, salt stove does not work, often have to electricity and heat and consume a lot of power. Although the causes of the problems caused by the current salt furnace start-up method are manifold, we think two of them are more important. (1) Originally an internal heat type salt bath furnace, but in the start-up process, but the salt bath into the heated material, you must add another heating body. (2) Most of the start-up process is heated by conduction to melt the salt, slow heating, low thermal efficiency and large heat loss.
