一、自制硝盐炉改造硝盐炉加热均系采用外热式电阻加热,它的改造如图1、图2。图1称其为全封闭式,图2为半封闭式。前者优点是升温快、节电效果显著;后者只是电阻丝搁砖未用陶瓷纤维毡封闭,优点是节省材料、改装方便。缺点是节电效果不如全封闭式显著。表1为改造前后性能比较。

First, the transformation of homemade salt spray salt furnace nitrate salt furnace are heated by external thermal resistance, its transformation shown in Figure 1, Figure 2. Figure 1 called the fully enclosed, Figure 2 is semi-enclosed. The former advantage is rapid heating, energy-saving effect is remarkable; the latter is only resistance wire laying brick not closed with ceramic fiber felt, the advantage of saving material, easy modification. The disadvantage is that the power saving effect is not as obvious as a fully enclosed. Table 1 before and after the transformation performance comparison.
