Since some of the projects are exothermal reaction and some are endothermal, a total of 200,000 tons of standard coal can be saved through internal heat conversion. |
One may see from the Figure that in the process of heating exothermal phase transformations occur in the foils. |
The process took advantage of the exothermal effect of reactions. |
This fine dust will react again with oxygen in an exothermal reaction. |
