💡 Analysis & Explanation
Origin of Material
Furnace oil, also known as fuel oil, is a dark, viscous residual product obtained during the fractional distillation of crude oil in petroleum refineries. Thus, statement 1 is true.
Industrial Application
Because it is relatively cheap, many heavy industries and manufacturing plants utilize furnace oil in boilers, furnaces, and large generators to produce steam or thermal power. Therefore, statement 2 is correct.
Environmental Impact
As a heavy residual fuel, furnace oil typically contains a high concentration of sulphur. Burning it results in significant emissions of sulphur oxides (SOx) into the atmosphere, which is a major environmental concern. Hence, statement 3 is correct.
Conclusion
All three statements accurately describe the nature, use, and impact of furnace oil.
