Features of Indian Coal
●  High Ash Content: Indian coal contains a lot of ash (non-combustible material), which reduces its efficiency and requires proper disposal. Hence, Statement 1 is not correct.

● Low Calorific Value: It generates less heat per unit compared to higher-quality coals like Australian or Indonesian coal. Thus, Statement 2 is correct.

● Low Sulphur & Phosphorus: This is an advantage because low sulphur means less air pollution (SO2 emissions), and low phosphorus is beneficial for industries like steel manufacturing. Thus, Statement 3 is correct.

● High Ash Fusion Temperature: The ash in Indian coal does not melt easily, which helps in certain industrial processes but can also create operational challenges in boilers. Thus, Statement 4 is not correct.
