Characteristics of Indian Coal

Indian coal is characterized by high ash content (typically 20-45%), which is one of its distinguishing features. It also contains low sulphur content compared to coals from other regions, making it relatively environment-friendly in terms of sulphur emissions. However, Indian coal typically has a high ash fusion temperature rather than low, as it contains refractory minerals. Statement 3 is incorrect because Indian coal generally exhibits high ash fusion temperature. Therefore, statements 1 and 2 are correct. > KEY POINT: Indian coal = High ash + Low sulphur + High ash fusion temperature. Answer: (a).
