Indian Coal Characteristics
Indian coal is known for its specific characteristics that distinguish it from coals found in other parts of the world. The following are the key characteristics of Indian coal:
1. High Ash Content:
Indian coal is known to have a high ash content. Ash is the inorganic residue that remains after coal combustion. It contains various minerals and impurities such as silica, alumina, iron, and calcium. The high ash content in Indian coal can affect its combustion efficiency and increase the amount of waste generated during combustion.
2. Low Sulphur Content:
One of the positive characteristics of Indian coal is its low sulphur content. Sulphur is a harmful element that contributes to air pollution and acid rain when coal is burned. Indian coal typically contains lower levels of sulphur compared to coals found in other countries. This low sulphur content makes Indian coal environmentally friendly and suitable for power generation and industrial applications.
3. Low Ash Fusion Temperature:
Indian coal is also known to have a low ash fusion temperature. The ash fusion temperature refers to the temperature at which ash particles in coal melt and form clinkers or slag. A low ash fusion temperature can cause operational issues in boilers and furnaces as the melting ash can stick to the heating surfaces and hinder heat transfer. Indian coal's low ash fusion temperature can pose challenges in efficient combustion and maintenance of equipment.
Therefore, the correct answer is option 'A' (1 and 2 only), as Indian coal is characterized by high ash content and low sulphur content. While Indian coal does have a low ash fusion temperature, it is not mentioned in the given options.
