Q: Which of the following is/are the characteristic/characteristics of Indian coal?
- High ash content
- Low sulphur content
- Low ash fusion temperature
Select the correct answer using the codes given below:
a) 1 and 2 only
b) 2 only
c) 1 and 3 only
d) 1, 2 and 3
Correct Answer: Option (a)
- The most significant characteristic of Indian coal is its high ash content, which varies from 35 to 45 per cent, compared with that of coal in other parts of the world, which is around 15 per cent.
- Besides high ash content, another reason for entrained gasifiers (that operate at higher temperatures than fluidised bed gasifiers), commonly used in IGCC plants abroad, being not suitable for Indian coal is its high ash fusion temperature of about 1,500. However, Indian coal’s sulphur content is low, about 0.5 per cent.
- Hence, option (a) is correct.
