Ques 123. Which of the following is/are characteristic/characteristics of Indian coal? 1. High ash content 2. Low sulphur content 3. Low ash fusion temperature Select the correct answer using the codes given below A. 1and 2 only B. 2 only C. 1 and 3 only D. 1, 2 and3 the
Ans, A EXPLANATION 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. DIndian coal's sulphur content is low, about o.5 per cent Indian coal has high ash fusion temperature of about 1,500; reason for its non suitability in entrained gasifiers (which are used in other countries)
Ques 124. Which of the following is/ are the reasorn (s) behind Gujarat being leading producer of Salt in India? 1. Long length of coastline 2. Long Duration of hot and dry conditions 3.
