Coal utilities are currently the major source of electricity in India. Share of coal fired power is usually in the range of 60%65% (Ministry of Power 2020; Department of Industry 2020).Though the share of solar and wind power has increased over the last two decades, coal would continue to dominate the electricity sector in India in next few decades.

Coal was the thirdlargest energy source for electricity generation in 2022—about 18%. Nearly all coalfired power plants use steam turbines. A few coalfired power plants convert coal to a gas for use in a gas turbine to generate electricity. Petroleum was the source of less than 1% of electricity generation in 2022.

Volatile matter (VM) is the percentage loss in mass, adjusted for moisture, when coal is heated out of contact with air under standard conditions. In this test, 1 g of sample is placed into a lidded crucible (to prevent ingress of air), which is placed in a furnace at 900 °C for 7 min or 950 °C if using the ASTM method. Moisture in the analysis sample is determined concurrently.

Process. Direct reduction processes can be divided roughly into two categories: gasbased, and coalbased. In both cases, the objective of the process is to remove the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc.), in order to convert the ore to metallic iron, without melting it (below 1,200 °C (2,190 °F)).
