2. The hot air is used for transportation of the recirculating coal within the mill and also for transporting the coal from the pulverizer to the furnace. As the coal is continuously reduced in size, the smaller/lighter particles are swept from the bowl by the hot air. Hot air (and cool tempering air) is provided by the primary air fans.

Indian coal contains sulphur in the range of 0.2–0.7 per cent by weight. With this sulphur content, it is estimated that coal-based power plants in India emit SO 2 in the range of 800–1,600 mg/Nm3.6 SO 2 emission can be controlled at three stages: I. Pre-combustion: Sulphur content in the coal can be reduced through coal washing; II.
