All air and material goes to a form of intermediate storage like a bag filter, and from the bag filter it mechanically or pneumatically goes to a silo, where it will be fed to the burners. He said that in recent cases like the September 29 boiler explosion in India, a direct coalfired system was likely being used to generate power for the plant.

Abstract. Continuous variations in coal quality have a strong influence on operation of thermal power plants. However, in absence of realtime measurements of quality, the operators remain partially blind to the actual coal being consumed, leading to suboptimal operation. A twostage solution is proposed for realtime soft sensing of coal type.
