Realtime coal classification in thermal power plants

Realtime coal classification in thermal power plants

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.

How a Coal Plant Works

How a Coal Plant Works. Coalfired plants produce electricity by burning coal in a boiler to produce steam. The steam produced, under tremendous pressure, flows into a turbine, which spins a generator to create electricity. The steam is then cooled, condensed back into water and returned to the boiler to start the process over. Here's a real ...
