Thermal Power Plant, Working of Thermal Power
In thermal power plant the coal is first grind into powder which burns faster and produces more heat. After grinding hot air is passed through it to remove moisture from it. The pulverized coal is transfer to The coal-pulverizer is an important unit, which pre-processes coal-fuel fed to the boiler in coal-based thermal power plants. It is extremely important to comprehend the operational behavior of the coal pulverizer unit for good performance of the boiler and overall coal power-plant.
