Industrial Coal Pulverizer Model Simulation and Parametric

Jan 01, 2018 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. This paper describes the first principle based energy and mass
