Industrial Coal Pulverizer Model Simulation and Parametric

2018-1-1  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

Numerical simulation of particle breakage in dry impact

2013-10-1  A novel method to simultaneously simulate particle motion and its breakage in a dry impact pulverizer was developed. The motion of particles in the pulverizer was calculated using a discrete phase model (DPM)‐computational fluid dynamics (CFD) coupling model. When the particle impacts against a vessel wall, impact stress acting on the particle is calculated from Hertz's theory as a function
