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 importan.
Oct 26, 2017· A mathematical model was established which describes the co-combustion of pulverized coal (PC) and polyethylene particles (PEP) in this study. The model was designed to be incorporated into an overall model simulating PC and PEP process. The combustion model of PC and PEP takes into account the principal physical and chemical phenomena occurring during the pyrolysis and .
The presence of combustible materials in the pulverizer is usually the largest contributor to pulverizer fires. In most cases, pulverizer fires begin in the under bowl area of the pulverizer that is a very hot environment with an abundance of air. Accumulations of debris or coal anywhere in the pulverizer will increase the chance of a mill fire.
