Abstract

The coupling between the pulverized coal combustion and raw meal decomposition in precalciner of the cement plant with capacity of 5000t/d was investigated by Fluent software. The standard k- model was proposed to simulate the three-dimension turbulence flow. The multiphase was calculated coupling process. The non-premixed combustion model was applied to the chemical reaction. The energy generated by chemical reaction was expressed the PI radiation model. The particle stochastic trajectory model was abided by track particles movement. The simulate results show the field of temperature and CO2 concentration with three decomposition ratio 85%, 88% and 92%. This provides the thermal data for the producers and managers in the cement plant.
