Investigation and Optimization of the Technological and Functional Performance of the Ventilation Mill in the Thermal Power Plant Kostolac B

The research as part of this project includes optimization of work activities of the ventilation mill to increase overall energy efficiency of the thermal power plant Kostolac B. The working life of mill components exposed to intensive abrasive wear and tear shall be monitored and assessed, with a focus on parts whose revitalization by projection welding is included in project TR19205. This project shall include revitalization and/or substitution of suction and lined panels in parts of the mill for which the results of previous research have pointed to critical points exposed to intensive abrasive wear and tear. The primary goal of this research is to accept the implementation of new materials and processes of revitalizing the working parts of the ventilation mills. Also, there shall be a numerical simulation of the multiphase airflow in the ventilation mill-canal system of the aeromixture of the discrete phase Lagrange model. Numerical simulation shall be performed for different geometries of blinds and a centrifugal separator, different granulations of coal dust and mineral matter, aimed at the most cost-effective manner of determining the technical and technological parameters for optimizing the air flow. A part of the numerical simulations shall include the process of heat distribution and exchange between the ventilation mill and the environment.
