Abstract

To improve the safety and stability of MPS medium speed coal mill operation

from the perspective of mass and energy balance

based on the principles of system dynamics and by taking the casual loop diagrams and the stock flow diagrams as the carrier

MPS medium speed coal mill system model was established according to its working principle.Moreover

by taking the MPS190 medium speed coal mill as the research object

the simulation experiment of the model was carried out in the system dynamics software Vensim PLE to simulate the step increase of coal quantity and that of inlet air temperature.The comparison between the simulation results and differential equation model simulation results shows that

the established model can accurately reflect the characteristics of MPS medium speed coal mill

the system dynamics is simple and easy to understand

which can conduct efficient modeling and research for MPS medium speed coal mills in power plants.
