摘要 Based on the analysis of heat transfer mechanics,physical and chemical change of pellet drying and preheating process in grate,the mathematical model is established and solved by three-diagonal matrix algorithm. With Visual Basic 6.0 a simulation software is developed.The model is verified by measurements at a domestic pellet plant,and the temperature distribution of pellet bed is gained.Meanwhile,the influence of different operation parameters on the pellet thermal process is studied.The results can be taken as a basis of practical production control and the grate optimizing design.
