| Abstract: | Theoretical analysis is done based on the heat transfer mechanism of rotary air preheater,and mathematical model is established correspondingly.Based on the definition of dimensionless temperature,dimensionless time and dimensionless length,matrix theory is adopted to set up mathematical model in order to analyze the curves of air,gas and metal temperature.The temperature distribution of heat-storage boards is calculated,and the result indicates that the calculation can precisely reflect the lowest wall tem... |
