ABSTRACT:
A method and system for determining the behavior of a regenerator in a glass furnace performs a heat transfer analysis on each differential portion of the regenerator. The method and system determines a temperature profile within the regenerator for each differential space along the regenerator and for each period of time. Based on this finite difference analysis, the amount of heat transfer from the regenerator to primary air and the amount of heat transfer from the flue gas to the regenerator is determined. The method is an iterative method with the results from each pass being compared to the results from the previous pass to determine the quantity which had the largest difference. When the largest difference between successive passes is less than a certain tolerance, the method is considered to have converged. Because the iterative method may be time consuming, a simplified method of analyzing a regenerator derives a relationship between an air side regenerator outlet temperature and an air flow rate, and a relationship between the air side regenerator outlet temperature and a temperature at the flue gas exit of the melter. Based on values of the air flow rate and the temperature at the exit of the melter, the air side regenerator outlet temperature is determined followed by the amount of heat transfer through the regenerator. The results of the simplified regenerator model are input to a full regenerator model and enable the full regenerator model to converge more quickly, thereby reducing the amount of processing time.
