Summary

Batch and cullet heat exchange with the flue gas permits recycling of otherwise inaccessible flue gas enthalpy. Various designs for batch preheating will be described and compared. The merits of a packed bed direct exchange preheater are noted. Heat transfer calculations reveal that significant energy saving; can be realized even on efficient regenerative furnaces. The savings depend either on the temperature of the flue gas exiting the regenerator or on batch and cullet sticking behavior. Experimental results on sticking will be presented. Capture of SO2 and perhaps NOx by the batch depends on a number of factors, e.g., batch temperature and batch particle size. Experiments simulating the effect of some of these factors on SO2 removal will be presented.
