| Abstract |
| Hatch and cullet heat exchange with the flue gas permits
recycling of otherwise inaccessible flue gas enthalpy. Various
designs for hatch preheating are described and compared. The
merits of a packed bed direct exchange preheater are noted.
Heat transfer calculations reveal that significant ene1ˇgy
savings can be realized even on efficient regenerative furnaces.
The savings depend either on the temperature of the flue gas
exiting the regenerator or on hatch and cullet sticking behaviour.
Experimental results on sticking will be presented.
Capture of S02 and perhaps NOx by the batch depends on a
number of factors, e.g. batch temperature and batch partkle
size. Experiments simulating the effect of some of these factors
on so2 removal will be presented. |
