Sludge Mass Reduction: Primary Compositional Factors That Influence Melt Rate for Future Sludge Batch Projections

Melt Rate Furnace Testing for Sludge Batch 5 Frit Optimization

“…Recent testing 5 to evaluate the effect of aluminum dissolution on melt rate also show a similar relationship between boron and alkali ratios.…”

“…A maximum B 2 O 3 level before melt rate drops off is indicated, but may be confounded by the changing total alkali content. Separate MRF testing for the aluminum dissolution process indicated a critical B 2 O 3 +Na 2 O content which if exceeded, melt rate was reduced 5 . Table 12 shows both the frit compositions and their respective melt rates.…”
