Abstract
Agglomeration due to the sulfation process itself occurs in CFBC boilers firing high-sulfur fuels such as petroleum coke. This study examines the effect of CaSO 4, the effect of limestone reactivity, and the potential effect of reactivation on strength development in such deposits. A very unreactive crystalline limestone showed a lower sulfation level over longer times (days to weeks), but the extent of sulfation did not correlate to strength development. This work also shows that CaSO 4 by itself cannot produce significant strength development in the ash samples. Finally, reactivation by hydration did not contribute to strength development under the conditions of this study.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
