Abstract

fetched live from OpenAlex

The emission characteristic of oxidized and elemental mercury from fly ashes collected from Guangzhou Pearl River Power Plant(1#)and the First(2#)Second(3#)Electric Fields of Guangzhou Petrochemical Plant was investigated during thermal treatment using Ontario Hydro Methods(OHM). Under different calcination temperature(200 ℃,400 ℃,600 ℃,800 ℃ and 1000 ℃),and different calcination time(30 min,60 min,90 min and 160 min),the emission amount of oxidized and elemental mercury from the fly ashes was determined subsequently. Results showed that the emission amount ranged from 1.955 ng to 669.87 ng for oxidized mercury and from 14.53 ng to 3501.15 ng for elemental mercury per gram fly ash during thermal treatment. When the fly ash was calcined up to 60 min,all the mercury existing in both forms was mostly emitted. The emission reached to the maximum at calcination temperature of 600 ℃(except for 3#)for oxidized mercury,and at 400 ℃ for elemental mercury. The emission amount of mercury was proportional to the unburned carbon content in fly ashes.

Full frame distilled prediction

Teacher imitation

Not 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.
