Abstract
Systematic combustion experiments of mixed fuels with different ratios of petroleum coke over coal are conducted on a 0.5MW_t pilot-scale CFB facility. The effects of various parameters, in terms of the ratio of petroleum coke over coal, the excess air coefficient, the bed temperature, the primary air fraction, the Ca/S ratio on the N_2O emission in the flue gas are revealed in this paper. It indicates from the experiments that with increasing in the ratio of petroleum coke over coal, N_2O emission concentration rises. For puree petroleum coke as fuel, N_2O emission concentration is the lowest than other mixed fuels. It is shown from experimental results that for all fuel mixtures with the primary air fraction, the excess air coefficient and the Ca/S ratio increasing, N_2O concentration rises. When the bed temperature increases, the N_2O concentration drops.

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
