Abstract
The effect of halogen species on CO oxidation in circulating fluidised bed combustion has been studied with combustion experiments with iodine addition. As iodine concentration increased to 0.4%, CO concentration in the flue gas increased by two orders of magnitude. The markedly increased CO concentration is attributed to increased recombination of hydroxyl radicals, the principal oxidant of CO under combustion conditions, catalysed by iodine. An equation based on the branching-chain theory is developed to describe the kinetics of CO oxidation and the effect of iodine. The same equation is also able to describe the effects of chlorine and bromine species on CO concentration in combustion of coal, and the effect of HCl on CO concentration in combustion of pyridine. Based on these results it appears possible to give a generalised description of CO oxidation and the inhibition effect of various halogen species using a single equation.

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
