Abstract
Fluidized bed annealing furnaces used for annealing low- and medium-carbon wire products have been used for a number of decades as an environmentally friendly alternative to more traditional heat treating systems based on molten lead. Recent investigations into heat transfer rates to wires immersed in a fluidized bed have shown that the heat transfer rate is relatively constant over a wide range of fluidizing rates, contrary to earlier thinking. As a result, it is possible to modulate air/gas flow rates in these systems without affecting product quality due to variable heat transfer rates. Typically, systems have operated at constant fluidizing air flow rates with either on/off gas control, or modulating gas only, resulting in high effective excess air operation and resulting low thermal efficiency. This work investigates the result of operating a fluidized bed with modulating air/fuel flow rates at fixed air/fuel ratios, resulting in improved thermal efficiency. Results indicate that significant fuel savings can be achieved, particularly at lower load levels.

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
