Abstract

fetched live from OpenAlex

Two mill trials were conducted in a recovery boiler at a kraft mill in Sweden using a force measurement probe to examine the performance of a sootblower under different blowing conditions. The results show that at a given distance, the force produced by the sootblower jet increases almost linearly with an increase in lance pressure. At a given lance pressure, the jet force decreases rapidly as the distance increases, retaining less than 10% of its original strength at a distance beyond 1 m from the nozzle. The results also suggest that flue gas temperatures in the vicinity of the sootblower have an insignificant effect on sootblower performance, and that the sootblowing jet force exerted on a tube target can fluctuate widely, particularly at a close distance. Force fluctuations are caused mainly by the vibration of the target as it is struck by the jet. The change in jet strength is caused by platen swinging and the tremor of the system that holds the target.

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.
