Propagation of Smouldering in Wood Dust Deposits Ignited by Embedded Hot Bodies
Bibliographic record
Abstract
ABSTRACT Combustible dust poses a hazard to industry in two ways, i.e., reactive as a cloud or reactive as a pile. This paper deals with the smouldering behaviour of wood dust deposits initiated by hot bodies. Effects of embedded depth and airflow condition are investigated. Two sizes of wood dust are selected as test samples, namely wood powder and wood chip. The results indicate that under the same hot bodies embedded depth, wood chip combustion propagates faster than wood powder in general due to its unique flocculent structure. Due to the increased insulation effect of the wood dust layer, the temperature at the same measuring point is higher than that of the wood chip layer. In addition, under airflow conditions, the smouldering propagation of wood deposits is significantly higher than that without airflow (2.42 and 4.34 m/s) for both wood powder and wood chip samples. However, the deposited wood powder has a lower minimum ignition temperature than wood chip. Accumulated wood dust in considered to have a greater fire risk in powder form.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
