Abstract
Three different lithotypes of Longyan (LY) anthracite with different particle size were separated by means of flotation technique. Experiments of the particle fragmentation during pyrolysis and combustion were conducted in a TGA system and a pilot scale fluidized bed furnace, respectively. It is shown that for clarain and culm many new fine particles are generated during pyrolysis, most of which has a size smaller than 0.8mm. The primary fragmentation reaction of clarain and clum becomes severely with the increase of heating rate and the sample particle size. For durain particle, no obvious fragmentation is found under the same experimental condition. Factors, such as particle properties, particle size, furnace′s bed temperature and combustion time, have an important effect on the fragmentation of LY anthracite during its combustion in fluidized bed. Clarain and culm occur tremendous fragmentation in fluidized bed due to their compact structure, few large pores in inner particle, high microscope-hardness (H_ m,v ) and low ash content. The fragmentation of clarain and culm tends to be severely with the increase of particle size, bed temperature and combustion time. Durain doesn′t have obvious fragmentation during combustion in fluidized bed. Both clarain and culm undergo the secondary fragmentation during combustion, but the secondary fragmentation of clarain is severely in the late stage of combustion. The particle size of clarain declines more rapidly than that of culm. In the early stage of combustion, the mean particle size of clarain decreases promptly as a result of primary fragmentation, but with the time going it falls to a stable size. The combustion model of clarain in fluidized bed is equidensity shrinking core model, while that of durain is equidiameter one, and that of culm is a mixed model.

How this classification was reachedexpand
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.
