Abstract
Initially coal-slurry fuels were based on coal-oil mixtures. Now the emphasis is largely on coal-water fuels. Since most of the studies have been done with coals available in the western countries having low ash content, an attempt has been made in this paper to study some aspects of the rheological behaviour of coal slurries prepared out of coals having high ash content. Crisis in the volatile oil markets experienced in the seventies have promoted renewed interest in coal-based fuel technologies. Coal-slurry fuels have emerged as viable technical alternatives for oil and gas in utility and industrial boilers. Despite current low prices and the abundance of oil, concerns over its long-term availability and price, as well as strategic considerations make coal-slurry technology attractive. In this paper an empirical relationship has been established among apparent viscosity and volume fraction of solids for coal having high ash content.

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
