Abstract
A techno-economic feasibility study has been conducted to investigate revamping four 58 MWth (15 MWe) pulverized-coal (PC) boilers with circulating fluidized bed (CFB) firing. The steam generators at Amarkantak Thermal Power Station in Chachai, Madhya Pradesh, are owned by Madhya Pradesh State Electricity Board (MPSEB), supplied by Simmering-Graz-Pauker AG of Vienna, Austria, and commissioned in mid-1965. The study reveals that: (i) CFB revamping of the boilers is technically feasible and economically sound; (ii) Performance improvement of the plant is significant in terms of such indices as plant load factor, forced outage and auxiliary oil consumption, among others. The expected performance improvement is due in large part to the elimination of key outage-prone components such as pulverizers (mills) and burners. (iii) There is significant improvement in emissions performance due to the reduction in emissions of NOx and fly ash; (iv) The financial analysis indicates that the CFB revamping option gives the highest return on investment compared to alternatives.

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
