Abstract

fetched live from OpenAlex

A techno-economic feasibility study has been conducted to investigate revamping two 32 MWe pulverized-coal (PC) boilers with circulating fluidized bed (CFB) firing. The steam generators at Panki Thermal Power Station in Kanpur, Uttar Pradesh, are owned by Uttar Pradesh Rajya Vidyut Utpadon Nigam Limited (UPRVUNL), supplied by Waagner Biro, Austria, and commissioned in 1967–68. The study reveals that: (i) CFB revamping of the boilers is technically feasible and economically viable; (ii) Performance improvement of the plant is significant in terms of such indices as plant load factor, forced outage and a 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) Significant improvement in emissions performance due to the reduction in emissions of NOx and fly ash is projected. (iv) The financial analysis indicates that the CFB revamping option gives the highest return on investment compared to alternatives. Finally, to demonstrate the technical soundness and viability of the special design used in this revamping a sub-scale CFB boiler has been design and built at another power plant.

Full frame distilled prediction

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.
