Sulfur as a Fuel Source in a Combined Power Cycle Equipped with a Dry Flue Gas Desulfurization System
Bibliographic record
Abstract
This paper investigates the novel use of elemental sulfur as a fuel in a combined cycle power plant, wherein sulfur is oxidized in the combustion chamber to produce work from a gas turbine. Produced sulfur dioxide is then reacted with calcite to produce anhydrite (CaSO 4 ) in a flue gas desulfurization unit. The desulfurization reaction is exothermic, producing heat that can be converted to electricity by passing the exhaust gas through a heat recovery steam generator. The cases studied in this work are a 410 MW natural gas combined cycle, used as a reference case, a sulfur combined cycle (SCC) consisting of a typical industrial gas turbine with heat recovery followed by desulfurization, and a third case of a SCC followed by desulfurization before the heat recovery, thereby producing power from the exothermic desulfurization reaction. Energy calculations of the last case show promising results for converting sulfur to anhydrite through a combined cycle that produces 615 MW of electrical power with CO 2 emission of 0.584 kg/kWh, a value lower than the representative value of a new, supercritical coal power plant.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
