Advancing Industrial Smokeless Flaring: Experimental Study into a Swirl Air-Assist Burner
Bibliographic record
Abstract
The performance of a prototype swirl air-assist burner, designed to suppress flame thermal radiation and improve flame stability in crosswinds for industrial smokeless flaring, was experimentally investigated.The burner features a central swirl core shaped like a diffuser, equipped with tangential swirl blades to promote mixing between fuel and air.It was tested using vapour propane at assistair-to-fuel ratios (AAFRs) ranging from about 29 to 80, which gradually led to the formation of a central recirculation region.Visible flame characteristics were recorded with a video camera, while thermal radiation properties-including emissive power and emissivitywere measured using an infrared camera.Increasing the AAFR reduced the flame's height-to-width ratio, thereby enhancing flame stability under crosswind conditions.Smoke production also diminished, transitioning from a heavily smoky flame to a cleaner one.As the AAFR increased from 0 to its maximum value, the flame area (m) and emissive power (W/m) decreased by 69% and 24%, respectively.Overall, the experimental results confirm the suitability of this swirl air-assist burner design for industrial smokeless flaring, demonstrating improved performance in stabilizing the flame under crosswind conditions.

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.
