Experimental Investigation on Influence of Injection Angle of Burners on Aerodynamical Field in W Shaped Flame Boiler
Bibliographic record
Abstract
Cool state experimental investigation has been made in a model of the 360 MW W shaped flame boiler,measuring flow field in the boiler with a hot wire anemometer,and studies of regularity on influence of injection angle of burners on aerodynamical field in boiler is made in this paper.It is manifested that the action of prima air and secondary air washing out front and rear walls (water cooling walls) of furnace can b dropped evidently,meantime,the scouring velocity and angle of high temperature gas against throat,front and rear arches of chamber of furnace can also be decreased along with the decrease of injection angle of burners,so that high temperature corrosion of water cooling walls can be efficiently protected and the degree of clinker in these positions can be alleviated.But the gas downward route in the chamber of furnace shall be shortened,this isnt beneficial to complete combustion of pulverized coal injected into chamber of furnace.

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.
