Experimental Research and Microscopic Mechanism Analysis on Simultaneous Mercury Removal by Novel Integrated Semi-dry Desulfurization Systems
Bibliographic record
Abstract
Coal,slag,and fly ash samples were taken from a utility boiler equipped with the NID(Novel Integrated Desulfurization) system,and the mercury contents of these samples were measured.Ontario-Hydro method was applied to determine the mercury patterns in flue gas before and after NID system.The physicochemical characteristics of the ashes in NID system were analyzed by specific surface and porosity analyzer,X ray diffractometer,scanning electron microscope and spectrometer,and the microscopic mechanism of simultaneous mercury removal by the novel integrated semi-dry desulfurization system was revealed.Results indicate that the lime hydrate and quick lime can mix thoroughly in the novel integrated semi-dry desulfurization system and the circulation ratio of fly ash in the desulfurization tower is high.There is always fresh Ca(OH)_2 on the surface of the mixture ash.Furthermore calcium silicate hydrate is formed in the desulfurization tower and particle agglomeration is serious,which is very beneficial for SO_2 and mercury removal from the flue gas.The mercury removal efficiency of the novel integrated semi-dry desulfurization system for flue gas is as high as 86.6%~92.2%,and the control effect for mercury emission of the coal-fired power station is obvious.

How this classification was reachedexpand
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.
