Abstract

Abstract To address the fouling problem in boilers fired with high-sodium coal (HSC), a composite ceramic coating was developed using the slurry method and applied on 15CrMo steel. After sintering, the composite ceramic coating had a dense structure and was well bonded to the substrate forming a metallurgical damascene structure. The fouling and thermal shock resistance of the ceramic coating to sodium sulfate was found be excellent. After five fouling cycles, the uncoated steel had a surface fouling rate of 21.9%, compared to 0% for the coated steel. The composite ceramic coating also demonstrated an appreciable fouling resistance to sodium sulfate. Similar to the flaky oxide film formed on the uncoated steel surface, only a few fine sodium sulfate particles penetrated the microcracks generated during the sintering of the ceramic coating. However, remarkable anti-fouling results were achieved when the composite ceramic coating was applied in an industrial boiler fired with a Zhundong HSC blend.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
