Lyophobicity and slagging resistance mechanism of h-BN based coating for coal-fired boilers
Abstract
Abstract Sodium reacts with sulfur oxide to form molten Na2SO4 during combustion of high-sodium coal (HSC). The resulting sticky inner layer captures ash to form slag, which inhibits heat transfer and flow of combustion gases. A novel water-based ceramic coating with hexagonal boron nitride (h-BN) as the main component has been recently developed to address the slagging problem in boilers that burn HSC. In the present study, wettability tests were performed to show that, compared with uncoated steel, the coating was completely lyophobic to molten Na2SO4. Density functional theory was used to study the adsorption of Na2SO4 on coated and uncoated steel at the atomic level. The calculated adsorption energies, electronic density of states, and Bader charges of Na atoms adsorbed on h-BN(0001) and Fe2O3(110), representing the coating and steel, respectively, indicated that the interaction of Na atoms with h-BN(0001) is significantly weaker than that with Fe2O3(110). Therefore, the ceramic coating could effectively inhibit the formation of the sticky inner layer composed mainly of Na2SO4 and alleviate the slagging of HSC-fired boilers.

In the citing paper
“The slag reduction by coatings is contributed by two mechanisms, which are (I) prevention of high temperature corrosion from slag deposits [144, 149, 150] and (II) reducing the wettability of molten fly ash on the coated surfaces [145, 147].”

In the citing paper
“The coated surface reduced the wettability of Na2SO4, resulting in a weakened ability of the initial sticky layer to capture fly ash particles and restrict the further formation of the slag deposits.”

In the citing paper
“The lyophobicity of such coatings was reflected by poor wettability of molten Na2SO4 droplets—an alkali salt to form the initial sticky layer—on the coated surface compared to uncoated metal.”

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.
