This formed a thin layer of MgO on the exposed furnace and convection surfaces and was found to significantly reduce SO3 formation probably by inhibiting the catalytic effect of these surfaces. The authors surmized that the layer of MgO would also beneficially influence high-temperature corrosion.
Il s’est formé une fine couche de MgO sur les surfaces exposées du foyer et de convection qui a eu pour effet de réduire sensiblement la formation de SO3, probablement en bloquant l’effet catalytique de ces surfaces.
