The intention is to use the high melting point inert materials in inhibitors to mix in the growing sediment, by intermittently spraying the powdery substance to flue gas on the upstream of heating surface.
The inhibitor used in this research is white powder mixture with a particle size about 74um, the main components of the inhibitor is high melting point MgO, supplemented by a small amount of CaCO3and other inorganic materials.
This reflects the presence of rock ore as common boiler bed material component.
