Recommendation from the Scientific Committee for

Pistelli et al. (1991) studied 11 vanadium-exposed workers 40-60 h after they had removed ashes from boilers of an oil-fired power station. Urinary vanadium concentrations were determined by AAS and ranged between 1.4 and 27 µg/l in the exposed group. Four of the Controls had also measurable concentrations of vanadium in the urine (range, 0.5-1.0

Fireside Corrosion | Chemistry Engineer Key

Aug 11, 2021 · Fuels containing vanadium, such as fuel oil, often used in the start‐up process in boilers, provide an even more effective catalyst for SO 3 formation. SO 3 readily dissolves in the molten sulfate, forming essentially pyrosulfate ions [S 2 O 7 ] 2− : SO 3 and O 2 are the main oxidants and SO 2 is insoluble in sulfate melts.

Understanding Refractory Failure—A New Perspective

Refractory has always been an integral part of steam-generating boilers. In the steam-generating industry, refractory materials are used for filling gaps and openings to help keep the fire inside the fire box, for lining ash hoppers (wet and dry) that collect ash and slag, and for the protection of lower furnace wall tubes inside fluidized bed, cyclone-fired, or refuse-derived fired boilers.
