During the cleaning process the vanadium content in the boiler may be 0.032 to 0.048 gm. per cubic metre as dust in the air and in the gases up to about 0.015 gm. per cubic metre. In all the 7 regular boiler cleaners, vanadium bronchitis was diagnosed on several occasions. Case histories are included in the paper.Learn More
We report a case of subacute myopathy in a 47 years old man engaged on boiler maintenance at an oil-fired thermoelectric power station. The occupational history highlighted heavy exposure to inhalation of ash derived from mineral oil combustion and containing several elements, metals and metalloids, including vanadium and nickel. The presenting symptoms, clinical course and …Learn More
The deposits found in the gas passages of furnaces and boilers fired with residual petroleum fuels consist mainly of carbon, fuel-oil ash and sulphates. Carbon deposits may be minimized by attention to combustion conditions, and sulphates by eliminating any acid-dewpoint condition, but the ash (mainly vanadium and sodium) will accumulate as a Learn More

for the causation of vanadium poisoning, bronchitis, and related disorders (possibly even emphysema) in men engaged in the cleaning of oil-fired boilers. Since the soots of heavy residual fuel oils are quite commonly rich in vana-dium compounds (see section 2.5), the explanation of the source of the vanadium presents little difficulty. InLearn More

The facility operates four coal fired boiler u nits (units 1, 2, 4, and 5) and one nuclear unit (unit 3) at this location. Units 4 and 5 were the only units which were practicing NO x control and flue gas conditioning by ammonia injection; therefore, all fly ash collected came from these units.Learn More
