  • Vanadium Bronchitis from cleaning Oil-Fired Boilers.

    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

  • Toxic myopathy induced by industrial minerals oils

    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

  • Fired Furnace - an overview | ScienceDirect Topics

    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
