  • Inhibition of corrosion in fuels with Mg/Si/Mn combinations
    Patent number: 4047875
    Abstract: This invention relates to the inhibition of corrosion in fuels, for example, in residual fuels, such as in those fuels used in steam boilers, process heaters and gas turbines, etc., by adding Mg/Si/Mn combinations thereto. Mg/Si/Mn combinations are not only very effective in inhibiting both corrosion and slag at high Na/V ratios but also produce other benefits including the reduction in smoke emissions when the fuel is combusted at improper fuel/air ratios.
