    Abstract: This invention relates to the inhibition of corrosion resulting from the presence of vanadium and sodium 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/Al/Si combinations thereto. Mg/Al/Si combinations are more effective than other inhibitors at a high Na/V ratio.

    Abstract: A cold end corrosion rate measuring probe consisting of a corrosion rate meter probe modified by the addition of a cooling jacket and a temperature measuring device such as a thermocouple. The probe is adapted to be flush mounted in an exhaust line or flue. A coolant, e.g. water, is circulated through the jacket to bring monitored gas to its dew point, at which point, a corrosion rate measurement can be made. The dew point may also be indicated by increased conductivity across two adjacent electrodes of the probe, e.g., the reference and test electrodes. Measurement of corrosion rate and accompanying dew point can be correlated with sulfur trioxide concentration in flue or exhaust gases and hence enables predictability of occurrence and location of "cold end" corrosion, which also indicates inhibitor effectiveness.

    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.
