Abstract: This invention generally refers to a new generation of fuel additives which can provide catalytic action to improve the combustion process of fossil fuels and to a catalyst among others containing an iron compound combined with an over-based magnesium compound with molecular size particles inside the combustion chamber. Such fuel additive catalysts are particularly useful for fuel oil combustion, natural gas combustion, stationary gas turbines, natural gas-fired reciprocating engines, diesel engines, gasoline engines and all stationary dual-fuel engines.

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.

Abstract: This invention relates to the inhibition of lead corrosion in fuel, for example, in residual fuels, such as in those fuels used in steam boilers and gas turbines, by adding certain metals thereto such as magnesium, calcium, aluminum, silicon, and combinations thereof.
