Because of the individual engine manufacturer views, we always recommend products for a customer's engine that fit within the specifications and operating philosophy of the engine manufacturer. Ash-bearing fuels, by definition, include any distillate, unrefined crude oil or residual oil containing sufficient quantities of ash to cause deposit and corrosion problems. Organometallic magnesium products such as SFA International's FuelSpec 130 Series products are normally recommended at levels of vanadium and lead up to 50 ppm. These additives are more complex and include combinations of magnesium, silicon and chromium.
Combustion Catalysts Several metals catalyze combustion of petroleum fuels.
These include iron, manganese, copper, barium and cerium. Iron is the best choice for combustion turbine applications. SFA International manufactures a ferric carboxylate salt unusually low in sodium and other trace metals. SFA International has had experience in the application of the iron combustion catalyst in several applications ranging from control of smoke during turbine start up to base load applications in fuels from high aliphatic waxy residual to high asphaltenic residual oil. Application of this product has enabled combustion turbine operators to continue operating engines in sites where tightened environmental regulations would require discontinuation of power production.
