<p>FUEL COMPOSITIONS USEFUL FOR GAS TURBINES AND PROCESS FOR THE COMBUSTION OF SUCH FUEL COMPOSITIONS Gas turbine fuels, either ash-containing fuels having a high alkali metal content, such as greater than 5 ppm by weight sodium and/or potassium, or substantially ash-free fuels which are burned or combusted under conditions that alkali metal appears in the combustion products, are advantageously combusted in the presence of additive components consisting essentially of compounds of silicon and magnesium which form SiO2 and MgO at fuel combustion temperatures, the proportions of said compounds being such as to provide a combined SiO2 and MgO equivalent wherein the SiO2:MgO ratio is greater than 2:1, the quantity of said additive components present during the ' combustion of said fuel being such as to provide a magnesium to vanadium weight ratio of at least 2:1 and a weight ratio of silicon to alkali metal of at least 2:1, preferably greater than 6:1.</p> |
