Fuel composition and method for extending the time between turbine washes when burning ash bearing fuel in a turbine
The addition of a magnesium compound to an ash bearing fuel results in a reduction in the formation of deposits in the turbine and extending the interval between turbine washes when burning the ash bearing fuel in a turbine compared to burning the ash bearing fuel in a turbine without the addition o...

| description | The addition of a magnesium compound to an ash bearing fuel results in a reduction in the formation of deposits in the turbine and extending the interval between turbine washes when burning the ash bearing fuel in a turbine compared to burning the ash bearing fuel in a turbine without the addition of a magnesium compound. The additive is desirably effective with ash bearing fuel having less than 0.5 ppm vanadium by weight, less than 1 ppm sodium and potassium combined by weight, and greater than about 25 ppm ash by weight or greater than 2 ppm calcium by weight. The additive is blended with the ash bearing fuel to give a mass ratio of magnesium to ash of between about 0.5 to 1 and about 3 to 1, and desirably about 1 to 1 on a mass basis after mixing. |
