Method to reduce build-ups, crusts and ring formation in clinker production

A method of simultaneously capturing sulphur and vanadium from solid carbonaceous fuels-, wherein the solid carbonaceous fuels contain from 4.5% to 8% in weight of elemental sulphur and from 500 ppm to 5000 ppm of vanadium, the method comprising:

• preparing a fuel additive composition, the fuel additive composition including,
• 20%-60% (w/w) of solid active content of an oxide or hydroxide of an alkaline earth metal,
• 0.5%-5% (w/w) of solid active content of a suspension stabilizer, and
• 35%-79.5% (w/w) of a water miscible liquid;
• dosing the fuel additive prepared in the preparing step according to the formula,
• Additive Dosage (ml/min)=V2O5 (ppm)×Fuel Supply (ton/min)×A,
• wherein V2O5 (ppm) is the amount of V2O5 in ppm that is formed considering that all the elemental vanadium present in the fuel react with oxygen to form V2O5, and
• A is a factor ranging from 1.0 to 4.0;
• adding the fuel additive to the solid carbonaceous fuel;
• grinding the fuel additive together with the solid carbonaceous fuel;
• and
• feeding the mixture fuel-fuel additive into the preheater and/or kiln, according to the needs of the clinker manufacturing process.
