(57) Some embodiments are directed to a method to avoid the negative effect of both sulphur and vanadium presence contained in solid fuel used in cement clinker manufacturing line (build-up, kiln rings, etc.). Some embodiments are methods to prepare, dose and use a fuel additive based on an alkaline earth metal to allow the combination of vanadium and sulphur with said added alkaline earth metal, so that corrosion, build-up, crusts and ring formation in cement pre-heaters and kilns due to the presence of those components are avoided.
