FLEXICAL™ FLEXICAL™ burners are customized to be used in preheaters and precalciners of clinker kilns. They translate the application of more than forty years of experience that Greco has in the field of combustion to meet local and specific conditions of the cement manufacturing process. FLEXICAL™ burners are efficient and can be used with any kind of fuel; their qualities assure excellent results in firing petcoke, solid and liquid wastes. FLEXICAL™ burners main features: • Reduction of CO emissions • Process stability because fuel is fired in the most appropriate region in the precalciner; • Coating forming control • Fuel is injected and fired on the most favorable position • Refractory life-cycle is increased • Simple installation • Easy maintenance

FLEXICAL™ burners are developed on a caseto-case basis to guarantee a full mixture of gas and fuel flows as well as the appropriate residence time. For this kind of development, Greco´s proprietary softwares are deployed – a result of decades of experience and continuous improvement in the combustion field – plus the support of CFD – Computational Fluid Dynamics. This is the reason why FLEXICAL™ burners are always the best solution for a mix of fuels that is going to be used, and for the type of precalciner or preheater where they will be placed. They are multi-fuel burners that are fit for...
