Low-NOx gas calciner FCB Preca-Max®

As an inline rotary combustion chamber, the FCB Preca-Max® enables the processing of coarse solid alternative fuels. It is integrated in a preheating or calcining tower. It combines high flexibility with efficient thermal power distribution to maximize a cement plant’s alternative fuel substitution ratio. Fives develops solutions with our clients to ensure the best fit for each plant’s unique constraints. And because of the wide range of alternative fuels that can be used in cement production, each plant’s specific constraints must be considered in the equipment design. Our FCB Preca-Max® was designed to enable our clients in the cement industry to reduce their environmental footprint and costs, with optimum productivity. But more importantly, the solution is flexible and adaptable to a wide range of applications. Key benefits: 100% thermal substitution rate in the precalciner Significant cost savings thanks to reduced fuel preparation Low NOx and carbon emissions Robust design for limited maintenance needs Extended residence time ensures complete char combustion of large particles The FCB Preca-Max® is a rotary calciner that acts as the first part of an inline calciner in burning lines. The solution offers optimum flexibility and can be implemented on new clinker lines or on modernization projects. Key FEATURES: High flexibility in terms of fuel type: accepts tires, fluff, biomass, sewage sludge and other refuse-derived fuels (RDF), of up to 400 mm (16 in) in size Adjustable tertiary air distribution
