Fives’ proprietary equipment for burning lines includes the FCB Preheater, which increases the thermal efficiency of burning lines by reducing the heat lost in pyroprocessing. The unit is built within a concrete or a steel structure. It uses a single string for small to medium capacities of up to 5,000 tpd, and a double branch for larger capacities. Gases can be cooled with water atomization in the downcomer. The FCB Preheater’s main benefits: High heat efficiency (up to 97% settling efficiency) Low pressure drop (less than 50 mbar, including for stage 5 preheaters) High energy efficiency Reduced dust load in filters Key features: Designed to achieve a very low pressure drop Large cone to avoid build-up Reduced fan power consumption Efficient splash boxes and tilt valves to ensure stability, even at reduced production rates Lower cyclones equipped with segmented dip tubes to better resist chemical corrosion at high temperatures. Fives has a history of designing exceptionally long-lasting rotary kilns. One of the world’s largest kilns, built by Fives in Belgium in 1975, is still in operation today. Our units are also designed for optimized efficiency, thanks to advanced tire design and upstream and downstream seals. The kiln can be delivered with two or three supports, with a kiln girth gear or a friction drive. Main customer benefits of the FCB Kiln: Floating shims for low-clearance operations extend the life of refractory linings and are easy to maintain The roller station features a trouble-free oil lubrication system The molded end parts of the downstream seal can last for several years All downstream and upstream seals can be supplied separately
