Pyrolysis kiln FCB Kiln

The FCB Kiln can be supplied with 2 or 3 supports, with a girth gear or a friction drive. The efficiency of the FCB Kiln is improved by the tyres design and the upstream & downstream seals. The FCB Kiln is a long lasting equipment with some exceptional references: the largest one ever built in Belgium in 1975, with a size Dia. 7.1 x 227 m, is still in operation. Customer Benefits With a low clearance in operation, floating shims is a simple technique which ensures a long life of the refractory lining and requires easy maintenance. The roller station benefits from a trouble-free oil lubrication system. The moulded end parts of downstream seal can last several years. All seals (downstream and upstream) can be supplied separately. Technical Advantages Floating shims are machined to minimize stress and wear. Sturdiness and good behaviour of the roller station are ensured by the swivelling of the bearings and the use of Main Metall® bushings allowing high pressures. A sturdy thrust roller operates a scanning movement of the kiln which equalizes the wear of the roller. The newest experience demonstrates that the kiln outlet seal refractories can withstand severe conditions more than one year without repair. A patented system with embedded fans and no scales is also offered as an alternative. The heat-protected jacks of upstream seal compensate the kiln movements and ensure a perfect tightness.
