Some of the advantages of FLS Kiln Inlet Lamella Seals

• Extremely flexible Sealing between kiln and prehealer
• Independent of kiln rotation
• Insulation incorporated to protect the lamella spring effect
• Scoop arrangement included
• Rapid and easy maintenance
• High-rated, secure sealing effect
• Straightforward Installation even on non-FLS equipment
• 10,000 – 20,000 service hours for wear parts (dependent on the process conditions)

Kiln Inlet Lamella Seal

The FLS Kiln Inlet Lamella Seal is superior to the traditional  pneumatic seal because of its modern, rugged design and construction.
The inlet lamella seal consists of two sets of spring steel lamellae with a layer of heat-resistant fabric positioned between the two sets of lamellae. Between the inner and outer lamellae, a layer of heat-resistant fabric is positioned to protect the outer set of lamellae and enable them to maintain their resilience. This spring effect forces the inner set of lamellae against the cooling mantle and provides a seal.

To prevent overheating of the kiln shell and sealing parts, a separate fan delivers cooling air to the space between the kiln shell and the cooling mantle. It also supplies air to the cooling air chamber, which cools down the shell surface of the kiln riser transition piece.
If back spillage occurs, the scooping system (a system of open scoops made of heat-resistant steel) collects the spillage in the bottom of the scooping chamber and, as the kiln rotates, lifts it and returns it to the kiln. In the smoke chamber, the exit gases will suspend the spillage and carry it up into the kiln riser pipe.
