Kiln Seal Repairs
Our kiln seals are designed to reduce your energy consumption and increase your process output. Our overlapping leaf seal designs successfully address the three major factors that cause premature seal failure:
- Radial run-out of shell at hood due to deformation of shell/cowl surface.
- Axial growth or position change of shell due to thermal expansion, load changes and thrust bearing/tire wear or adjustment.
- Abrasion of shell or seal components due to accumulation of spillage material from the end hood.
Using a seal manufactured by NAK Kiln Services eliminates the effect of radial run-out of the shell or cowl by the installation of a quadrant ring and seal riding plate. The riding plate becomes the actual sealing surface (the contact area of the pressure leaves) and is designed to be parallel to the kiln axis as determined by the tire and trunnions. Seal leaves are designed to accept axial movement of the riding band. Material accumulation in the hood is contained in the spill hopper. Accumulations are then removed before they can interfere with the pressure leaves' contact with the seal riding plate.
