Abstract
A tunnel kiln consisting of a succession of tunnel sections assembled from prefabricated large-surface side panels and ceiling panels supported on a tunnel frame of structural steel, at least some of the panels being removable for access to the kiln. Similar panels mounted on railcars form the bottom portion of the kiln. The panels are composed of multiple layers of different materials, the material and thickness of the surface layers being adapted to different heat resistance requirements, while the overall dimensions of the composite panels remain the same.
Claims16
A structure for a tunnel kiln enclosure of substantially rectangular interior cross-sectional outline, especially a kiln for the firing of ceramic objects on a production line basis, under continuous or intermittent motion, the tunnel kiln structure comprising in combination:
- a tunnel frame of structural steel extending the length of the tunnel kiln and including upright frame sections on both sides thereof;
- a plurality of longitudinally adjoining tunnel kiln sections, each of said kiln sections including a unitary prefabricated heat resistant ceiling panel extending transversely over the entire width of the kiln enclosure and being supported by said upright frame sections, and a similar unitary prefabricated heat resistant side panel on each side of the kiln extending over the entire height of the kiln enclosure, the side panels being likewise supported on said upright frame sections;
- a plurality of longitudinally adjoining rail cars carrying thereon similar unitary prefabricated heat resistant bottom panels which form a movable bottom for the tunnel kiln enclosure;
- and
- guide rails supporting the rail cars, the rails being mounted in parallel alignment with the tunnel frame.
