Abstract
In the modular kiln, which is designed for the firing of ceramic tiles etc., one has a series of single treatment zones (16) arranged in a continuous succession and interconnected by a conveyor (6); heat exchange is brought about by radiation between special surfaces built into the various zones of the kiln, and the material being fired.
Claims20
A kiln for heat treating materials such as tiles, comprising:
- a plurality of heat treatment zones arranged in succession, at least one of said zones including a means for heating;
- a conveyor means for transferring a material which is to be heat treated from one heat treatment zone to another;
- and,
- a means for transmitting thermal energy in each of said heat treatment zones from a respective one of said means for heating, said means for transmitting comprising at least one non-porous panel having a heat radiating face directed at said conveyor means, said means for transmitting allowing only a radiant transfer of thermal energy to the material which is to be heat treated.

An apparatus for heat treating materials, comprising:
- a furnace including a plurality of heat treatment zones arranged in succession, at least one of said zones including a heater;
- a conveyor means for transferring a material that is to be heat treated through said furnace;
- and,
- a plurality of non-permeable panels which are interposed between said conveyor means and said heater, said panels being positioned in an edge-to-edge relationship so as to isolate said heater from the material being heat treated and allow only a radiant transfer of thermal energy, wherein one face of each panel serves as a heat radiating surface.
1 more element
A kiln for firing ceramic materials such as tiles, comprising:
- a plurality of heat treatment zones arranged in succession and communicating freely with one another;
- a conveyor means for transferring a ceramic material to be heat treated through said plurality of heat treatment zones;
- a burner for providing heat in at least one of said heat treatment zones;
- and,
- a non-porous wall interposed between said burner and said conveyor means to prevent combustion gases from said burner from contacting the ceramic material to be heat treated, said wall assuring that all heat transfer to the ceramic material from said burner takes place by radiation.
