Abstract
A high-temperature, non-catalytic, infrared heater is formed within a housing having a bottom and at least one side lined with a refractory material. The burner includes a burner surface area and is positioned within the housing. A re-radiating surface is positioned above the burner and comprises a mesh having a re-radiating surface area greater than the burner surface area with the re-radiating surface operating between approximately 400° F. and 2200°F.
Claims4
A method for thermoforming plastic sheet using a high-temperature, non-catalytic, infrared heater comprising the steps of:
- providing a housing adjacent the plastic sheet;
- positioning a burner within the housing, the burner having a natural gas supply and a burner surface area;
- operating the burner between approximately 1400° F. and 2200° F.;
- positioning a re-radiating surface above the burner, the re-radiating surface having a re-radiating surface area;
- and
- sizing the re-radiating surface area greater than the burner surface area to operate the re-radiating surface at a desired temperature.
