Radiant heating apparatus for curing coated strip material

摘要

A coating containing a vaporizable solvent on a strip passing through an oven apparatus is dried or cured at least in part by means of a radiant heater disposed within such an oven apparatus. Solvent-carrying gases are removed from the oven and incinerated to oxidize the solvent vapors contained therein and to provide gases at an elevated temperature and with a reduced solvent vapor content. Such heated gases are then passed through the radiant heater which receives heat from such gases and radiates heat toward the strip. Optionally, openings are provided in the radiant heater to allow for the flow of hot gases from within the radiant heater through such openings for impingement on and direct heating of the strip.
