Abstract

Coil coating process, comprising thermally curing the coating of an endless strip by means of near infrared radiation in a curing oven provided with near infrared emitters and the subsequent destruction of volatile solvents contained in exhaust air of the curing oven by means of thermal oxidizing same in an oxidizer chamber, wherein heat introduced into the solvent within the curing step is used in the oxidizing step, wherein air serving as coolant for the near infrared emitters is fed into the curing oven in a pre-heated state, exhausted from the curing oven loaded with the volatile solvents and guided through a heat exchanger for further heating the exhaust air by means of heat exchange with purified hot air exiting the oxidizer chamber, before introducing the exhaust air into the oxidizer chamber.
