A strip curing oven apparatus for treating a workpiece carrying a coating containing a vaporizable solvent which is oxidizable to provide at least part of the heat requirement of said oven apparatus and which oven apparatus comprises an oven having a plurality of oven zones, such workpiece being movable through said oven zones in sequence, radiant header means disposed within one said oven zone so as to radiate heat toward a workpiece moving through that oven zone, incinerator means for incinerating oven gases to oxidize solvent vapors contained therein and to discharge such gases, after incineration, at an elevated temperature and with a reduced solvent vapor content, into said radiant header means, first gas-transferring means for transferring oven gases containing untreated solvent vapors from at least one of said oven zones to said incinerator means, oven gas circulation means located in said oven zone containing said radiant header means for circulating oven gases for passage between said radiant header means and an opposed surface of a workpiece moving through said oven, and, second gas transferring means for receiving incinerated gases from said radiant header means and for transferring and discharging such gases into a plurality of said zones of said oven. There is also disclosed a method of curing a coating on a strip workpiece.
