摘要
The solvent is oxidisable to provide at least part of the heat input requirement for the oven with several zones. The workpiece is movable through the zones in sequence. A gas circulation device circulates gases continuously around the workpiece and a gas input at each zone continuously introducing gas. There is a gas exhaust at each zone for continuously removing a portion of the atmosphere and a gas-transferring device is connected between the gas exhaust of a downstream zone. The gas input of an upstream zone transfers gases exhausted from the downstream zone and introduces them into the upstream zone. An incinerator at the upstream zone oxidises solvent vapour contained within the gases exhausted from the downstream zone on introduction into the upstream zone.
