1991: Paper "Energy saving and emission reducing impregnation technique"

In the issue 6/1991 of the german trade journal "farbe + lack", the implementation of an economic, energy saving impregnation plant with a thermal post-burning unit is described and a performance balance is given. This article is available on request.


When electric coils (transformers, ballasts, motors) are impregnated with unsaturated polyester resins, styrene is emitted. in common impregnating plants, high air flow rates needed for waste air treatment cause high energy consumption. Using teh EEC-technique, flow rates are reduced, controlled and re-circulated. This allows a self-preserving, energy saving thermal post-combustion, which adapts itself to the incurrend emission. The surplus of energy set free when burning the used solvent is re-circulated into the process.
