This thermal cleaning technique has found its application for already a number of years in a multiple number of industries and is mainly known as an efficient technique for paint stripping through refining this technology. It has become possible through refining this technology to use the pyrolysis oven for elimation of bigger amounts of contamination with specific thermal properties (for instance specific polymers)
During the pyrolysis process – which will take place under anoxic conditions (max +/- 9 %) – and at temperatures between +390°C and +450°C, organic materials will be decomposed into smaller components. This decomposition results in the formation of pyrolysis gases which are partially converted in water and CO2 vapor. The energy produced is then used in a further cracking process of the remaining organic components. The remainder of pyrolysis gases is finally incinerated at temperatures between 800 C and 1000 C to accurately control the emission process.
A standard pyrolysis process will take approximately 12 hours (including heating and cooling down time) but can be prolonged in function of the quantity and/or the nature of the contamination. By simultaneously using a number of thermocouples the temperature of the parts can be registered exactly during the pyrolysis process in order to control the allowed maximum temperature of the parts.
