Fluidized bed thermal cleaning

About the technology...

At our Cegléd site we make thermal-based cleaning for metal parts with a specialized gas-powered fluidized bed oven. The Keppel SEGHERS fluid clean type furnace for paint stripping is a belgian made apparatus.

With this environment-friendly technology we can make iron-steel parts reusable.

Description of the cleaning technology

The metal parts containing organic materials are placed in a steel mesh basket, which is then submerged in a fluidised sand bed, in the operating space. Then this space is closed and heated with gas burners. The thermal decomposition of organic materials takes place when they make physical contact with the hot sand that has a temperature of approximately 450 °C. Through the process, the organic substances turn into gas and are partially incinerated.

Then, the gases are transferred from the operating space to the post-combustion chamber – that has a constant temperature of 750 °C – where the full and complete incineration of the organic materials takes place. The exhaust gases are discharged after being cooled down and the ceramic filter dust removal process. At the end of the cycle, the parts in the removed basket are clean and after cooling down, ready to be used again. The heat-treated parts can then be post-treated depending on the customer’s needs.
