Title: Removal device for paint from metal items - delivers retort fumes to after-burner chamber via solids filter
Inventor: SCHWING EWALD
IPC: F23G5/027
Filed: 1991-08-23
Abstract: The equipment removes paint from sheet-metal and other metal items, particularly components of old cars, using a retort in which a gas current supports the fluidised bed, and into which the items are delivered. Fumes generated by paint removal are extracted from the retort and delivered into an after-burner chambr, containing a burner and preceded by a combustion chamber.
