Product Overview
Overseas buyers use several names for this equipment. Batch burn-off oven is common for removing paint and powder coating from hooks, racks and fixtures. Pyrolysis cleaning oven and thermal cleaning furnace are also used when the application includes polymer or resin residues on metal tooling.
This is a gas-fired batch design with a large front-opening chamber and wheeled loading cart. Its purpose is to reduce manual scraping and chemical stripping for suitable heat-resistant parts while controlling the decomposition and exhaust-treatment stages in one equipment package.

How the Burn-Off Oven Works
Suitable coated workpieces are placed on the loading cart and moved into the primary chamber. The first burner heats the insulated chamber so the organic coating gradually decomposes into gas and carbon-rich residue. Process control is important because the rate and concentration of the decomposition gas must remain within the designed operating range.
The generated gas then moves into the secondary combustion chamber. According to the supplied process description, a second burner treats it in an oxygen-rich environment at approximately 650-900 C, converting the combustible fraction mainly into carbon dioxide and water vapor before discharge through the engineered exhaust path.
The two combustion systems are automatically managed by the electrical controls, while an automatic water-spray system is described as another way to control the decomposition rate and gas concentration. After shutdown and cooling, the remaining inorganic powder or ash can be removed by light mechanical cleaning or water washing where appropriate.

Application and Safety Notice
Thermal cleaning is not suitable for every part or contaminant. The part material must tolerate the selected process temperature, and seals, closed cavities, pressure-retaining spaces and temperature-sensitive components require review.
Do not load uncured resin, sealed workpieces, unknown chemicals, explosive materials or other easily ignited items without a formal process and safety assessment. Halogenated polymers and coatings can produce corrosive or hazardous decomposition products and may require a different cleaning technology or dedicated exhaust treatment.
