Based on extensive customer feedback, our factory has developed a new type of internal combustion carbonization furnace, that saves core fuel wood while achieving high-temperature dry-distillation charcoal production. Its carbonization process fully simulates the traditional earth kiln method.
Working Principle of the New Internal Combustion Carbonization Furnace
A square ignition port is located at the bottom of the furnace body.
After the furnace is fully loaded with wood and the door is closed, only a small amount of kindling wood is ignited at the ignition port, then the door is sealed again.

- Inner layer: high-temperature-resistant boiler steel plate
- Middle layer: thick thermal insulation cotton
- Outer layer: welded steel plate
All joints are sealed with graphite packing to ensure complete airtightness and no air leakage.

Exhaust gas and fumes are processed through pipes and discharged as white vapor, making it eco-friendly and fully compliant with environmental protection standards.
