This device is hydrogen reduction fireplace. A vacuum exhausts the inside of the fireplace heart pipe. H₂ is put after that. Heat-treatment can be done in the H₂ gas atmosphere.
- A vacuum can exhaust the inside of the fireplace heart pipe.
- Equality heat improves in the fireplace because heater control is done in 4 zone.
- The exhaust of H? is made to burn by the heater, and it is the structure that H? isn't released in the atmosphere.
