<p>PROBLEM TO BE SOLVED: To provide a processor which can reuse even cracked gas, safely as energy. SOLUTION: In condition that a vacuum furnace lead recovering retort 12 is placed on a recovery receiving pan 11, the second sealed space 13 within a retort storage 9 is purged with N2 gas into oxygen free state. Then, a flame is jetted upward within heating space 2, by means of a heating burner 7 which uses, as combustion gas, the mixed gas being made by mixing uncombusted gas arising from cracked gas and city gas. As a result, the lead adhering to the vacuum furnace lead recovery retort 12 arranged within sealed space 13 fuses, and flows down into the lead recovery receiving pan 11.</p> |
