<p>PURPOSE: A copper reducing device using LPG with improved safety and workability is provided to guide bubbling by injecting LPG to a melting furnace using high-pressure. CONSTITUTION: A copper reducing device using LPG with improved safety and workability is composed of a melting furnace, a flame forming unit, and an LPG feeding unit. The LPG feeding unit is composed of LPG storage units(31), regulators(32), transferring lines(33), and injection units(34). The transferring lines are composed of ascending pipes(331), descending pipes(332), connection pipes(333), and couplings(334). The ascending pipes ascend transferred gas. The descending pipes descend the ascended gas. The connection pipes connect the ascending and descending pipes.</p> |
