Gas Metal Melting Furnace is used to melt copper, gold, silver, copper, aluminum, zinc, tin and other metals with melting points below 1450 ° C(2642° F). Suitable for most fuels, liquefied gas，LPG, propane, etc. Many other people’s single burner furnace and dual burners at one side furnace have a problem, the flame can only heat one side of crucible strongly , the flame can only reach to 1/2 wall of the crucible, the opposite side has no flame. So we often saw that some part of metal in crucible has been melted, but some other part is not yet. It means you need longer time and more gas to melt whole pot of metal, my dual burner solved this problem by heating 2 sides of crucible at the same time, it can save 50% time and 20% gas cost. As we know, 40%–70% gas energy is actually escaping in heating process, that is a big waste . So if you melt fast, you save more propane cost.
