Gas Metal Melting Furnace is used to melt copper, brass,gold, silver,aluminum, zinc, tin and other metals with melting points below 1300 ° C（2372 ° F）. Suitable for most fuels, liquefied gas，LPG, propane, etc. But it can not melt steel, iron.
Many other people’s single burner furnace has a problem, the flame can only heat one side of crucible strongly ,especially if you use a big size crucible, the flame can only reach to 1/3 or 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 big waste . So if you melt fast, you save more propane cost.
Package come with all of items in my 1st photo,including 2 burners, 2 regulators, 25 KG crucible, gloves,fire brick,hose & clamps,instruction manual. Besides, you need to buy a 25 kg crucible lifting and pouring tongs at below webpage: https://www.ebay.com/itm/295031215117

3. Outside Dimensions : 13.8″ diameter x 16.5″ height (35cm x 42cm);
4. Inner Dimensions: 9.8″ diameter x 11.8″Height (25cm x 30cm);

Our special advantage:
1. Dual burner can save 50% time and 20% gas cost.
2.The air choke on our burner can control the air and flame at different gas pressure.
3. Many other seller’s burner head may be melted damaged after long time using in high temperature flame ,so you had to change the whole burner. But our bell shape burner head can be changed because it is connected by thread, you can buy replacement in local shop cheap and easily .
4. You also can use only one burner by shut off the valve ,and block one hole on furnace body with my additional ceramic wool.
