{"product_id":"draagbare-smeltoven-20-kg","title":"Portable 20 kg gas melting furnace with 2 burners","description":"\u003cp\u003eThis portable melting furnace is built to melt up to 20 kg of brass and reaches a temperature of approximately 1,450 °C, or 2,642 °F, on propane. That lets you work with gold, silver, copper, aluminium, brass, bronze and tin, among others. The model comes as a complete set: you only need to supply a gas cylinder yourself.\u003c\/p\u003e\u003ch2\u003eBurner and air supply\u003c\/h2\u003e\u003cp\u003eThe furnace has two DFC burners with a combined output of 360,000 BTU. The nozzle is designed to last longer and to increase burner efficiency. The burners are made of 304 stainless steel.\u003c\/p\u003e\u003cp\u003eOn top of each burner is a choke that controls how much air mixes with the propane during combustion. This adjustable air supply is the feature to look for in a melting furnace. Without a choke you won't reach the maximum temperature, because every working pressure calls for a different air-to-gas ratio.\u003c\/p\u003e\u003cp\u003eThe burners are pre-set to a neutral flame, after which you fine-tune with the choke. The working pressure range is between 1 and 25 PSI. Fuel consumption is low.\u003c\/p\u003e\u003ch2\u003eFuel\u003c\/h2\u003e\u003cp\u003eThe burners run on butane, propane, a butane and propane mixture, and LPG.
