![]() To fill an oil lantern, unscrew the fuel cap and pour in oil lamp oil. See our list of approved lantern oils for use inside and outside. With no air recycling and plenty of fresh oxygen to feed the flame, the cold-blast design achieved the most efficient process of combustion with the brightest and most stable flame. The cold-blast design sucks in more fresh air from around the globe and lantern top and channels it through the side tubes to the flame where all of the spent air is released. ![]() The invention of hot-blast lamps allowed for a brighter and more stable flame. This design takes hot air from just above the globe and channels it through the side tubes to the flame where some of the spent air is recirculated through the tubes. The hot-blast design was invented by John Irwin with a JanuPatent. This allows for complete combustion that carries more oxygen past the flame for a steady smoke-free light that's brighter than an open flame.īoth hot and cold blast lanterns are tubular designs when they get knocked over oxygen is cut off to the burner and the flame is extinguished. ![]() Creating a tight connection between the chimney and burner is known as making a "throat". Airflow to the wick is controlled through burner vents and the open chimney. Dead-flame lamps have a fuel tank (fount) that attaches to a wick-holding lamp burner with four prongs to hold the glass chimney enhancing the thermal draft and preventing the flame from being blown out. If the lamp breaks the design can easily start fires. Flat wick lamps and lanterns are designed for portable use are made in three varieties: dead-flame, hot-blast and cold-blast.ĭead-flame is the most simple type of kerosene lamp that burns fuel by drawing it up through a wick. We want to help you safely use and operate oil lanterns so they are more than useless decorations.
