Reduced Smoke Outdoor Fire Burner

摘要

A device for containing a camp fire reduces the amount of smoke produced by the fire. The device reduces the amount of smoke by supplying air to the top of the fire to increase the combustion and thus reduce the smoke produced. In one configuration of the device, the air supplied to the top of the tire is heated prior to being introduced to the top of the fire. The disclosure also provides a configuration wherein the preheating of the air simultaneously cools the outer surface of the device.
