In the middle of the coil, our Best 2 burer stove for outdoor life is a stove burning, put the pot on the cooker for cooking, and put a heat board under it to reduce the heat energy. Since the exhaust gas after combustion has a large amount of heat, the heat will heat the copper foil, and the incoming fresh air is heated by heat exchange.
The Best 2 burer stove for outdoor life is a double spiral ring made up of a set of copper foil. It has two interlayers, one of which passes from the outside to the inside to enter the stove to help combustion, and the other layer is exhausted from the inside to the outside. There are two miniature hair dryers on either side of the double solenoid, one blowing inward and the other blowing outward. When the cooker is heating the bottom of the pan, fresh air is required to enter continuously, and oxygen assists the combustion. When the middle of the coil is cooled by heat, the fresh air is changed from cold to hot, and the temperature of the cold fresh air entering the furnace is close to the high temperature when the exhaust gas just leaves the furnace, so the thermal efficiency is particularly high.
