Lower furnace core 11 and upper furnace core 21 put into firewood and just level the first discharge port 202 and the second discharge port 203, put into a piece of solid alcohol, and light with an ignition gun. Add tap water to the water tank 207, turn on the blower fan knob gently, adjust the wind power, observe the influence of the wind on the firepower, until all the firewood is ignited, put the pot and cook. If it is pellet fuel, the working principle is the same.

When working, when the fan inputs oxygen from the air inlet 104, the oxygen is heated by the heat of the lower furnace core 11, and then the oxygen enters the lower combustion chamber 101 through the air inlet 102 (the lower furnace core 11 and the lower furnace jacket 12 are a closed space) , the firewood burned in the lower combustion chamber 101 encounters the strong oxygen heated by the fan from the air inlet 104, gasifies and burns rapidly, and the unburned combustible gas rises, and then encounters the lower furnace core 11 and enters the heating from the air inlet 102 Strong oxygen mixture to support combustion. All the firewood is gasified and burned, and the heat energy released by the firewood combustion reaches the pot body through the upper furnace core 21, and conducts heat transfer with the pot body, thereby heating the pot body and cooking the food in the pot.

When the exhaust gas, carbon particles, dust and sparks produced after the combustion of the upper combustion chamber 201, a part is discharged to the water in the water tank 207 by the flue 25, and the other part directly falls into the water in the water tank 207 through the hole on the baffle plate 23.
