Prenosni žar na drva iz nerjavečega jekla, zložljivi alkoholni zunanji štedilnik

Working principle: The ignition starts above the fuel, and the top fuel produces a layer of high-temperature carbon after combustion. This carbon heats the fuel below it, which is actually a process similar to dry distillation. The fuel below will mainly decompose into new carbon and some gaseous substances after being heated. This gaseous substance is wood gas, which is commonly known as smoke (this expression is not particularly accurate). After the wood gas is generated, it flows upward (hot air rises), passes through the high-temperature carbon layer above, comes into contact with the air, and burns to produce flames. This process continues until the bottom fuel, and finally the remaining charcoal in the furnace is burned. The filling fuel can be small wooden blocks, wood shavings or other debris, branches or leaves. The higher the energy density of the fuel you use, the longer the combustion time and output power will correspondingly increase. When filling fuel, try to fill the top layer with loose, dry, and flammable fuel as much as possible. This way, it is easier to quickly generate a high-temperature carbon on the surface to facilitate further reactions. This new type of firewood stove is a best-selling product and is highly sought after by both new and old backpackers at home and abroad. This firewood stove does not require continuous addition of firewood. The fuel inside the stove is converted and burned, and the fuel has a long usage time and high firepower.
