Recycled fuels made from wood pulp and wood, and wood pellets, which are eco-friendly fuels, can achieve high thermal efficiency at a lower cost than other fossil raw materials, In addition, carbon emissions, which are harmful gases caused by combustion, are also exempted from carbon dioxide regulations by a factor of 1/12 compared with diesel fuel. Since they are supplied as homogeneous fuel, it is possible to control the supply amount accurately and it is easy to store and manage. The trend is gradually increasing. However, most non-powered pellet furnaces using pellets as a fuel use a downwardly-burning combustion structure and a cylindrical or box-shaped body having a combustion chamber formed simply inside. This is because it is difficult to regulate the thermal power by the simple dropping method due to the reverse flow of the flue gas, backlash due to the pelletization of the pellet supply pipe after the exhaustion of the pellet, and the simple structure of the body. There is a problem such as generation of smoke, and it is not easy to perform a function other than heating. In addition, as outdoor activities such as leisure and camping in the winter are increasing, demand for portable non-powered pellet stoves is also increasing, but it is not easy to buy pellets outdoors. Therefore, if the fuel pellet is exhausted or not ready, it is necessary to use a pellet fireplace combined with a harmonious wood that can be heated and changed by firewood or other fuel.
