The present invention is relates to a firewood stove using wood as a fuel, obtaining heat efficiency with less fuel consumption. An empty space with a separation wall is formed on a lower part of a flue duct to obtain an effect of preventing a backflow of smoke through resistance by atmospheric pressure. Moreover, heat retention is extended. According to the present invention, a stove and the flue duct are formed as one structure, and the stove side of a smoke discharge opening is narrower, and a flue duct contact part thereof is larger, thereby additionally retaining heat and improving its distribution. The flue duct and the stove are coupled to form one structure of a curved part and a branched part to decrease the speed of discharging and distributing the heat, thereby saving fuel and obtaining more heat efficiency. A heat deformation preventing frame is attached to a fuel intake where the fuel is injected to be connected to a fire door of the stove. A operational principle of a cam having a small deviation with respect to a center axis of two small circular plates is applied such that the fire door is compressed to be locked. Furthermore, an upper plate of the stove has a cooking grill to be used for cooking in addition to heating. Moreover, the stove produces healthy heat through the emission of far-infrared radiation in such a manner where far-infrared radiation material is heated on the lateral surface part of the stove. |
