The utility model provides an energy-saving
firewood stove structure, and belongs to the technical field of
firewood stoves. Comprising a fixing plate, a conical furnace chamber is fixed to the upper portion of the fixing plate, an annular
flue plate is fixedly connected to the edge of the conical furnace chamber, the annular
flue plate is coaxially sleeved with an inner-layer protective cover, the inner-layer protective cover is coaxially sleeved with an outer-layer protective cover, and the upper portions and the lower portions of the inner-layer protective cover and the outer-layer protective cover are fixedly connected with the annular
flue plate. An annular flue is formed by an annular cavity between the annular flue plate and the inner-layer protective cover, the annular cavity between the inner-layer protective cover and the outer-layer protective cover is filled with a first heat
insulation layer, and a second heat
insulation layer is arranged on the upper portion of the annular flue. By means of the annular flue and the porous structure,
smoke and fire enter the annular flue in a dispersed mode, heat does not enter the
smoke pipe in the first time, the generated heat is reutilized, and
firewood or
coal is saved by 20%-40%; and two heat insulation
layers are additionally arranged, so that heat is effectively prevented from being diffused outwards, and the purposes of saving energy and recycling are achieved.
