The invention relates to an efficient heat-recovering and energy-saving stove. The efficient heat-recovering and energy-saving stove comprises a support, a cooking bench and a stove mouth; the top ofthe support and the surface of the bottom of the cooking bench are mutually welded; a material supply port is formed in the surface of the cooking bench; an air inlet is formed below the material supply port; a slag collecting cabin is arranged below the air inlet; the stove mouth is positioned on the surface of the top end of the cooking bench; a water tank is arranged on one side of the cookingbench; a smoke discharging pipe is welded and arranged at the bottom of the water tank; one end of the smoke discharging pipe is communicated with the water tank and the other end of the smoke discharging pipe is communicated with the cooking bench; a water inlet is formed in the upper part of the water tank and a water outlet is formed in the lower part of the water tank; a pipe plate in the water tank divides the water tank into a smoke inlet chamber, a heat change chamber and a smoke discharging chamber; the smoke inlet chamber is positioned at the bottom of the water tank; the heat exchange chamber is positioned on the middle part of the water tank; the smoke discharging chamber is arranged on the upper part of the water tank; and the smoke inlet chamber, the heat exchange chamber andthe smoke discharging chamber are communicated through smoke pipes. Heat energy generated by fuel is recycled completely, the combustion efficiency of the fuel is improved, the consumption of the fuelis reduced and the accident that a user is poisoned by carbon monoxide can be effectively avoided.
