The invention discloses a particle steam energy-saving stove. The particle steam energy-saving stove comprises an energy-saving stove shell. A storage hopper is arranged at the top end of the energy-saving stove shell. A charging port is formed in the top end of the storage hopper, a feeding port is formed in the bottom face of the storage hopper, and a feeding pipe is arranged at the bottom end in the feeding port and is internally provided with a spiral feeding device. A stove body is fixedly arranged at the top end of a combustion chamber. A flue is arranged at the bottom end of the stove body. One side of the energy-saving stove shell is detachably provided with a draught fan, and the draught fan is connected with one end of an air inlet pipe. A water tank is fixedly arranged on the periphery of the combustion chamber and internally provided with a water level sensor and a water tank anti-explosion safety valve. The water level sensor is used for effectively controlling the water level, and the water tank anti-explosion safety valve is used for controlling the water tank pressure. Ash removing plugs are arranged at the two ends of the horizontal flue, a combustion chamber shellis provided with a residue removal door and a dust removal plate, and accordingly, the purposes that the storage hopper and the water tank are effectively protected, dismounting, mounting and repairing of the energy-saving stove are convenient, and chimney and combustion chamber ash cleaning is convenient are achieved.
