The invention discloses a novel biomass energy-saving stove, and belongs to stoves. The novel biomass energy-saving stove comprises a stove body and a chimney, wherein the stove body is divided into a combustion region, a secondary combustion region and an ash storage region; an air inlet and an ash outlet are formed in the lower part of the stove body; a feeding opening is formed above the ash outlet; a fire bar is arranged between the ash storage region and the combustion region; a combustion-supporting body is arranged between the upper part of the combustion region and the secondary combustion region; and a plurality of air holes are formed surrounding the secondary combustion region. The novel biomass energy-saving stove is unique in design, solves the problem that a biomass stove is not full in combustion, saves energy, and is simple in structure and convenient to produce.
