NOVELTY - The stove has a stove body divided into a material storage chamber (1), a combustion chamber (2) and a smoke channel area (11). A front counter heating board (3) is arranged between the storage and combustion chambers. A lower part of a material storage chamber cover (15) is provided with a grate (6) and an ash bucket (16). A rear counter heating board (8) is arranged between the combustion chamber and a flue gas passage zone. A flue gas channel is connected with an air guide pipe, which is connected with a combustion zone. Flame and outer oxygen make complete combustion process.    USE - Three-return stroke counter-heating type biomass superconducting heat semi-gasification stove for use during cooking process in a home.    ADVANTAGE - The stove is environment-friendly, and has better heating effect, and ensures that a traverse baffle heat absorbing plate is arranged at a large heating surface area through a furnace body water sleeve, thus saving energy for about 60 percent. The stove utilizes up and down air flowing technique, so that the oxygen is completely utilized for reversely burning a flame downlink through a counter heating board after heating process, thus making the smoke in a volatile component to be fully combusted to form bright yellow flame with high temperature. The stove ensures that two baffles are orderly arranged in the flue gas baffle heat absorbing plate without utilizing smoke chimney and the smoke is discharged from the chimney. The chimney is equipped with a heat superconducting pipe, thus absorbing surplus heat and reducing heat energy wastage. The stove is simple and quick to operate, and switches to directly heating and cooking functions. The stove allows the fuel to be utilized in different biomass pressure block, bituminous coal and anthracite.
