NOVELTY - Cooking range with twice gasifying-burning function and capable of"eating"minor cereals comprises furnace body, furnace upper cover, feeding port, sand sealing ring, flame passage, vertical furnace bar, primary air door, secondary air door, and third air door, where furnace body (1), furnace upper cover (2), vertical furnace bar (14), feeding port (3), sand sealing ring (9) are fixedly connected. Primary air door (19), secondary air door (11), and third air door (12) are adsorbed on furnace body (1). Locating ring (8) and sand sealing ring (9) are connected by labyrinth sand seal.    USE - The cooking range with twice gasifying-burning function is useful for"eating"minor cereals (claimed).    ADVANTAGE - The cooking range is adaptive to gasifying-burning of powder mineral or biomass fuel with great water-containing amount, non-unified size, complex shape and low thermal value, and the mixed gasifying-burning of mineral and biomass fuels. The cooking range with twice gasifying-burning function can gasify and burn animal carcasses or dejection and kitchen rubbish of leftovers; it also has strong adaptability so that it can"eat"minor cereals.    DETAILED DESCRIPTION - Cooking range with twice gasifying-burning function and capable of"eating"minor cereals comprises furnace body, furnace upper cover, feeding port, sand sealing ring, flame passage, vertical furnace bar, primary air door, secondary air door, and third air door, where the furnace body (1), furnace upper cover (2), vertical furnace bar (14), feeding port (3), sand sealing ring (9) are fixedly connected. The primary air door (19), secondary air door (11), and third air door (12) are adsorbed on the furnace body (1) by magnetic force and can be moved upwards, downwards, leftwards and rightwards. Flame passage outer pipe (6), boiler support (7) and locating ring (8) are fixedly connected and embedded deeply in the fuel. The locating ring (8) and the sand sealing ring (9) are connected by labyrinth sand seal. The feeding cover (4) and the feeding port (3) are also connected by labyrinth sand seal. The vertical furnace bar (14) is a secondary air supplying passage.    DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of a cooking range with twice gasifying-burning function.
