NOVELTY - An energy-saving, environment-friendly straw gasification furnace comprises an internal cylinder (5), an external cylinder (7), a swaging bar (12), a charging mouth sealed cover (1), an O-type sealed ring (14), a swaging mechanism (6), a spring (13), a blowing device (11), an air inlet pipe (8), an exhaust opening (15), and a sealed cover tightening clip; where the furnace further comprises a filter sheet (17), a swaging handle (2), and a dust discharge cover (10).    USE - The straw gasification furnace is useful for generating fuel gas.    ADVANTAGE - The furnace sufficiently uses each kind of agricultural regeneration resource such as straw to change into the gas of high fuel value, where the gas does not contain water and tar; it is clean, energy-saving, environment-friendly, and fit for use in countryside.    DETAILED DESCRIPTION - An energy-saving, environment-friendly straw gasification furnace comprises an internal cylinder (5), an external cylinder (7), a swaging bar (12), a charging mouth sealed cover (1), an O-type sealed ring (14), a swaging mechanism (6), a spring (13), a blowing device (11), an air inlet pipe (8), an exhaust opening (15), and a sealed cover tightening clip; where the internal cylinder (5) is in the external cylinder (7); a circular-ring hollow cavity is formed between the internal, external cavities; a filter sheet (17) is in the hollow cavity; an internal cylinder exhaust opening (4) is on the internal cylinder (5); an exhaust opening (15) is on the external cylinder (7); a swaging mechanism (6), an O-type sealed ring (14), and a charging mouth sealed cover (1) are installed on a swaging bar (12); a swaging handle (2) is on the top, a spring (13) is covered on the swaging bar between the swaging mechanism (6) and the charging mouth sealed cover, and the swaging mechanism (6) is installed in the internal cylinder (5); the charging mouth sealed cover (1) and the O-type sealed ring (14) are installed in the inclined groove; an air inlet pipe (8) is installed below the hearth, a blowing device (11) is installed on the air inlet pipe in the hearth; and a dust discharge cover (10) is on the lower part of the external cylinder (7).
