The first air duct is located in the combustion chamber and is provided with a number of first gasification holes to introduce secondary air into the center of the combustion chamber.

2. The biomass gasifier according to claim 1, wherein The first air duct has a rectangular cross-section and is inclined toward one side facing the middle of the combustion chamber, and the first vaporization hole is located on this side.

3. The civilian biomass gasification furnace according to claim 1 or 2, characterized in that: A second air duct is also connected between the pair of jackets, and the cross-section of the second air duct has a trapezoidal structure on the front side and a rectangular structure on the rear side. The trapezoidal inclined surface of the second air duct is provided with several second vaporization holes that discharge air toward the outer wall of the first air duct, and the bottom of the second air duct is provided with a secondary air inlet that communicates with the outside. The rectangular outer side plate of the second air duct extends upward to separate the combustion chamber and the dust removal chamber, and a rectangular through hole is provided on the outer side plate to connect the combustion chamber and the dust removal chamber.

4. The civilian biomass gasification furnace according to claim 3, characterized in that: The rectangular top of the second air duct is provided with several third vaporization holes; The outlet direction of the third vaporization hole is perpendicular to the axial direction of the rectangular through hole; One long side of the rectangular through hole is flush with the top of the rectangle of the second air duct.

5. The civilian biomass gasification furnace according to claim 4, characterized in that: The first vaporization hole, the second vaporization hole, and the third vaporization hole have the same diameter; The first vaporization holes are arranged in two rows in a straight line, and the second and third vaporization holes are each arranged in one row in a straight line.

6. The civilian biomass gasification furnace according to claim 4 or 5, characterized in that: The furnace body at the top of the combustion chamber has a main stove opening that is directly opposite the center of the combustion chamber and located in front of the first air duct. The first pot ring assembly is movably embedded in the main stove opening. The furnace body at the top of the dust removal chamber is provided with a pair of auxiliary stove openings, and a second pot ring assembly is movably embedded in each of the auxiliary stove openings; The first pot ring assembly and the second pot ring assembly each include multiple pot ring bodies of different diameters that are nested and stacked together, and the smallest pot ring body is movably covered with a dust cover.

7. The biomass gasifier according to claim 6, wherein The countertop where the secondary stove is located is higher than the countertop where the main stove is located.

8. The civilian biomass gasification furnace according to claim 7, characterized in that: The dust removal chamber is equipped with a fire baffle plate with a pair of dust collection holes at the top; One end of the fire baffle plate is inclined downward and extends to the vicinity of the rectangular through hole to separate it from the outer side plate, thus forming a dust collection channel. The ash collection holes correspond one-to-one with the auxiliary stove openings.

9. The civilian biomass gasification furnace according to claim 1 or 8, characterized in that: The feeding port is located on the upper front side of the furnace body, and a feeding cover is connected to it via a hinge; The ash collection chamber is equipped with an ash extractor that can be pulled out from the front end of the furnace body to collect the ash and slag produced in the combustion chamber. The front panel of the ash extractor is equipped with an adjustable damper for adjusting the primary air volume entering the combustion chamber. The exhaust port is located on the upper rear side of the furnace body and is connected to a smoke pack with a smoke pipe; The furnace body below the flue gas outlet is provided with an ash cleaning port, and the ash cleaning port is movably connected to a baffle.
