Multiple centripetal vents are provided with vertical blower；First circular support pipe and the second circular support Guan Jun by connecting pipe with
Fan outlet is connected；Fuel-feed pipe, fuel-feed pipe discharging opening and combustion chamber, fuel-feed are provided with housing side
Pipe charging aperture is connected with auger discharging mouthful, auger charging aperture connection fuel-feed bucket.
Further, fuel-feed pipe is connected by connecting pipe with fan outlet, accelerates the whereabouts of fuel, makes fuel
Will not be blocked in fuel-feed pipe.
Further, two ends connect many drainpipes of reservoir chamber, many interlaced installations of drainpipe on combustion chamber top
In a combustion chamber, heat exchange is more thorough, improves the utilization rate of heat energy.
Further, multiple scale removal rods through housing, reservoir chamber and combustion chamber are provided with reservoir chamber bottom position, are removed
Incrustation scale rod is detachably connected on housing, the setting of scale removal rod, improves heat exchanger effectiveness.
Further, lower housing portion is provided with watch window near fire grate position, and housing bottom is provided with ash hole.
The beneficial effects of the invention are as follows：Simple structure, modern design, by changing fire grate structure and combustion air air feed shape
Formula, fire grate is provided to make to be formed in combustion chamber and blow combustion air on bottom；Opened on second circular support pipe and vertical blower
There are multiple centripetal vents, middle and upper part in combustion chamber can be made to form centripetal combustion air, combustion air is blown on bottom makes biomass fuel
Material particle suspends in a combustion chamber, obtains sufficient oxygen, and blowing combustion air on the centripetal combustion air of middle and upper part and bottom being capable of shape
Into convection current wind, and biomass fuel pellet is preferably disperseed, so that fuel combustion is more abundant, improve efficiency of combustion.
