Greatly, and then waste of fuel can be reduced with flexible modulation I and II air distribution size；When needing deashing, coke cleaning, drawing and pulling type is kept off
Plate pulls open, and dust, burnt object is made to fall into ash device.
Broken burnt pawl, two fire bars gaps of the grate that the blade tooth of the broken burnt pawl is placed in are equipped in drawing and pulling type baffle top surface
Between, when pulling drawing and pulling type baffle, broken burnt pawl thereon follows movement, can be cleaner by dust, blocky burnt object cleaning,
It is minimum from the windage entered with aerofoil air inlet, further decrease air loss.
Present invention is mainly used for the existing technological transformations for burning coal coaster for baking tobacco, and structure is simple, and manufacturing cost is low, firstly, its
Three-level air distribution may be implemented, the bottom, periphery and center of entire combustion zone is made to be in oxygen abundance state, burning sufficiently,
Uniformly, stove reliability of operation and safety be ensure that；Secondly, making burner chamber body be in sealing by drawing and pulling type baffle
State is aerated oxygen supply, effectively prevent air loss, so that oxygen supply is sufficient, burning is abundant, effectively prevents burning coking existing
As；In addition, according to actual needs, by adjusting drawing and pulling type baffle openings size, flexible modulation air distribution size guarantees fuel
Minimum, to substantially increase heat utilization rate drop, reduce harmful exhaust discharge amount is consumed, energy conservation and environmental protection is practical, has
Good economic and practical and promotion prospect.
