Regenerative agent efferent duct is symmetrically installed on the two side of regenerative agent concetrated pipe.
Preferably, valve is installed on the regenerative agent efferent duct.
Preferably, being uniformly provided with several air holes on the cellular-type aerofoil, several air holes are to tilt upward, and
Angle is 30 °.
Compared with prior art, the beneficial effects of the utility model are：It is easy to implement and rapidly and uniformly burns so that containing charcoal
Rate is consistent, easy to use, easy to operate, efficient.
Description of the drawings：
For ease of explanation, the utility model is described in detail by following specific implementations and attached drawing.
