Gyroidal stream-guiding webs are inlaid on the inside wall of chimney. The optimal slope of chimney is designed and the chinmey neck for air inlet is connected with the bottom of chimney in the direction of tangent and at a determined angle of elevation. With this invention, the diffusion condition of smoking cloud can be improved, the heigh of chimney can be reduced, the service life can be prolonged, and the displacement of dust and the density of harmful gases down to ground can be decreased.
