<p>Disclosed is a rotatable chimney stack which comprises: a main body inside which smoke is generated; a stack part connected to the main body, having an inlet into which the smoke generated in the main body flows, and having an outlet which discharges the smoke generated in the main body to the outside and obliquely intersects with a vertical axis penetrating the inlet; and a rotating part interposed between the main body and the stack part and rotating the stack part in order to position the stack part in the direction of a draught along the draught. According to the present invention, the discharge direction of the smoke discharged from the chimney stack is always parallel to the direction of the draught depending on automatically changing the discharge direction of the smoke discharged from the chimney stack along the direction of wind outside the chimney stack so that the diffusible property of the discharged smoke is improved.</p> |
