Chimney draught optimizer contains the reduction part (2), which is on its lower side adapted to the installation on the current chimney insert and on its upper side adapted to the placing of the diffusion member (1), or contains the reduction part (2) which is on its lower side adapted to the installation on the current chimney insert and which is an integral part of the diffusion member (1), wherein the sleeve (3) is placed on the diffusion member (1) from outside and the cover (4) with the splitting cone (5) is settled on the sleeve (3). Such chimney draught optimizer has underneath end of the splitting cone (5) in the same height or higher than the upper edge of diffusion member (1), wherein the maximum distance between underneath end of the splitting cone (5) and the upper edge of diffusion member (1) is 1/2 of internal diameter of the narrowest part of diffusion member (1), wherein the internal diameter of diffusion member (1) decreases from below upstairs no more than 1:2. The diffusion member (1) is furnished on its upper edge by the ending (6) with the inside inclined area (7), and there is a system of lower openings (8) located in lower part of the sleeve (3) and interconnected through the space (10) situated between diffusion member (1) and sleeve (3) with the system of upper openings (9) located in upper part of sleeve (3). |
