  • MOTOR-DRIVEN CHIMNEY DRAFT SYSTEM AND AN IMPELLER FOR USE IN THE SYSTEM
    Publication number: 20130130605
    Abstract: Impeller for a motor-driven chimney draft system, comprising a flue gas impeller (10) for creating, in a flue gas passage, a draft in a flue gas downstream direction. A flue gas deflector disk (20) is situated downstream relative to the flue gas impeller (10) and connected to the flue gas impeller (10); and a hub for connecting the impeller to an end portion of a driving shaft of a motor (100), wherein the hub and the end portion of the driving shaft, when connected, are both situated downstream relative to the flue gas deflector disk (20), the hub indirectly connected to the flue gas deflector disk (20) by means of intermediate members. Advantageously the intermediate members are impeller blades (40) connected to the downstream side of the flue gas deflector disk (20) and to a venting disk (30) with venting holes (31, 32) so as to form a turbine.
