<p>The fan wheel (11.2) for gases has a bladed impeller driven by a motor to produce a gas volume flow during rotation of the impeller around its rotational axis. At least one element (42) consisting of several reciprocally movable links (60) is located in the volume flow generated by the impeller. This element is rotationally driven around the rotational axis of the impeller. The impeller and element are rotationally driven by the same motor. Independent claims are included for an element consisting of several links joined together with reciprocal movability like chain sections, and for a device for the burning of bio and/or solid matter masses equipped with a fan unit incorporating the aforesaid fan wheel.</p> |
