Abstract:
1. A system for using mechanical work done by flue gases with high temperatures and high particulate matter to generate electricity, said system comprising: a. a ring induction generator including a first ring comprising a stator with a plurality of alternating slots and teeth integrally formed only along an inner peripheral surface of said first ring, a second ring comprising a rotor positioned concentrically within said first ring separated from said inner peripheral surface by a gap sized to provide space within said gap for a protective material on said first and second rings and to reduce damage from particulate matter, and a plurality of toroidally wound coils provided in each of said plurality of slots, said coils being wound to form an outside wound stator; b. a turbine rotatably mounted on a central shaft positioned concentrically within said second ring, wherein said turbine includes turbine blades with tips extending radially outwardly from said central shaft to fixedly connect with an inner surface of said second ring, whereby rotation of said turbine produced by flue gases causes said second ring to rotate with said turbine, directly driving the rotor; and c. support means comprising a plurality of radially spaced struts connected directly between a hub concentrically mounted with said central shaft and an outer circumference of said first ring.
