Title: Shut-down chimney used as a tower for a wind turbine
IPC: F03D11/04
Filed: 1997-04-10
Abstract: 1. Use of a shut-down concrete power station or industrial chimney (1) as a tower for a high-powered electric wind converter (2) with a rotor with an essentially horizontal axis (20) at the tip of which are fitted over-mounted rotor blades (9) which, after being shortened to an extent determinable on the basis of static and dynamic conditions and after the fitting of a holder on the wind converter, are rotated to the currently optimum wind direction eccentrically to and with a freedom to rotate about the vertical chimney axis. 2. Use of a shut-down concrete power station or industrial chimney (1) as a tower for a high-powered electric wind converter (2) with a rotor with an essentially horizontal axis (20) at the tip of which are fitted over-mounted rotor blades (9) which, after being shortened to an extent determinable on the basis of static and dynamic conditions and fitting a steel base (6, 7, 12, 16) for the wind converter on the chimney n such a way that the rotor blades can pass the chimney at a predetermined distance. 3. Use of Claim 2, wherein the steel base is mounted on the chimney having means to receive a wind converter. 4. Use of Claim 2 or 3, wherein said means (6 or 7) is reinforced concrete shaft with embedded bolt edge (5) including inner central passage. 5. Use of any preceding Claim wherein said means is uniformly distributed along the perimeter holes with cases for high-strength threaded bolts to fix combined carrying portion, including bolt edge (5). 6. Use of any preceding Claim wherein said means is a cylindrical or conic-shaped steel tower (6 or 7), the base of which is anchored on the top of the chimney (1). 7. Use of any Claims 4-6, wherein its length exceeds its diameter, is inserted into the shortened chimney (1) and fixed on said chimney (1) using one or a plurality of cantilevers catching horizontal loads of a support ring (12) and is provided with means to withstand vertical forces. 8. Use of Claim 1, wherein said fixing of the wind converter comprises load-carrying rings (14) with elements on which the wind converters, fixed to them, move concentrically around the tower and take the position towards the wind. 9. Use of Claims 1, 7 or 8, wherein said fixing means of the wind converter (2) is provided with a fixing ring (23), connected to the wind converter by a connecting rod (24) on the side opposite to the wind converter outside around the tower. 10. Use of Claims 1, 7-9, wherein said carrying structures such as load-carrying ring (14) and fixing ring (23), needed for mounting a plurality of wind converters, their size exceeds the outer diameter of the tower as much as to allow arrange within this space such auxiliary structures as a ladder (25), an elevator and different auxiliary hoists. 11. Use of Claim 1 or 7, wherein the load-carrying ring (14) is a supporting structure only to withstand an overturning moment. 12. Use of any preceding Claim wherein a plurality of wind converters (2) are arranged on the tower above each other and/or next to each other. 13. Use of any Claim 1, 7-12, wherein the wind converter (2) has an eccentric carrying structure (8) or an intermediate frame (13) between the rotation axis (19) of the wind converter (2) and a turning mechanism (10) with a guide and support ring (12) said mechanism concentrically sitting on the tower. 14. Use of a shut-down concrete power station or industrial chimney (1) in a shortened state as a tower for a high-powered electric wind converter (2) comprising one novel or all novel steps or a combination of features.
