DEMOLITION METHOD OF TURBINE FACILITY
PROBLEM TO BE SOLVED: To provide a demolition method of a turbine facility that is safe and has a short construction period using a heavy machine.SOLUTION: A demolition method of a turbine facility comprises: a preceding firing process in which an outer case of a generator is fused into a plurality of division pieces and legs of a turbine pedestal on which the generator and a turbine are installed are fused; a primary demolition process of a turbine building in which a heavy machine is arranged, side surfaces of the turbine building are removed, and the periphery of the generator, and the turbine is hollowed out; a removal process of the generator in which a rotor of the generator, division pieces of an upper part of the outer case, division pieces of a stator, and a lower part of the outer case are removed by the heavy machine; a removal process of the turbine in which an outer cover, an inner cover, a rotating blade portion and a pedestal of the turbine are grabbed and removed by the heavy machine; a removal process of the turbine pedestal in which the turbine pedestal is demolished and removed by the heavy machine; a removal process of a condenser in which the condenser is demolished and removed by the heavy machine; and a secondary demolition process of the turbine building in which the remaining building is demolished and removed by the heavy machine.SELECTED DRAWING: Figure 1
【課題】重機を使用した安全で工期の短いタービン施設の解体工法を提供する。【解決手段】発電機の外ケースが、複数の分割片に溶断されると共に、発電機とタービンが設置されるタービンぺデスタルの脚が溶断される先行火入れ工程と、重機が配置され、タービン建屋の側面が撤去され、発電機とタービンの周囲が、中抜きされるタービン建屋の第１次解体工程と、発電機のローターと、外ケース上部の分割片と、ステーターの分割片と、外ケース下部とを重機で撤去する発電機の撤去工程と、タービンの外カバー、内カバー、回転羽根部及び台座を重機で掴み撤去するタービンの撤去工程と、重機で解体し撤去するタービンぺデスタルの撤去工程と、重機で解体し撤去する復水器の撤去工程と、残りの建屋を重機で解体し撤去するタービン建屋の第２次解体工程と、が備えられる。【選択図】図１
