Abstract (en)
[origin: US6880338B2] The invention relates to a lead-in structure for coupling of a turbo generator in a circulating process of a circulating medium. The turbo generator includes a turbine and a generator as well as possibly also a feed pump enclosed in a common casing structure. The casing structure also includes at least a first duct for hot, steam-like circulating medium entering the turbine, a second duct for circulating medium exiting the turbine, and a third duct for cooled liquid circulating medium, which, for example, enters the feed pump. The third duct includes an annular channel that is placed, preferably concentrically, around the second duct, which includes an annular channel. The first duct includes an annular channel that is placed, preferably concentrically, between the second duct and the annular channel of the third duct. The fixing flange applying the lead-in structure may include a closing valve that is controlled with a pressurized medium and that is arranged to keep the tubular channel of the second duct normally open and to keep it closed for releasing the casing element, wherein the closing valve is placed inside the tubular channel.
