Abstract (en)

[origin: WO0223014A1] 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 (1) comprises a turbine (11) and a generator (13) as well as possibly also a feed pump (12) enclosed in a common casing structure (20, 30), which casing structure (20, 30) also comprises at least a first duct (21) for hot, steam-like circulating medium (8) entering the turbine (11), a second duct (25) for circulating medium (9) exiting the turbine (11), and a third duct (24) for cooled liquid circulating medium (10a), which for example enters the feed pump (12). The third duct (24) comprises an annular channel (23) which is placed, preferably concentrically, around the second duct (25), which comprises an annular channel (26), and the first duct (21) comprises an annular channel (22) which is placed, preferably concentrically, between the second duct (25) and the annular channel (23) of the third duct (24). The fixing flange (20) applying the lead-in structure may comprise a closing valve (28) which is controlled with a pressurized medium and which is arranged to keep the tubular channel (26) of the second duct (25) normally open and to keep it closed for releasing the casing element (30), wherein the closing valve (28) is placed inside the tubular channel (26).
