Abstract
La turbine à vapeur (1), comporte un corps haute pression (2) et un corps basse pression (3), un réducteur de vitesses (4) et un alternateur (5). La turbine est caractérisée en ce que le corps haute pression (2) comporte un seul étage d'ailettes (20). Cet étage assure la même fonction que le corps haute pression multi-étages avec une conception d'ailettes différente de celle des turbines multi-étagées. De plus, le corps haute pression (2) comporte aussi une tuyère monobloc. The steam turbine (1) comprises a high pressure body (2) and a low pressure body (3), a speed reducer (4) and an alternator (5). The turbine is characterized in that the high pressure body (2) comprises a single stage of fins (20). This stage performs the same function as the multi-stage high pressure body with a fin design different from that of multi-stage turbines. In addition, the high pressure body (2) also includes a one-piece nozzle.
