摘要： The invention relates to a method and device for cooling at least one low-pressure stage (4) of a steam turbine (1) comprising a steam admission area (2) and a steam exhaust area (3). The steam turbine (1) is connected to at least one condenser (5) or is configured as a back pressure turbine. Condensate and/or steam from a cooling system (6) is injected as a cooling medium into the low-pressure stage (4) via a dosing device (7). Said condensate and/or steam is injected according to a temperature value which is measured in the low-pressure stage (4) and according to a parameter which is directly or indirectly correlated to the mass flow rate through the low-pressure stage (4). In an advantageous manner, such a method for cooling a low-pressure stage (4) of a steam turbine (1) reduces the exposure of the steam turbine (1) blades to the risk of erosion resulting from the beating of drops and is easier to control than control systems which are only dependent on temperature.

摘要： The invention concerns a method of cooling the low-pressure stage of a steam turbine (1) connected into a water/steam loop (12). Coolant (K') flow through parts (24) of the low-pressure stage (2), particularly when idling. In order to ensure particularly effective cooling and to be able also to make use of the heat thus obtained, the condensate (K) from a condensor (4) connected downstream from the steam turbine (1) is used as the coolant (K'), the condensate giving up the heat absorbed during the cooling process to the water/steam loop (12). To this end, the low-pressure stage is connected to a coolant line (22, 22') which is connected to the outlet end of the condensor (4) and which includes a heat exchanger (16, 16') connected into the water/steam loop (12).

摘要： The invention relates to a process for cooling a low-pressure steam turbine (1) in ventilation mode. The low-pressure steam turbine (1) has a closable inlet (2) through which steam can be admitted in the power mode and blocked in the ventilation mode, an outlet (3) communicating with a condenser (5) for condensing the steam into a condensate and a tapping (4) between the inlet (2) and the outlet (3). A tap line (6) is connected to the tapping (4) to evacuate steam and/or condensate in power mode. According to the invention, steam is supplied via a steam by-pass (12) to the tap line (6) to cool the low-pressure steam turbine (1) in ventilation mode. Condensate is also preferably supplied to the tap line (6). According to the invention, the cooling effect in the low-pressure steam turbine (1) is largely restricted to the heavily loaded components in ventilation mode and the cooling media are taken from resources which in any case, are available.

摘要： A cooling fluid flow control system 100 for a turbine section of a steam turbine system 10 and a related program product are provided. In one embodiment, a system includes at least one computing device 204 operably connected to a cooling system. The computing device may be configured to control a flow rate of cooling fluid supplied to a steam turbine system by the cooling system by performing actions including modeling a sensitivity of a wheel space temperature to a change in the flow rate in the form of a piecewise linear relationship, the piecewise linear relationship including a flooded flow rate above which the wheel space temperature becomes insensitive to increased flow rate. The computing device also periodically modifies the flow rate of the cooling fluid supplied to the wheel space of the turbine section to approximate a minimum flooded flow rate based on the measured flow rate and the modeling.

摘要： The invention relates to a method for controlling a cooling process of turbine components (8, 10, 12) of a steam turbine shaft, wherein an air flow mixed with a water mist is used to cool the turbine components (8, 10, 12) during a mist cooling phase (P4). In particular, the mist cooling phase (P4) is preceded by an air cooling phase (P3), during which an air flow is used to cool the turbine components. A constant temporal temperature gradient is specified for the cooling process, wherein the air flow density is adjusted by means of the valve position of a controllable regulating valve (26) and a switch is made from the air cooling phase (P3) to the mist cooling phase (P4) if the maximum air flow density is reached and in particular if the regulating valve (26) is fully open.
