  • This cycle of the steam turbine plant is conventionally designed so that it has the maximum thermal efficiency at full load of the steam turbine. Other operating conditions, which are below the full load, lead to a correspondingly lower thermal efficiencies.
  • the partial load operation of the steam turbine plant in particular if it is used in the power plant, of high relevance, since for example in the steam turbine plant a power reserve is to be maintained for coping with overload operating conditions.

  • the steam turbine plant according to the invention has a control system for carrying out the method according to the invention described below.
  • the method according to the invention for operating the steam turbine plant has the steps of: determining the optimum efficiency and the associated rated power of the steam turbine; as soon as the steam turbine is operated above the rated power, releasing the overload bypass line and isolating the auxiliary tapping line so that live steam is fed between the steam turbine entrance of the steam turbine and the tapping point of the feedwater pre-heater; as soon as the steam turbine is driven below the nominal line, isolating the overload bypass line and releasing the additional tapping line, so that process steam is taken between the steam turbine inlet of the steam turbine and the extraction point and fed to the feedwater pre-heater for additional feedwater pre-heating.
  • the overload bypass line for the operation of the steam turbine at overload and the additional extraction line for the operation of the steam turbine is provided at partial load.
  • a partial mass flow of the live steam is guided around a first part of the high pressure blading of the steam turbine and fed into the steam turbine.
  • the power surplus which is above the rated power, can be generated by the steam turbine without the live steam pressure at the steam turbine inlet being increased compared with the nominal load operating state.
  • the operation of the additional tapping line in part-load operation of the steam turbine removes process steam from the steam turbine which is fed to the feedwater pre-heater for additional feedwater pre-heating in the part-load operation of the steam turbine, thereby raising the feedwater temperature.
  • the thermodynamically induced lowering of the feedwater temperature can be counteracted with decreasing steam turbine power.
  • the fact that a lowering of the thermal efficiency of the steam turbine plant would be accompanied by the feed water temperature reduction, is achieved with the operation of the additional extraction line in partial load operation of the steam turbine that the thermal efficiency of the steam turbine is high.
  • the thermal efficiency is high, so that over a wide power range of the steam turbine whose thermal efficiency is high.
  • the point of the steam turbine at which both the overload bypass line and the additional extraction line open into the steam turbine provided the same point for feeding the live steam in case of overload as well as for the removal of the process steam in the partial load case .
  • the steam turbine only a single point at which both the overload bypass line and the additional extraction line are attached.
  • the provision of two or more points for feeding the live steam in case of overload and removing the process steam in part load would be structurally complex and only correspondingly costly to implement, so that the steam turbine plant according to the invention with its single junction for the overload bypass line and the additional tapping line easy and is constructed inexpensively.
  • the overload bypass line and the additional extraction line it is advantageous to achieve a homogenization of the efficiency curve as a function of the power of the steam turbine.
  • load changes of the steam turbine plant are mobile at a constant and high level of thermal efficiency faster.
  • the load range is large, in which the steam turbine plant is operable at a constant over the time and produced by the steam generator steam temperature.
  • the steam turbine plant has a minimum operating point at low partial load level at which the steam turbine is still operable at stable conditions in the steam turbine plant (Benson minimum load).
  • the additional feedwater is such that the feedwater temperature at the feed water inlet of the steam generator via the load is constant.
  • the additional feedwater pre-heating such that the feedwater temperature at the feed water inlet of the steam generator increases with decreasing power of the steam turbine plant.
  • the minimum operating point of the steam turbine plant is displaced towards lower part loads.
  • the increase in the feedwater temperature can advantageously be exploited to the limit of the thermal and mechanical load capacity of the steam generator.
  • Any of the steam turbine downstream flue gas process steps, such as a DeNOx system can be operated due to the raised feedwater temperature at a higher flue gas temperature.
  • This feedwater pre-heater preferably has a feedwater pre-heater that is different from that of the Extraction point removed process steam and operated by the extracted with the additional extraction line process steam. As a result, both the process steam withdrawn through the additional extraction line and the process steam removed from the removal point are supplied for operating the feedwater pre-heater.
  • the feedwater preheating device has a feedwater preheater operated by the process steam withdrawn from the sampling point and an auxiliary preheater operated by the process steam withdrawn with the supplemental sampling line. Due to the fact that the additional preheater is provided in the steam turbine plant, the integration of the additional preheater into the cycle of the steam turbine plant can be performed independently of the integration of the feedwater preheater, so that degrees of freedom can advantageously be utilized with regard to optimizing the thermal efficiency of the steam turbine plant. In this case, it is preferable for the additional preheater to be connected in the feedwater flow downstream of the feedwater preheater. Thus, the additional preheater is advantageously downstream of the feedwater pre-heater.

  • the live steam can be relaxed as process steam, whereby the shaft power of the steam turbine 5 can be obtained.
  • the steam turbine 5 has a removal nozzle 9, which opens into a withdrawal line 10 leading to a feedwater pre-heater 11 leads. Through the removal nozzle 9 process steam can be tapped off from the steam turbine 5, which is guided via the extraction line 10 to the feedwater pre-heater 11.

  • the steam turbine 5 has an overload bypass line 14, which branches off from the main steam line 7 upstream of the main steam valve 8 and leads to an overload bypass pipe 15 of the steam turbine 5, which is arranged between the main steam inlet and the outlet nozzle 9.
  • an overload bypass valve 16 is provided with which both the live steam mass flow flowing through the overload bypass line 14 and the overload bypass line 14 can be isolated.

  • the additional preheater 19 is arranged downstream of the feedwater preheater 11, so that feed water which has already been preheated by the feedwater preheater 11 can be flowed through the additional preheater 19.
  • the additional preheater 19 is connected in parallel to the feedwater supply line 3 via a feedwater preheating line 21.
  • a three-way valve 20 is installed, with which the feedwater flow in the feedwater supply line 3, which can be flowed through the additional preheater 19, is controllable.
  • the three-way valve 20 is to be switched accordingly when either no feed water, the entire feedwater flow or only a part thereof is to be passed through the additional preheater 19.
