Definitions

  • the invention relates to a steam turbine plant and a method for operating the steam turbine plant.
  • a steam turbine plant is used in particular in a thermal power plant for the production of electrical energy.
  • the steam turbine plant to a steam turbine and a steam generator, heated with the feed water and thereby live steam is generated, which is provided to the steam turbine for driving the same.
  • 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 object of the invention is to provide a steam turbine plant and a method for operating the steam turbine plant, wherein the steam turbine plant has a high thermal efficiency over a wide power range.
  • the steam turbine plant according to the invention has a steam turbine, a steam generator and a process steam-operated feedwater preheating device, the steam turbine having a Matterlastbypasstechnisch with the overload operation of the steam turbine live steam between the steam turbine inlet and the removal point of Why Suitewasservor becamermungs Surprise can be fed, wherein the feedwater pre-heating device has an additional extraction line to the Overload bypass line is connected so that during partial load operation of the steam turbine can be removed from this process steam and the feedwater preheating device for additional feedwater pre-heating is zuglagbar.
  • 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 additional extraction line is connected to the overload bypass line, the point of the steam turbine at which both the overload bypass line and the additional extraction line open into the steam turbine, 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 extraction line easy and is constructed inexpensively.
  • the overload bypass line and the additional tapping line is advantageous equalization of the efficiency curve as a function of the power of the steam turbine achieved.
  • 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 in the operating state of the steam turbine below the rated power, 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 increase of the feedwater temperature at the feed water inlet of the steam generator while increasing the amount of feed water at the feed water inlet of the steam generator, 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 feed water preheating device preferably has a feedwater preheater, which is operated by the process steam taken from the sampling point and by the process steam taken with the additional sampling line. This will both operate to operate the feedwater pre-heater supplied to the extracted by the additional extraction line process steam as well as the withdrawn from the sampling process vapor.
  • 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 be advantageously used with regard to the optimization of 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. This is particularly advantageous because the pressure level of the process steam, with which the additional preheater is operated, is higher than the pressure level of the process steam, with which the feedwater pre-heater is operated.
  • the feedwater preheating means comprises a three-way valve, with which the additional preheater in the feedwater flow can be switched on and switched off from the feedwater flow.
  • a partial flow of the feedwater flow through the additional preheater can be conducted with the three-way valve.
  • an additional extraction valve is preferably installed, with which the mass flow of the process steam in the additional extraction line is controllable.
  • the steam turbine is a high-pressure steam turbine.
  • a steam turbine installation 1 has a steam generator 2, which is provided for generating live steam in the steam turbine installation 1.
  • the steam turbine plant 1 further has a feedwater supply line 3, with the feed water is supplied to the steam generator 2.
  • a superheater 4 is provided, through which the live steam is provided in a supercritical state.
  • the steam turbine plant 1 to a steam turbine 5, which is designed as a high-pressure stage 6 and at the entrance of the live steam via a steam line 7 for driving the steam turbine 5 can be flowed.
  • the mass flow of the live steam can be controlled with a built-in steam line 7 main steam valve 8.
  • 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 removal line 10, which leads to a feedwater pre-heater 11. 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 Feedwater pre-heater 11 is designed as a heat exchanger which is connected in the feedwater supply line 3, so that a preheating of the feedwater can be accomplished by condensing the process steam in the feedwater pre-heater 11.
  • the condensate produced during condensation of the process steam can be discharged via a condensate line 12 in a condensate collecting line 13.
  • 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 overload bypass line 14 Downstream of the overload bypass valve 16, the overload bypass line 14 opens into an additional extraction line 17, which leads to an additional preheater 19.
  • an additional extraction valve 18 is installed, with which the process steam flowing through the additional extraction line 17 can be controlled in its mass flow and with which the additional extraction line 17 can be isolated.
  • the additional preheater 19 is designed as a heat exchanger, which can be flowed through both from the process steam from the additional extraction line 17 and from the feed water from the feedwater supply line 3.
  • 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 is flowed through the additional preheater 19, is adjustable.
  • 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.
  • the steam turbine 5 Over the power range of the steam turbine 5, its thermal efficiency is variable according to their design and construction.
  • the steam turbine 5 is designed so that it should have the maximum thermal efficiency at a given rated power. If the steam turbine is operated above the rated power, the overload bypass valve 16 is opened and the additional intake valve 18 is closed, whereby the overload bypass line 14 is released and the additional extraction line 17 is insulated. As a result, live steam is fed between the steam turbine inlet of the steam turbine 5 and the removal point 9. Once the steam turbine 5 is operated below the rated power, the overload bypass valve 16 is closed, so that the overload bypass line 14 is isolated, and the additional bleed valve 18 is opened, so that the additional extraction line 17 is released.
  • process steam is withdrawn from the steam turbine 5 upstream of the withdrawal nozzle 9, which is fed to the additional preheater 19.
  • the mass flow of the process steam in the additional extraction line 17 is controllable.
  • the process steam flows from the additional extraction line 17 into the additional preheater 19 and is condensed with the release of heat.
  • the resulting condensate is fed to the condensate line 12 of the condensate collecting line 13.
  • the three-way valve 20th Depending on the pressure level of the process steam at the inlet of the additional preheater 19 and the resulting preheating for the feed water at the outlet of the additional preheater 19 in the feedwater preheat pipe 21 and the consequent mixing of the feedwater in the downstream portion of the feedwater supply pipe 3 is the three-way valve 20th to operate accordingly.
