Definitions

  • the invention is directed to a power plant comprising a steam generator with connected water / steam circuit and turbine or turbine set integrated therein, the steam generator having a fossil fuel and / or biomass combustible combustion chamber and wherein the water / steam circuit steam side with a thermally coupled to a heat storage heat exchanger conductively connected and / or thermally coupled, wherein the water / steam circuit is connected in line with the heat exchanger such that thermal energy of the steam from the water / steam cycle is thermally coupled into the heat exchanger.
  • the invention is directed to a method for storing generated in a power plant with a steam generator with connected water / steam cycle and integrated turbine or turbo set heat, the steam generator has a fossil fuel and / or biomass combustible combustion chamber and wherein the water / steam cycle on the steam side with a thermally coupled to a heat storage heat exchanger connected in series and / or thermally coupled, wherein in the heat exchanger heat energy from the steam of the water / steam cycle is coupled and coupled into the heat exchanger.
  • the electric power feeding power generation and the electric power taken from the power grid must be balanced. Due to the expansion of renewable energies, there are at times strong overcapacities, but in some cases also undercapacities in the grid.
  • the fluctuating supply of renewable energy and thus the fluctuating feed-in of renewable energies into the power grid must balanced by conventional power plants. This makes it necessary to equip conventional power plants with a quickly controllable power plant capacity, so that they can shut down quickly in case of overcapacity and quickly booted up under sub-capacity, depending on the requirements of the grid.
  • Fossil-fired power plants are now however provided with the disadvantage that they can not be arbitrarily turned on and off and are mobile up and down in relation to their output power.
  • the power of steam power plants especially the coal-fired steam generator, can not be changed arbitrarily strong and fast.
  • minimum operating and minimum downtimes must be observed to avoid excessive system wear. If power plants are to remain on the grid as a so-called "hot reserve" for a direct restart for power generation, then they must be in permanent operation with their own Minimum or minimum load ready.
  • a generic power plant and a generic method with an arrangement for storing energy are from the US 4,164,848 A known.
  • This document discloses a power plant with a coupled in a water / steam cycle heat storage, which in turn is in heat communication with heat exchangers, decouple the heat energy in the water / steam cycle.
  • a coupling of thermal energy of the steam in the heat storage takes place such that from the feed water line of the water / steam cycle preheated water, which is branched off upstream of a steam generator from the water / steam cycle, the heat accumulator is supplied.
  • steam is supplied to the heat storage downstream of the steam generator from the water / steam cycle. In this respect, the heat energy of the steam is coupled into the heat storage.
  • Decoupling occurs in that the water stored in the heat storage is supplied to the heat exchangers and heat energy is released in the heat exchangers to form steam to the water / steam cycle. After passing through the heat exchanger, the water is fed to the feedwater line upstream of the steam generator.
  • the DE 10 2009 060 089 A1 discloses a solar thermal power plant in which a heat storage is integrated into the water / steam cycle. An interaction of this heat storage with an associated heat exchanger is not apparent from this document.
  • the invention has for its object to provide a solution that makes it possible to adapt a power plant to the fluctuating feed demand of the connected power grid and to flexibilize with respect to its Stromeinspeisebaum.
  • this object is achieved in that thermal energy of the steam is transmitted in the heat exchanger to a heat transfer medium and coupled to the heat transfer medium heat energy in the heat storage.

  • heat energy from the steam is indirectly decoupled from the water / steam cycle into a heat store via a heat exchanger and, if appropriate, directly directly into a heat store, wherein both outcoupling paths can possibly also be operated in parallel.
  • This makes it possible to flexibilize power plants insofar as generated steam does not necessarily have to be routed to generate electricity through the turbine set or turbo set, but is passed through at least one heat exchanger and optionally at least one heat storage where the steam (its) gives off energy.
  • the amount of steam used for power generation can thereby be reduced, and thus the amount of electricity or electrical energy fed into the network by the power plant can be regulated so that part of the steam quantity is "stored".
  • the stored energy when the power plant is restarted, the stored energy may be used to achieve a higher rate of power change in percent / minute than the usual 3-5% / minute by the energy stored in the form of thermal energy when starting in the form of steam, for example, to the low-pressure preheaters of the water / steam cycle of the power plant is provided.
  • peak / midload current in addition to the (main) water may be provided by means of a salt / water steam heat exchanger, preferably a once-through steam generator, and any additional turbine circuit / Steam cycle of the power plant are provided and fed into the grid.
  • the invention is thus characterized in design of the power plant by the fact that the water / steam circuit on the steam side connected to the heat storage line connected and / or thermally coupled, the water / steam cycle is so connected to the heat storage line connected, that heat energy of the steam the water / steam cycle is thermally coupled out in the heat storage.
  • the method is characterized by the fact that the Water / steam cycle on the steam side connected to the heat storage line connected and / or thermally coupled, being coupled in the heat storage heat energy from the steam of the water / steam cycle and coupled into the heat storage.
  • heat energy of the steam is transferred in the heat storage to a heat transfer medium and / or a heat storage medium.
  • the invention In order to be able to transfer current overcapacities present in the network from the grid to a storage, the invention also provides that the heat storage is electrically heated, or that the heat storage in the power grid existing overcapacity of electricity and / or operation of the power plant in his Minimum or minimum load range generated, not to be fed into the grid excess current via a with the respective current and / or excess current electrically heated and arranged in the heat storage heater thermal energy is supplied and stored in the heat storage. This makes it possible to store energy, if due to the fluctuating feed-in of renewable energies such as wind or photovoltaic in the grid is too high a feed.
  • the power plant can be restarted relatively quickly, but alternatively, also parallel to the (main) water / steam cycle of the power plant a second water / steam cycle with associated turbine set or turbo set can be operated, which then immediately without the power plant must be started, generates electricity and fed into the network.
  • the invention therefore provides in an embodiment that the heat storage of the power plant in stored heat auskoppelbarer manner is connected to at least one further steam generator, which forms a preheater, superheater or reheater in the or a second water / steam cycle.
  • the invention provides in an embodiment that the heat storage of the power plant in stored heat auskoppelbarer manner is connected to the or a second heat exchanger.

  • This can then in development of the method also be provided that when restarting the power plant from its minimum or minimum load range stored in the heat storage heat in the and / or in the second water / steam cycle, preferably in the range of Niederdruckvor lockerrn coupled.
  • the heat storage can be designed as a steam storage or Ruths storage, salt storage, concrete storage or hot water storage.
  • a particularly suitable heat storage medium is molten salt, in particular a mixture of KNO 3 and NaNO 3 .

Since electric heating has an efficiency of nearly 100% and conventional steam power processes in the temperature range 530 ° C have cycle efficiencies of 38-42%, the efficiency of the energy storage is higher than many other alternatives.
  • the inventive measure in power plants to integrate a heat exchanger and an associated heat storage in the steam generation of the power plant or possibly equipped with its own associated steam generation including a turbine or turbo set with attached generator can in the replanning of power plants, especially in a new construction of fossil-fired power plants , planned and provided as additional equipment or additional equipment.
