  • EP-A2-1 055 801 describes a method for operating a Steam power plant known in which by means of partial steam mass flows from the amount of turbine steam as feed water Condensate used preheated to near the boiling temperature becomes. To avoid the decrease in the power consumption at the subsequent steam turbine stages provide that the waste heat from fuel cells to preheat the condensate is used. By preheating the feed water from the waste heat of the fuel cells and the associated Increase in the amount participating in the expansion achieved an increase in steam process efficiency. Through the integrated in the preheating section of EP-A2-1 055 801 Fuel cell arrangement is a constructive and cost-effective relatively expensive preheating due to the external heat supply achieved through the fuel cells.

Another job the invention is to provide a steam power plant with such an operating method can be carried out.
  • This object is achieved by a method for Operation of a steam power plant solved, being in a boiler generated steam after flowing through at least one turbine is condensed in a condenser, the obtained Preheated condensate and the boiler as boiler feed water is fed back, the condensate for preheating the condensate into a first partial flow and a second partial flow divided, only the first partial flow preheated, and the second partial stream mixed again with the preheated first partial stream becomes.
  • the invention is based on the consideration that for Performance increase of a switched in a steam power plant Turbine the steam mass flow through the turbine on the one hand and on the other hand, the preheating temperature of the boiler Boiler feed water must be taken into account. Both process variables are linked together by the usually in Steam power plants tapping the turbine, wherein a partial steam mass flow for preheating the condensate obtained is taken from the steam turbine process. This steam extraction goes at the expense of the performance of the turbine, in particular on the overall efficiency of the steam power plant. That in Condenser obtained condensate is used in the known plants fully preheated using bleed steam, while doing so on a preheated the highest possible temperature near the boiling temperature, before it is fed into the boiler as boiler feed water becomes.

This is particularly evident more efficient heat consumption than with a total conversion the preheating section, at least at times at all no condensate is preheated, i.e. the first partial flow Is 0. This is for example for high pressure preheaters or the like of importance.
  • the first Partial flow preheated with bleed steam from the turbine By preheating only the first partial stream with bleed steam from the turbine it is ensured that only one is opposite correspondingly lower than conventional tapping Amount of bleed steam required for preheating. Consequently more process steam is immediately available in the steam turbine Power increase of the turbine available.
  • the first condensate mass flow correlates Partial flow with the bleed steam mass flow directly, so that each the larger the first partial flow, the greater the amount of required Tapping steam to preheat the first substream to achieve a desired temperature.
  • suitable Coupling the tapping steam flow with the first partial flow the need for bleed steam arises automatically. The process is special due to this self-regulating effect inexpensive and flexible to operate the steam power plant, especially adapted to increase the performance of the turbine.
