Definitions

  • the present invention relates to a system for feeding makeup water and preheating it into a water-steam cycle in a steam power plant. Furthermore, the present invention relates to a method for degassing make-up water in a water-steam cycle in a steam power plant.
  • the water-steam cycle When decoupling process steam / heat in steam power plants, the water-steam cycle must be refilled by means of the continuous supply of make-up water due to leaks and losses of process steam / condensate.
  • the make-up water is usually treated, but not degassed.
  • the additional water contains dissolved foreign gases, which must be expelled again in a degasser of the steam power process. In order to increase the process efficiency, the additional water must be preheated before entering the degasser.
  • make-up water also called makeup water
  • makeup water a conventional degassing
  • make-up water can be fed directly into a turbine condenser or into a low-pressure preheater.
  • this variant can only be used for smaller amounts of make-up water.
  • FIG. 2 Another conventional system for supplying make-up water is shown in a water-steam cycle.
  • the condensate from a conventional condenser 201 is pumped through a conventional condensate pump 202 into a container 204.
  • a mass flow m z of the make-up water is mixed in via a conventional supply line 203.
  • the water mixture is then pumped by another condensate pump 205 through conventional heating devices 206, 208 of the water-steam cycle into the conventional degassing device 209.
  • the water mixture is not degassed due to the additional water content and thus contains dissolved and corrosive media (eg oxygen), all containers, lines and fittings, including the container 204, must be made of corrosion-free stainless steel up to the conventional degassing device.
  • the water is supplied to a conventional evaporator 207.
  • DE 10 2005 040 380 B3 discloses a condensation process. Abdampf of a turbine is fed to an air-cooled condenser for condensation. The condensate recovered in the condenser is pre-heated in a Kondensat stiir Anlagenrmnote before it is fed from a feed pump upstream of the turbine evaporator. The condensate is heated by a partial steam flow of the turbine. Parallel to the condensate warm-up stage, a degasser for degassing make-up water is connected. A partial steam flow from the condenser is condensed by supplying the colder additional feed water. The additional feed water is heated and degassed at the same time. The degasser thus serves as a second downstream condensation stage.
  • EP 1 093 836 A1 discloses a degassing system for power plants.
  • the degassing system is used for gasification of an additionally supplied make-up water, which is connected as part of the condensation system of the power plant with a capacitor. From a make-up tank additional water is fed directly to the degassing system.
  • EP 0 158 629 A2 discloses a steam cycle for steam power plants.
  • steam from a turbine is cooled and condensed.
  • the steam heat exchanger is supplied with additional water from a feedwater degasser.
  • WO 2012/090778 A1 discloses a condensate flow rate control apparatus and a power plant control method.
  • a power plant is equipped with a condensate flow rate control device.
  • a breather is provided in which a condensate generated in a condenser is supplied via a breather water level control valve and into which the bleed steam from a steam turbine is introduced.
  • the condensate flow rate control device has a water level adjusting device for performing the condensate flow rate control.
  • the water level adjusting means adjusts the pressure in the condensate flow path from the breather water level adjusting valve to the breather so that input frequency fluctuations are suppressed or so that the output value of a generator corresponds to the input requested load changes, thereby adjusting the discharge steam amount from the steam turbine.
  • This object is achieved with a system for supplying makeup water via an extra condensate make-up water heater of a water-steam cycle in a steam power plant and with a method for degassing make-up water in a downstream degasser of a water-steam cycle in a steam power plant according to the solved independent claims.

  • This water is called condensate.
  • About the condensate pumps and preheaters or heating devices through the water is temporarily stored, for example, in a feedwater tank and then fed via another condensate pump again the steam boiler or the evaporator.
  • the water is supplied to the degassing apparatus to remove harmful gases such as e.g. largely remove corrosive oxygen or carbon dioxide.
