Definitions

  • the present invention relates to a steam power plant with cooling tower and flue gas purification plant and with a wastewater treatment plant for process wastewater and in particular for recovering process water.
  • the invention furthermore relates to a method for operating a steam power plant with cooling tower and flue gas purification plant.
  • a steam power plant substantially comprises a fired boiler, a steam turbine, a water-steam circuit, a condenser, a cooling tower and a flue gas purification plant.
  • the working medium used in the water-steam circuit in steam power plants is deionized water which is produced in a deionization plant using ion-exchange resins.
  • the deionized water is evaporated in the steam generator and passed into the steam turbine where it is expanded.
  • the energy released during expansion is transferred via a shaft to the generator.
  • the expanded steam is then fed to a condenser, and the liquid phase is condensed.
  • an evacuation system is connected to the condenser, which system produces a vacuum in the condenser when the steam power plant is started up, and maintains it during operation.
  • the vacuum increases steam turbine efficiency and removes non-condensable gases from the liquid stream.
  • various contaminants may be introduced into the working medium.
  • various substances are added to the working medium for conditioning or purification.
  • the contaminants and additives in particular include ammonia, calcium, magnesium, sodium, potassium, chlorides, nitrates, sulfates (sulfuric acid) and silicon dioxide.
  • the working medium contaminated by contaminants or additives must be discharged from the water-steam circuit as process wastewater, since the contaminants stand in the way of direct reuse as a working medium in the water-steam circuit.
  • Ammonia serves as an alkalizing agent for conditioning the feed water. Through the addition of ammonia, an increase in the pH value of the working medium may be achieved, whereby the relative corrosion rate of the feed water is reduced. Since the distribution coefficient of ammonia in liquids and steam is different, locally markedly elevated ammonia concentrations may occur in system parts involving evaporation and condensation processes.
  • Process wastewaters arise at various points in the steam power plant. A large proportion of contaminated water arises in the form of the desalination stream from the boiler drums in the evacuation system. On startup and shutdown, deficiencies (due to additional feeding of working medium) and excesses (due to discharge of working medium) of the working medium must be compensated. Moreover, process wastewaters arise due to water samples being taken and leaks in the water-steam circuit. As a result of the above-stated water losses, the water-steam circuit must be continuously additionally fed with deionized water (DIW). Backwashing and regeneration processes in the deionization plant and condensate purification also result in process wastewaters.
  • DIW deionized water
  • Drainage is performed for example during ongoing operation from pipes in which condensate has collected and which have been closed for an extended period. To this end, the pipes are opened briefly and thus drained. Water is then lost from the water circuit, which has to be replaced by make-up water (DIW). Drainage also in particular arises to a greater extent on startup and shutdown of the steam power plant, since for example on shutdown of the steam power plant the steam in the water circuit gradually condenses and the resultant liquid water must not be allowed to stand in the plant parts, in particular in the heating surfaces. On shutdown, more water is drained from the water circuit than is replenished, until ultimately no more water is replenished.
  • DIW make-up water
  • the process wastewaters from the water-steam circuit are, depending on quality, returned to the water-steam circuit or discharged into the cooling tower or the industrial wastewater system.
  • Cooling tower blowdowns have in the past been discharged into public watercourses via a receiving stream.
  • An exemplary 2 ⁇ 1050 MW fossil fuel-fired steam power plant according to the prior art with natural draft cooling tower and a wet limestone flue gas purification plant produces up to 100,000 tonnes of process wastewater per year in base-load operation, which has to be discharged into public watercourses. Just about half of this amount is accounted for by the cooling tower.
  • the object of the invention is therefore that of providing a steam power plant in which the total water consumption of a steam power plant, the pollutant load in the remaining wastewater, in particular the wastewater from the flue gas purification plant, and the consumption of deionized water are minimized.
  • the object of the invention is furthermore that of providing a method for operating a steam power plant in which total water consumption is minimized.
  • the apparatus-related object of the invention is achieved by the features in the independent apparatus claim.
  • the fossil fuel-fired steam power plant here comprises a water-steam circuit, a cooling water circuit, a cooling tower and a flue gas purification plant.
  • a fossil fuel-fired steam generator, a steam turbine, and a condenser are connected into the cooling water circuit.
  • a cooling tower and the condenser are interconnected in the cooling water circuit in such a manner that expanded steam from the water-steam circuit is condensable in the condenser by heat exchange with the cooling water circuit.
  • the flue gas from the fossil fuel-fired steam generator may be purified, for example of carbon dioxide (CO 2 ), in the flue gas purification plant.
  • process water may be supplied to the flue gas purification plant and process wastewater may be discharged therefrom.
  • the flue gas purification plant is connected to the cooling water circuit in such a manner that the process water required for flue gas purification may be drawn from the cooling water circuit.
  • the flue gas purification plant is connected to a wastewater treatment plant comprising an evaporator for discharge of process wastewater. Purified process wastewater may be produced by the wastewater treatment plant.
  • the invention is here based on the consideration, on the one hand, of using water from the cooling water circuit for flue gas purification and, on the other hand, of purifying the process wastewater contaminated by the flue gas purification by evaporation in the wastewater treatment plant, so giving rise to cleaner process wastewater.
  • the raw water requirement of the steam power plant may be reduced by the amount of the additional water requirement of the flue gas purification plant.
  • the consumption of chemicals may also be lowered, whereby the environmental balance of the power plant may be made more resource-efficient.
  • the flue gas purification plant is connected to the cooling water circuit downstream of the cooling tower in such a manner that cooling tower blowdown water may be used as process water for flue gas purification.
  • Cooling tower blowdown is wastewater which necessarily occurs in large volumes as contaminated process water in a power station with a cooling tower and is thus always available. The total wastewater volume is reduced as a consequence since the process water is additionally concentrated in the flue gas purification plant.
  • concentration may however also be considered disadvantageous since the process wastewater is repeatedly concentrated in the flue gas purification plant.
  • the salt and heavy metal loading and the input of pollutants by flue gas purification into the process wastewater may reach very high levels as a consequence.
  • An improved and particular embodiment of the fossil fuel-fired steam power plant therefore proposes supplying the flue gas purification plant with a process water which is connected from the cooling water circuit upstream of the cooling tower and upstream of a cooling tower make-up water treatment plant. Said process water has not yet been treated in the cooling tower make-up water treatment plant and is thus untreated.
  • the water is in each case concentrated only once in the flue gas purification plant and it is therefore easier to comply with limit values for chloride, sulfate and heavy metals. Furthermore, the additional input of chloride into the process wastewater due to precipitation with FeCl 3 during cooling tower make-up water treatment also does not occur. Since the cooling tower blowdown is not put to any further use in this case, it can be more highly concentrated. The volume of make-up water for the cooling tower falls because the level of blowdown is lower. As a consequence, the water consumption of the steam power plant is reduced.
  • any solids may however have to be removed from the untreated cooling tower make-up water, for example by a settling tank.
  • the flue gas purification plant is connected to the cooling water circuit upstream of the cooling tower and to a cooling tower make-up water treatment plant, such that cooling tower water treated for use in the cooling tower may be used as process water for flue gas purification.
  • cooling tower make-up water is used as process water, said water is concentrated only once, whereby it is easier to comply with limit values.
  • the chloride content of the water is slightly raised. Since the cooling tower blowdown is not put to any further use, it can be more highly concentrated. As a consequence, the volume of make-up water for the cooling tower falls because the level of blowdown is lower. As a consequence, the water consumption of the power plant is reduced. This measure may also be necessary if the total discharge volume for wastewater into the receiving stream is fixed.
  • the wastewater treatment plant is connected to a deionization plant included in the water-steam circuit.
  • purified process wastewater from the wastewater treatment plant may be introduced into the deionization plant.
  • the purified process wastewater thus contributes to additionally feeding the water-steam circuit, thereby on the one hand saving raw water for additional feeding and on the other hand reducing the load on the deionization plant since less deionized water (DIW) need be produced.
  • DIW deionized water
  • the wastewater treatment plant is connected to a cooling tower make-up water treatment plant included in the water-steam circuit.
  • purified process wastewater from the wastewater treatment plant may be introduced into the cooling tower make-up water treatment plant.
  • the wastewater treatment plant is advantageously furthermore also connected to the condensate purification plant, the evacuation system and sampling point for introduction of contaminated process wastewaters from the water-steam circuit into the wastewater treatment plant.
  • All the process wastewaters from the condensate purification plant are recirculated into the water-steam circuit via the wastewater treatment plant.
  • the process wastewaters which arise during startup for boiler flushing are recovered as a consequence. Since boiler flushing is performed with DIW, the discarded process wastewaters are of good quality.
  • the auxiliary boiler is likewise fed with DIW, for which reason the process wastewater (blowdown) is of high quality.
  • the process wastewater from the auxiliary boiler must be expected to have elevated ion concentrations and to be contaminated with iron particles.
  • the streams which may be recirculated into the water-steam circuit comprise low levels of contaminants (for example iron particles and ammonia). Before recirculation into the water-steam circuit, these streams must therefore be purified using the condensate purification plant. This may proceed by feeding into the riser tube of the condenser upstream of the condensate purification plant. In the case of recirculation upstream of the condensate purification plant, the maximum operating temperature of the ion exchangers in the condensate purification plant must be borne in mind. Under certain circumstances, the recirculated streams must firstly be cooled. The service life of the condensate purification plant is reduced by the higher ion loading. The volume of DIW which has to be provided by the deionization plant is lower, since less make-up water is required.
