Definitions

  • the invention relates to a method for warm-drawing or warming up steam feed lines connected to steam turbine stages, in which warm-drawing steam is passed through a respective section to be drawn warm, a first steam feed line and a second steam feed line being passed through the first steam feed line in an operating flow direction of the steam given during turbine operation , and a method for dewatering steam feed lines connected to steam turbine stages, in which steam condensate is derived from a first and a second steam feed line through condensate drain lines, and a device for dewatering and warm-drawing steam feed lines connected to steam turbine stages, in which steam condensate from a first and a second Steam supply line can be derived through condensate discharge lines, and in which the steam supply lines connected to steam turbine stages can be drawn, in the case of a first section through a section to be heated Steam feed line and a second steam feed line, hot-drawing steam can be passed through, which can be conducted through the first steam feed line in an operating flow direction of the steam given during turbine operation.
  • steam turbines In a steam power plant or a gas and steam power plant, hot steam is sent through steam turbines, the rotors of which are set in motion by the temperature and pressure differences which arise as a result of the steam flow, thereby generating mechanical energy.
  • several steam turbine stages are generally used, which are designed for superheated steam with different temperatures and different pressures, ie high pressure, medium pressure and / or low pressure.
  • steam pressure, steam temperature and steam quality, ie steam purity are produced before entering the steam turbine.
  • steam feed lines through which superheated steam is fed to the steam turbine stages during operation, are hot-drawn with the help of heated warm-up steam before the steam turbines can be started up.
  • the steam supply lines are drawn warm either with the removal lines provided for drainage or specially installed warm drawing lines, through which the steam is discharged after passing through a steam supply line, for example into an atmospheric expansion device or to the turbine condenser.
  • a large amount of fresh steam must be used for warm drawing for each steam feed line, which must subsequently be deposited, for example, in the turbine condenser.
  • the hot-drawing lines must have a very large capacity in order to keep the start-up times of the steam turbine system short.
  • downstream discharge systems especially if the discharge to the turbine condenser takes place, must also be designed for large amounts of steam and at the same time be suitable for high steam temperatures in order to enable the steam turbines to start hot. Particularly safe precautions must be taken to prevent any malfunctions, in particular adequate temperature and pressure protection.
  • the condensate that forms as a result of the heating of cold steam lines is removed from the steam systems to ensure safe operation of the system.
  • the condensate is collected at the low points of the steam lines and discharged from the steam lines and passed, for example, into a start-up relaxer. Water that is separated off is either discarded, ie from the
  • the object is achieved with respect to the method for hot drawing in that the hot drawing steam after it has been passed through the section of the first steam supply line to be heated through a connecting line opened during the warm drawing process to the second steam supply line, then against the operating flow direction of the steam during turbine operation through the section of the second steam supply line to be heated passed and then discharged through the diversion of the second steam supply.
  • the warm-up steam flows through the connecting line to the second steam supply line after flowing through the steam supply sections of the first steam supply line and is only subsequently discharged through the bypass.
  • the superheated steam is thus used for both steam feed sections at the same time.
  • the capacity of the connecting line and the capacity of the drainage systems are independent.
  • the capacity of the connecting line is not affected by the limited capacity of the discharge systems.
  • the start-up times of the steam turbine system can be shortened considerably. Smaller sizes of the discharge system parts are therefore possible. Due to the lower temperature loads, it is sufficient to use a less expensive material for the discharge system parts.
  • the warming steam is not released into the atmosphere and discarded, which creates a heavy noise pollution of the environment, but remains essentially in the cycle. This also reduces the additional water requirement.
  • particularly critical line sections can also be included in the hot drawing, which would otherwise not be flowed through by the diversion steam due to the position of the connections of the diversions when starting.
  • a complete heating of the steam feed lines is achieved if the connecting line is connected to an end of the sections of the first steam line to be heated near the turbine and to an end of the second steam line to be drawn up close to the turbine.
  • the hot steam flows through the first steam turbine feed line until shortly before the first steam turbine stage, then through the connecting line up to the end near the turbine, to the second steam feed line and from there again in the opposite direction the section of the second pipe to be heated.

  • the entire steam supply lines can be heated with the same warm-up steam of the high-pressure area. This saves hot drawing steam and at the same time heats both steam supply lines with the high-pressure heating drawing steam at the higher temperature, only the steam supply lines to the high-pressure turbine stage being heated with the high-pressure heating drawing steam in the prior art.
  • the medium-pressure steam supply line and the low-pressure steam supply line are heated to higher than usual temperatures and the difference from the operating state is thus significantly reduced.
  • the medium-pressure and low-pressure steam supply lines must also be included if the temperature is designed accordingly.
  • any high-pressure steam feed diversions can be designed for a smaller amount of steam.
  • the connecting line can be used to discharge steam in the event of an overload of the turbine and can also be used as an additional discharge for the hot steam for a possible hot start.
  • the hot drawing steam is live steam, the hot drawing is very effective because the steam supply lines are brought to a very high temperature that is already close to the operating temperature.
  • the energy saving is very great if the first steam feed line is a medium pressure steam feed line to a medium pressure turbine stage and the second steam feed line is a low pressure steam feed line to a low pressure turbine stage.
  • the first steam feed line is a medium pressure steam feed line to a medium pressure turbine stage and the second steam feed line is a low pressure steam feed line to a low pressure turbine stage.
  • Superheated steam can also advantageously be used as the warming steam. After passing through the high pressure steam system, this is heated up again and reused. In this way, additional energy savings and steam savings are achieved.
  • the warm-up steam can be temporarily stored if the warm-up steam, after being passed through the section of the second steam feed line, is passed into a collecting container by a bypass connected to the second steam feed line.
  • the collecting container is a steam recovery system
  • the steam used for warming can be returned to the water / steam circuit of the thermal power plant and does not have to be separated or released into the atmosphere, which would lead to energy losses and environmental pollution.
  • a cost-saving use of the already existing systems is provided if the steam recovery system is a turbine condenser.
  • a very quick and at the same time complete warm-up is achieved by introducing live steam through the high-pressure steam supply line and superheated steam through the medium-pressure steam supply line, the live steam through the connecting line and through the section of the medium-pressure steam supply line up to a connection point for bypassing the medium-pressure steam supply line and the superheated line Steam is passed through a section of the medium pressure steam supply line to the connection point of the diversion and both steam flows are diverted through the diversion.
  • the reheated steam is thus used for the parts of the medium pressure steam supply system that are not reached by live steam, and both steam flows are discharged through the bypass.
  • a convenient control of the warm-up processes and a safe separation of the high-pressure steam supply line and the medium-pressure steam supply line or the low-pressure steam supply line is achieved in that the connecting line for hot drawing is opened by a motor-controlled valve. In this way, the warm drawing can be controlled as required and a more or less large warm drawing steam flow can be set.
  • the object directed to a method for dewatering steam feed lines connected to steam turbine stages is achieved in that steam condensate from the first steam feed line is fed to the steam condensate from the second steam feed line by means of a drainage connection line via an expansion tank and is discharged together with the steam condensate from the second steam feed line.
  • the loads on the downstream discharge systems are reduced.

Abstract

L'invention concerne un procédé pour réchauffer des conduites d'amenée de vapeur (1, 2) raccordées à des étages de turbines à vapeur (9, 10, 11). Ce procédé consiste à faire passer de la vapeur de réchauffage à travers une section à réchauffer d'une première conduite d'amenée de vapeur et d'une deuxième conduite d'amenée de vapeur, la vapeur étant acheminée à travers la première conduite d'amenée de vapeur dans un sens d'écoulement (4) donné de la vapeur lors du fonctionnement de la turbine, puis à évacuer la vapeur de réchauffage par des conduites de dérivation des conduites d'amenée de vapeur. L'objectif de cette invention est d'améliorer ledit procédé pour pouvoir réchauffer et purger rapidement et de manière sûre les conduites d'amenée de vapeur, dans le cas de systèmes d'évacuation conçus uniquement pour des capacités réduites. A cet effet, la vapeur de réchauffage est dirigée, après son passage à travers la section à réchauffer de la première conduite d'amenée de vapeur, dans une conduite de liaison (5), ouverte lors du réchauffage, raccordée à la deuxième conduite d'amenée de vapeur, elle est ensuite acheminée à travers la section à réchauffer de la deuxième conduite d'amenée de vapeur dans le sens inverse (6) au sens d'écoulement donné de la vapeur lors du fonctionnement de la turbine, puis elle est évacuée par la conduite de dérivation (7) de la deuxième conduite d'amenée de vapeur.
