Definitions
- the invention relates to a steam generator in which an evaporator fürlaufterrorism phenomenon angeord ⁇ net in a can be flowed through in an approximately horizontal Kleingasraum a gas evaporator fürlaufterrorism simulation comprising a number of parallel to the flow of a flow medium steam generator tubes summarized downstream of a number of each steam generator tubes flow medium side Exit collectors.
- the heat contained in the relaxed working medium or heating gas from the gas turbine is used to generate steam for the steam turbine.
- the heat transfer occurs in one of the gas turbine nachge ⁇ switched heat recovery steam generator in which typically a number of heating surfaces for water heating, for steam generation and arranged for steam superheating.
- the heating surfaces are maral ⁇ tet in the water-steam cycle of the steam turbine.
- the water-steam cycle usually includes several ⁇ re, z. B. three, pressure levels, each pressure stage can have a Ver ⁇ steamer Schu Structure.
- a continuous steam generator In contrast to a natural or forced circulation steam generator, a continuous steam generator is not subject to pressure limitation, so that it is possible for fresh steam pressures far above the critical pressure of water (P K ⁇ x 221 bar) - where no differentiation of the phases water and steam and thus no phase separation is possible. can be designed.
- a high fresh steam pressure promotes a high thermal efficiency and thus low C0 2 emissions of a fossil-fueled power plant.
- a continuous steam generator in comparison to a circulating steam generator a simple construction and is thus produced with very little effort.
- the use of a fertilizer designed according to the continuous flow principle as a heat recovery steam generator of a gas and steam turbine plant is therefore to achieve a high overall efficiency of the gas and steam turbine plant in a simple design be ⁇ particularly favorable.
- a heat recovery steam generator in horizontal design, in which the heating medium or heating gas, ie the exhaust gas from the gas turbine, is guided in approximately horizontal flow direction through the steam generator.
- a steam generator which has a particularly high degree of flow stability when designed as a continuous-flow steam generator with comparatively low constructional and design complexity, is known, for example, from WO 2004/025176 A1.
- This steam generator has an evaporator pass-through heating surface which comprises a number of steam generator tubes or evaporator tubes connected in parallel to the flow through a flow medium.
- a continuous steam generator is operated in low-load operation or during start-up with a minimum flow of flow medium in the evaporator tubes in order to ensure reliable cooling of the evaporator tubes and to avoid possible formation of steam in the evaporator throughflow heating surface upstream of the economizer heating surface.
- This minimum flow is not completely vaporized at start or in low-load operation in the evaporator tubes so that, when such an operation of the evaporator tubes ⁇ art at the end still unevaporated flow medium is present. In other words, in this mode of operation, a water-steam mixture emerges from the evaporator tubes.
- the invention is therefore an object of the invention to provide a continuous steam generator of the above type, which allows for low production costs even in start-up or low load operation, a particularly high operational Flexibi ⁇ quality and thus in particular also kept low start-up and load change times.
- each outlet header each comprises an integrated Wasserabscheiderelement through which the respective outlet collector is connected to the flow medium side with a number of nachge ⁇ switched superheater tubes a Kochhitzerschreib construction.

- a superheater heating surface connected downstream of the evaporator throughflow heating surface should be able to be used for evaporation of the flow medium if necessary, ie just for starting or low load purposes.
- the evaporation end point should be slidable into the superheater heating surface.
- the transition region between the evaporator fürlaufterrorism behavior and the fol ⁇ ing superheater heating should be designed such that a feed of water into the superheater heating into it is possible.
