Definitions
- the invention relates to a heat recovery steam generator, in particular in the Use behind a gas turbine, with at least one drum in one Natural circulation system consisting of at least one downpipe, at least a horizontal evaporator heating surface including at least one with the inlet pipe connected to the downpipe and at least one Outlet collector and at least one with the outlet collector connected riser pipe, the evaporator heating surface in one ascending hot gas flow is arranged.
- Such a heat recovery steam generator is known from EP 0 357 590 B1.
- the Evaporator heating surface is dependent on the medium to be evaporated or the Mixture of medium to be evaporated and evaporated medium from below flows upwards, d. H. in direct current.
- a steam start is required to start the water circulation in the steam generator Ensure or accelerate the start-up phase.
- Injector arranged, the partial flow of water with the desired Feeds the flow direction into the down pipe system and / or riser pipe system.
- a device for feeding steam is Steam-water mixture, gases such as nitrogen or the like in the riser pipe system intended.
- a lockable connecting line is provided as Traction aid between at least one entry and exit collector each Evaporator heating surface a lockable connecting line is provided.
- This object is achieved in that the evaporator heating surface in Counterflow to the hot gas flow from the medium to be evaporated or Medium / medium vapor mixture is flowed through and the inlet header with an understroke of the downpipe is connected.
- the Water space 1a of a drum 1 via at least one downpipe existing downpipe system 2 with sub-stroke 3 an inlet header 4 Water supplied.
- the water enters one in one Evaporator heating surface 5 arranged in dashed lines with dashed lines K their horizontally extending tubes 5a (horizontal Evaporator heating surface).
- the water or the flows in the heating surface 5 Forming water-steam mixture from top to bottom through the horizontally extending tubes 5a and then enters one below the Entry collector 4 lying collector 6 and is from this over a riser pipe system 7 consisting of at least one riser pipe Water chamber 1a of the drum 1 is supplied.
- the heating surface 5 is in one arranged rising hot gas stream HG, d. H. the water or the Water-steam mixture flows in countercurrent to the rising hot gas HG down.
- the first steam is in the bottom tubes of tubes 5a of the evaporator heating surface.
- the Steam can enter the riser pipe system 7 directly and ensures that required density difference between the content of the or the downpipes Down pipe system 2 and the content of the riser pipe or pipes Riser pipe system 7.
- the Lower stroke 3 to below the position level of the outlet header 6.
- the tubes 5a are provided with fins 8.
