Definitions
- the invention relates to a waste heat steam generator in use behind a gas turbine, at least one drum being provided, which is integrated in a circulation system consisting of at least one downpipe, at least one evaporator heating surface and at least one riser pipe.
- Waste heat steam generators are usually designed in two types, e.g. with natural circulation or forced circulation.
- natural circulation the evaporator bundles are arranged in a horizontal flue gas duct in a vertical installation position and connected to at least one steam drum via downpipes and riser pipes.
- the heating surface tubes from the superheater and economizer or from various other heating surfaces, if present, can be designed in a horizontal and / or vertical arrangement.
- the heating surface pipes from the superheater, evaporator and economizer or other heating surfaces, if present, are arranged in a vertical flue gas duct in a horizontal installation position.
- the evaporator heating surfaces are connected to at least one steam drum via downpipes, circulation pumps and risers.
- the circulation pumps which ensure the water circulation in the evaporator, are associated with a cost and labor in the construction of the system and also form a disruptive factor.
- the object of the present invention is to provide a waste heat steam generator which is simulated by a gas turbine and has the advantage that the water circulation is ensured without the use of a circulation pump.
- an injector is provided in the downpipe system, which additionally feeds water in the flow direction in the downpipe system during the start-up phase.
- the acceleration of the water circulation in the start-up phase can be achieved by an injector arranged in the riser pipe system, which feeds water into the riser pipe system in the flow direction.
- a device for feeding steam, steam water mixture, gases such as nitrogen or the like into the riser pipe system is provided to accelerate the water circulation in the start-up phase.
- a lockable connecting line can be provided between the inlet and the outlet header of the evaporator heating surfaces in order to accelerate the water circulation in the start-up phase.
- the waste heat steam generator in question is provided in a vertical version with an evaporator heating surface 1, a drum 2, a down pipe system 3, a riser pipe system 4 and a feed line 5 with a feed pump 6.
- the drum 2 is connected on the water side to the downpipe system 3, which opens into an inlet header 7 via a lower stroke 29, to which the pipe system of the evaporator heating surface 1 is connected.
- the term "lower stroke” is to be understood so that the downpipes 3 are led down to a level which is lower than the inlet manifold 7 of the evaporator heating surface 1, so that the water flows from the bottom up before it enters the collector.
- the "lower stroke” can thus be understood as a kind of water bag.
- the evaporator heating surface 1 is connected on the outlet side to an outlet header 8, into which the riser pipe system 4 opens, which is connected to the steam chamber of the drum 2 via an overtravel 9, or directly via a pipe system 10 to the water chamber 11 of the drum 2.
- overstroke is to be understood such that the steam / water mixture is introduced into the drum 2 higher than the level of the water in the drum.
- the feed pump 6 promotes the like from a feed water tank. Via the feed line 5 water into the water space 11 for make-up.
- an injector 12 is provided in the downpipe system 3, which is connected to a shut-off device 14, e.g. a valve, a tap or the like.
- a shut-off device 14 e.g. a valve, a tap or the like.
- provided line 13 is connected to the feed line 5.
- a second variant provides a pump 16 in a bypass line 15 which connects the downpipe system 3 with an injector 17 Riser pipe system 4 connects.
- This pump 16 feeds boiler water into the riser pipe system 4 in its direction of flow, as a result of which the water circulation is dynamically excited in the start-up phase and the excitation can be switched off again after the stationary circulation state has been reached by switching off the pump 16.
- the riser pipe system 4 can be fed from a line 18 in which a shut-off device 19, e.g. a valve, a tap or the like. steam, nitrogen or another gas. This measure increases the thermosiphon effect and ensures an acceleration of the circulation process in the start-up phase.
- a shut-off device 19 e.g. a valve, a tap or the like. steam, nitrogen or another gas.
- a fourth variant sees one through a shut-off device 21, e.g. a valve, a tap or the like.
- lockable line 22 which connects the inlet header 7 to the outlet header 8 of the evaporator heating surface 1.
- the installation of such a lockable connecting line 22 between at least one inlet and at least one outlet header 7 or 8 of the evaporator heating surfaces 1 ensures that when the first vapor bubbles are formed, they stimulate the water circulation in the start-up phase by direct discharge into the riser pipe system 4.
- thermosiphon effect of the water circulation can be advantageously influenced by suitable dimensioning of the pipe system of the evaporator heating surfaces 1 and of the downcomer and riser pipe systems 3 and 4.
- the waste heat boiler design can be retained in the known embodiment and the use of circulation pumps in the circuit can be dispensed with.
- the evaporator heating surface 1 is arranged in a horizontal arrangement in an exhaust gas duct 23, into which the exhaust gases of one or more gas turbines flow in the direction of arrow A, above and / or below the evaporator heating surface 1, a superheater heating surface 24 can also be provided in a horizontal arrangement, which is connected on the inlet side to the steam chamber 26 of the drum 2 via an inlet collector 30 and a line 25 and on the outlet side leads to the turbine via an outlet collector 31 and a line 27 provided with a shut-off device 28 .
