Definitions
- heated feed water can be drawn from the medium-pressure system, from the high-pressure system or from both systems.
- the removal essentially depends on the heat required for heating up the condensate and on the plant efficiency that should at least be maintained when the gas turbine is operated as a backup oil operation only.
- the heated feed water or hot water is expediently in a two-pressure system, i.e. H.' in a two-pressure system from a high-pressure drum and in a three-pressure system or in a three-pressure system from the high-pressure drum and / or from a medium-pressure drum as feed water partial flow.
- the partial flow can also be withdrawn at the outlet of the high-pressure economizer or the medium-pressure economizer.
- the pressure of the low-pressure system can also be raised in order to shift the heat contained in the flue gas from the low-pressure system to the condensate preheater downstream of the flue gas side. It is essential that the heated feed water in the form of a feed water partial stream removed from the water-steam cycle at a suitable point without prior heating, i.e. is added to the cold condensate without heat exchange in an additional heat exchanger.
- Inlet temperature is required. Standardization is also possible as a result of the operating range being expanded in a particularly effective manner in terms of circuitry. Furthermore, the investment costs are particularly low.
- FIG. 1 schematically shows a gas and steam turbine system designed for a change of operation from gas to oil with a hot water mixing device
- FIG. 2 shows the mixing device according to FIG. 1 on a larger scale with a number of spray heads
- FIG. 3 shows a detail III from FIG. 2 on a larger scale with a spray head having a valve.
- the gas and steam turbine system 1 comprises a gas turbine system 1 a and a steam turbine system 1 b.
- the gas turbine system 1 a comprises a gas turbine 2 with a coupled air compressor 4 and a combustion chamber 6 connected upstream of the gas turbine 2 and which is connected to a fresh air line 8 of the air compressor 4.
- a fuel line 10 opens into the combustion chamber 6 and can be used to supply gas or oil as the fuel B to the combustion chamber 6. This is burned with the supply of compressed air L to the working fluid or fuel gas for the gas turbine 2.
- the gas turbine 2 and the air compressor 4 and a generator 12 sit on a common turbine shaft 14.
- the steam turbine system 1b comprises a steam turbine 20 with a coupled generator 22 and, in a water-steam circuit 24, a condenser 26 connected downstream of the steam turbine 20 and a waste heat steam generator 30.
- the steam turbine 20 has a first pressure stage or a high pressure part 20a and a second pressure stage or a medium pressure part 20b and a third pressure stage or a low-pressure part 20c, which drive the generator 22 via a common turbine shaft 32.
- An exhaust pipe 34 is connected to an inlet 30a of the heat recovery steam generator 30 in order to supply working fluid or flue gas AM relaxed in the gas turbine 2 to the heat recovery steam generator 30.
- the flue gas AM from the gas turbine 2 which cools down along the heat recovery steam generator 30 as a result of indirect heat exchange with condensate K and feed water S conducted in the water-steam circuit 24, leaves the heat recovery steam generator 30 via its outlet 30b in the direction of a chimney (not shown).
- the heat recovery steam generator 30 comprises, as heating surfaces, a condensate preheater 36 which is fed with condensate K from the condenser 26 via a condensate line 38 into which a condensate pump 40 is connected.
- the condensate preheater 36 is guided on the outlet side to the suction side of a feed water pump 42.
- a mixing device 44 with a tubular hot water mixer 46 is connected into the condensate line 38.
- the feed water pump 42 is designed as a high-pressure feed pump with medium pressure extraction. It brings the condensate K to a pressure level of approximately 120 bar to 150 bar, which is suitable for a high pressure stage 50 of the water-steam circuit 24 assigned to the high pressure part 20a of the steam turbine 20. About the The medium pressure is removed from the condensate K by means of the feed water pump 42 to a pressure level of approximately 40 bar to 60 bar suitable for a medium pressure stage 70 assigned to the medium pressure part 20b of the steam turbine 20.
- the condensate K which is fed via the feed water pump 42 and is referred to as feed water S on the pressure side of the feed water pump 42, is partly fed at high pressure to a first high-pressure economizer 51 or feed-water preheater and via this to a second high-pressure economizer 52. This is connected on the output side to a high-pressure drum 54 via a valve 57.
- the feed water S is also partially fed to a feed water preheater or medium pressure economizer 73 at a medium pressure via a non-return flap 71 and a valve 72 connected downstream of this. On the output side, this is connected to a medium-pressure drum 75 via a valve 74.
- the condensate preheater 36 is connected on the output side to a low-pressure drum 92 via a valve 91.
- the medium pressure drum 75 is connected to a medium pressure evaporator 76 arranged in the heat recovery steam generator 30 in order to form a water-steam circulation 77.
- an intermediate superheater 78 is connected to the medium-pressure drum 75, which is led on the outlet side (hot CLOSE) to an inlet 79 of the medium-pressure section 20b and in the inlet-side (cold CLOSE) one with an outlet 80 of the high-pressure section 20a of the steam turbine 20 connected steam line 81 is guided.
- the feed water pump 42 is connected via two valves 55, 56 as well as via the first high-pressure economizer 51 and the downstream downstream of the feed water side and inside the waste heat steam generator 30 on the flue gas side o O IV) rv> P 1 c ⁇ o C ⁇ o C ⁇ o c ⁇ o rt ⁇ NSP o £ rt P- P ⁇
- a valve 102 with an upstream check valve is used via a partial flow or hot water line 101
- adjustable partial flow tS of heated feed water S ' is fed to the mixing device 44, 46 and in the interior thereof
- the partial flow tS of heated feed water S ' is preferably taken from the high-pressure drum 54 on the water side via a valve 106.
- the heated feed water S ⁇ can be taken as an adjustable partial flow tS via a valve 107 from the first high-pressure economizer 51 or via a valve 108 from the second high-pressure economizer 52.
- an adjustable partial flow tS can also be taken from the medium-pressure economizer 73 on the output side via a valve 109 or the medium-pressure drum 75 on the water side via a valve 110 heated feed water S ⁇ .
- the admixture of the partial flow tS to the condensate K by injecting the heated feed water S conducted via the hot water line 101 into the cold condensate K leads to a targeted evaporation and subsequent condensation of the water-steam mixture formed in the mixing device 44, 46.
- the temperature TS of the partial flow tS when it is removed as heated feed water S from the high-pressure drum 54 is, for example, 320 ° C.
