Definitions
- the invention relates to a method for evacuation a turbine condenser, in particular during start-up operation. It further relates to a device for implementation of the procedure.
- the turbine or main capacitor is evacuated. It is by means of a so-called Start-up steam jet, in turn, according to the jet pump principle is supplied with motive steam, the turbine condenser and thus the steam turbine plant within z. B. evacuated from 1.0 bar to approx. 0.3 bar for half an hour. The the start-up jet pump leaving the steam-air mixture on the pressure side is conveyed to the outside via a pipeline. The Piping must be adjusted for the mixing temperature the steam-air mixture is designed and is due Environmental requirements to be met with a silencer equip.
- the main disadvantage here is that usually the Water-steam cycle of the steam turbines extracted motive steam is lost, so that in the feedwater circuit of the Turbine condenser a corresponding amount of feed water must be refilled. This feed water loss increases with increasing number of starts and requires additional Costs for the necessary feedwater treatment.
- the invention is therefore based on the object, a method for evacuating a turbine condenser, in particular during start-up operation, with which the specified Disadvantages avoided in a particularly simple manner are. Furthermore, one for carrying out the method particularly suitable device can be specified.
- the driving steam condensing in the auxiliary condenser as condensate the feedwater circuit of the turbine condenser and thus the steam turbine plant fed again.
- the air contained in the motive steam is expediently removed from the auxiliary capacitor.
- the heating of the over the auxiliary capacitor keeps the flow of condensate within required limits, is the means of a condensate pump on the auxiliary capacitor guided condensate flow to a large extent of approx. 75% passed over the condenser tubes of the main capacitor.
- the cooling water cooling of the main condenser becomes Re-cooling of the guided over the auxiliary capacitor condensate partial stream used.
- the comparatively small share of about 25% of the condensate flow, d. H. the subsidized per unit time Condensate thus stands for the start-up operation required cooling of the drainage systems from the steam turbine to disposal.
- the advantages achieved by the invention are in particular in that the water-steam cycle of a steam turbine removed and for evacuation of a turbine condenser inserted motive steam by its introduction into the Auxiliary capacitor of a steam turbine plant the cycle again is supplied. This is an undesirable Nachspeisung avoided by feed water in the circulation. About that In addition, a previously common silencer in steam jet air pump system for turbine and condensate venting additionally saved.
- a main or turbine condenser 1 of a (not shown) Steam turbine plant is on the output side over the Condensate collector 2 connected to a condensate line 3, via a condensate pump 4 to an auxiliary capacitor. 5 connected on the input side.
- On the output side is the Auxiliary capacitor 5 via a condensate line 6 with the Main capacitor 1 connected.
- a circulation control valve 7 for setting the for a start-up operation required amount of cooling condensate.
- To the condensate line 6 is an at z.
- auxiliary capacitor 5 accumulating condensate K is about a condensate line 10 in the condensate collector 2 of the main capacitor 1 led.
- the condensate line 10 via two branch lines 10a and 10b, in each of which a shut-off valve 11a, 11b, with a first pressure stage 5a or with a second pressure stage 5b of the auxiliary capacitor 5 connected.
- a branch line for condensate return 10c of the condensate line 10 leads into the main capacitor 1, in which an exhaust steam line 12 from the (not shown) Steam turbine opens.
- the first and second pressure stage 5a, 5b of the auxiliary capacitor 5 is in each case a further operating jet pump 20a or 20b assigned.
- the operating jet pumps 17a, 20a and 17b, 20b are redundant.
- the operating jet pumps 17a, 17b and 20a, 20b are each connected via a branch line 21a, 21b and 22a, 22b, in each of which a shut-off valve 23 is connected to a common motive steam line 24.
- a shut-off valve 23 is connected to a common motive steam line 24.
- the start-up jet pump 19 via a branch line 25, in turn, a check valve 26 is connected to the motive steam line 24.
- the motive steam line 24 is another shut-off valve 27, which is taken over this guided motive steam D T in a manner not shown a water-steam cycle of the steam turbine.
- the turbine condenser 1 is first evacuated.
- motive steam D T is guided.
- the amount of motive steam D T guided during the Ahfahr lies over the motive steam line 24 and via the branch line 25 per unit time is determined by the start-jet pump 19.
- the start-up jet pump 19 is preferably connected on the pressure side via a connecting line 28 to the second pressure stage 5b of the auxiliary capacitor 5. While the motive steam D T condenses in the auxiliary capacitor 5, the entrained by the driving steam D T air L is discharged via a vent line 29 from the auxiliary capacitor 5 into the atmosphere. The condensing in the auxiliary capacitor 5 driving steam D T is introduced as condensate through the condensate line 10 in the condensate collector 2 of the main capacitor 1 and thus in the circuit.
- the cooling water K ' which warms up during the heat exchange with the motive steam D within the auxiliary condenser 5, leaves the auxiliary condenser 5 via the condensate line 6.
- the actuating or Control valve 7 To set the amount of condensate substream or cooling water K' carried per unit time via the auxiliary condenser 5, the actuating or Control valve 7. During start-up operation, the amount of cooling water K 'is set to about 50% to 70% of the rated condensate amount.
