The high pressure cylinder of steam-turbine unit and the steam inlet condition of intermediate pressure cylinder are monitored simultaneously；
S2, will be isolated with the separator of high pressure cylinder, intermediate pressure cylinder connection, to adjust and reduce high pressure cylinder
With intermediate pressure cylinder steam inlet condition.
The cylinder temperature acceleration cooling method of steam turbine for nuclear power station high intermediate pressure cylinder provided in an embodiment of the present invention, one side steam turbine
Unit first idle running after off-the-line is compared with the existing technology for a period of time in order to reinforce cooling of the Low Temperature Steam to cylinder temperature
Extend steam-turbine unit and shut down the idle running time to reinforce cooling of the Low Temperature Steam to cylinder temperature, on the other hand passes through isolation vapour again
Water separator/heater reduces high intermediate pressure cylinder steam inlet condition further to strengthen to cylinder cooling effect, so that shutting down cylinder temperature when maintenance
The time for being cooled to certain temperature greatly shortens, and is finally reached the purpose for accelerating cylinder temperature cooling, saves the critical path duration.
Preferably, in the steam-turbine unit idle running the step of；The throttle (steam) temperature of high pressure cylinder is set as 140 DEG C to 150
℃；The throttle (steam) temperature of intermediate pressure cylinder is set as 145 DEG C to 155 DEG C.It is highly preferred that for the ease of reinforcing Low Temperature Steam to the cold of cylinder temperature
It but, is 144 DEG C in 25.769kg/s, throttle (steam) temperature into vapour flow control by high pressure cylinder；150 DEG C of the throttle (steam) temperature of intermediate pressure cylinder.
Further, in the step of controlling the idle running time of steam-turbine unit, the idle running time is set as 60
Minute was to 120 minutes.The idle running time is preferably set as 56 minutes, further strengthens to cylinder cooling effect, so that inspection
The time that shutdown cylinder temperature is cooled to certain temperature when repairing greatly shortens, to achieve the purpose that accelerate cylinder temperature cooling, to save
The critical path duration.
The present embodiment is illustrated by taking L3/4 unit as an example.Specifically, it has repeatedly been adopted in stopping process since Self-debugging
With shutdown idle running mode, in practice it has proved that idle running, which shortens cooling time to unit, certain effect.Table 1 is that L300 is small
It repairs and is compared with L301 overhaul shutdown cylinder temperature trend, the means such as L300 light maintenance use zero load 56 minutes, and L301 overhaul shutdown phase
Idle running is not carried out, and data statistics discovery L300 light maintenance shuts down cylinder temperature and is cooled to 150 DEG C of time ratio L301 overhaul shortening about
7.5h。
The cooling data comparison of cylinder temperature is shut down in table 1L300 light maintenance and L301 overhaul
Idle running 75 minutes after L401 overhaul unit trip, 174 DEG C of decline when during which high pressure cylinder center housing temperature is from off-the-line
To beating 154 DEG C before lock, 20 DEG C are had dropped, cooling effect is obvious.It compares L301 overhaul to shut down without zero load, off-the-line beats cylinder temperature before lock
175 DEG C, naturally cool to 154 DEG C of time-consuming about 34h.
In addition, when L3/4 steam turbine idle running, high pressure cylinder into 144 DEG C of steam flow amount 25.769kg/s, throttle (steam) temperature, in
180 DEG C of cylinder pressure throttle (steam) temperature.Consider that intermediate pressure cylinder heat transfer influences, using can be by high pressure cylinder temperature drop to about on idle running cooling theory
150 DEG C, cylinder temperature drops to 154 DEG C and still has further downward trend during idle running is shut down in L401 overhaul.
In addition, the throttle (steam) temperature of intermediate pressure cylinder is set as 90 DEG C to 120 DEG C when separator is isolated, in
The throttle (steam) temperature of cylinder pressure is preferably arranged to 90 DEG C.
Reference table 2, this is by taking L3/4 machine as an example, when high intermediate pressure cylinder temperature data finds unit trip or makes lock, by middle pressure
Cylinder steam inlet condition influences, and intermediate pressure cylinder center housing temperature is higher, therefore halt turbines cylinder temperature also extends cooling time.Therefore, into one
Step ground, control steam-turbine unit beat the cylinder temperature of the intermediate pressure cylinder after lock within a short period of time i.e. lower than high pressure cylinder cylinder temperature so that steamer
Machine unit, which will beat the cooling rate after lock, to be accelerated.
High intermediate pressure cylinder temperature is shut down in 2 overhaul of table
Therefore, separator is isolated, reduces high intermediate pressure cylinder steam inlet condition, strengthens to cylinder cooling effect, from original
Reduction can be reached in reason and shut down cylinder temperature, shorten and shut down temperature fall time.Preferably, MSR second level reheater is isolated, so that in
The throttle (steam) temperature of cylinder pressure is set as 90 DEG C, in be pressed into stripping temperature comparison isolation before will decline 90 DEG C, further, pressed because beating in after lock
Cylinder temperature, which will be less than high pressure cylinder reviewing knowledge already acquired steam turbine, which will beat the cooling rate after lock, to accelerate.
Specifically, referring to Fig. 1 and Fig. 2, separator isolation or when operation, high intermediate pressure cylinder is into steam flow amount, temperature
With power of the assembling unit homologous thread, it is seen that intermediate pressure cylinder throttle (steam) temperature will be effectively reduced in separator isolation.Refinement ground, Fig. 1
Middle reactor steam flow when 1/2 grade of separator is put into operation, 1/2 grade of separator high pressure cylinder when putting into operation into
Steam flow amount, separator only 2 grades of steam flows of reactor when putting into operation, separators only 2 grades of high pressures when putting into operation
Reactor steam flow and 1/2 grade of separator isolation when cylinder is into 1/2 grade of steam flow amount, separator isolation
When high pressure cylinder compared into steam flow amount.It is to be appreciated that steam flow shown in figure can also be expressed as into steam flow amount.
Refinement ground, high pressure cylinder throttle (steam) temperature when 1/2 grade of separator being put into operation in Fig. 2,1/2 grade of separator put into operation
When intermediate pressure cylinder throttle (steam) temperature, separator only 2 grades of throttle (steam) temperatures of high pressure cylinder when putting into operation, only 2 grades of separator
High pressure cylinder throttle (steam) temperature and steam-water separation reheating when 1/2 grade of intermediate pressure cylinder throttle (steam) temperature, separator isolation when putting into operation
Intermediate pressure cylinder throttle (steam) temperature is compared when 1/2 grade of isolation of device.
In addition, after completing the step of separator is isolated, then separator is equipped with hydrophobic
Case is converted into lash-up drain mode.Further, separator is set as two column, and the separator of two column is logical
The drain tank for crossing setting carries out hydrophobic isolation, and the drain tank of the separator of two column goes to lash-up drain mode.
In addition, high pressure cylinder is connected by the side of more blow-off lines and separator, separator
The other side connect again by more Medium Pressure Steam Pipelines with intermediate pressure cylinder.Further, steam-turbine unit further includes Liang Tai in
Cylinder pressure is symmetrical and relative to the low pressure (LP) cylinder that intermediate pressure cylinder shunt is arranged, and intermediate pressure cylinder is connected by pressure blow-off line in two and low pressure (LP) cylinder
It connects.Specifically, the present embodiment is by taking L3/4 machine as an example, come the main steam of autothermal reactor evaporator by four main steam lines into
After entering high pressure cylinder acting, four high cylinder blow-off line is flowed through into two separators and carries out dehumidifying reheating, reheating is steamed
Vapour enters intermediate pressure cylinder by four Medium Pressure Steam Pipelines, finally continues to do by pressing blow-off line to enter two low pressure (LP) cylinders in two
Function.
Further, in the step of separator connected with high pressure cylinder, low pressure (LP) cylinder is isolated, simultaneously
The upper lower half cylinder wall temperature for monitoring high pressure cylinder and intermediate pressure cylinder is poor, so convenient for high pressure cylinder and intermediate pressure cylinder into steam flow amount and into vapour
Temperature is controlled.
In addition, it should be noted that, the maintenance of L305 overhaul conventional island main steam turbine is critical path, is stopped to shorten L305 overhaul
High intermediate pressure cylinder cylinder temperature is cooled to the critical path time of stoppage in transit master vehicle (allowing to stop transport lower than 150 degree) after machine.L305 overhaul stops
Idle running platform stop+MSR second level isolation method is used to carry out the cooling practice of cylinder temperature during machine.L305 overhaul is beaten after lock only
18 hours cylinder temperature are to be down to 150 degree (cylinder temperature that master vehicle allows to stop transport), and 42 hours ability natural coolings after lock are beaten in L301 overhaul
To 150 degree, L305 overhaul sophisticated practice works well, and saves cylinder temperature cooling critical path time about more than 20 hours.Compare L305/
Cylinder temperature cooling time is shut down in 404/306 overhaul, compared with L301/401 overhaul, effectively saves shutdown cylinder temperature and is cooled to master vehicle
Critical path time about 20 hours for allowing to stop transport.It should be noted that those skilled in the art, in the present embodiment before
