In addition, as shown in Figure 4, in guidance panel 60A, be provided with the emergency stop switch 63e of the running emergent stopping for making all Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10 ~ 50.If pressing emergency stop switch 63e, then the emergent stopping contact 60c of remote operation plate 60 connects, the running emergent stopping of all Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10 ~ 50.Wherein, although be only provided with an emergency stop switch 63e, emergency stop switch corresponding with each Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10 ~ 50 respectively also can be set.In addition, in Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10, storage battery 17 can be installed, and using the power supply of this storage battery 17 as remote operation plate 60.
Here, in the engine electric power generating system 1 of present embodiment, 1 Blast Furnace Top Gas Recovery Turbine Unit (TRT) among 5 Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10 ~ 50 becomes Blast Furnace Top Gas Recovery Turbine Unit (TRT) for subsequent use, and when Blast Furnace Top Gas Recovery Turbine Unit (TRT) for subsequent use stops, can being provided in the maximum load electric power that job site K1 ~ K5 envisions.That is, maximum load electric power when knowing that the power-jdriven gear 70 of each job site K1 ~ K5 operates in advance is below 1200kW.Therefore, because if all 4 Blast Furnace Top Gas Recovery Turbine Unit (TRT) all generate electricity with load factor 100%, the electric power of 1200kW can be supplied, so 1 Blast Furnace Top Gas Recovery Turbine Unit (TRT) made it not operate as Blast Furnace Top Gas Recovery Turbine Unit (TRT) for subsequent use.Like this, among 5 Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10 ~ 50, make 4 Blast Furnace Top Gas Recovery Turbine Unit (TRT) runnings, always make 1 Blast Furnace Top Gas Recovery Turbine Unit (TRT) for subsequent use stop on one side, then can carry out fuel supplement and maintenance relative to Blast Furnace Top Gas Recovery Turbine Unit (TRT) for subsequent use.
Such as, during certain section, Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10 made it to stop as Blast Furnace Top Gas Recovery Turbine Unit (TRT) for subsequent use and safeguards, and making other the parallel running of Blast Furnace Top Gas Recovery Turbine Unit (TRT) 20 ~ 50.In addition, during other, Blast Furnace Top Gas Recovery Turbine Unit (TRT) 20 made it to stop as Blast Furnace Top Gas Recovery Turbine Unit (TRT) for subsequent use and safeguards, and making other the parallel running of Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10,30 ~ 50.Like this, Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10 ~ 50 is made to stop successively, can the time safeguards easily in maintenance person.Further, among Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10 ~ 50 during certain Blast Furnace Top Gas Recovery Turbine Unit (TRT) fault, can supplement by Blast Furnace Top Gas Recovery Turbine Unit (TRT) for subsequent use.That is, do not need correspondingly with multiple Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10 ~ 50 to arrange Blast Furnace Top Gas Recovery Turbine Unit (TRT) for subsequent use respectively, for subsequent use of 5 Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10 ~ 50 entirety can be used as with 1 Blast Furnace Top Gas Recovery Turbine Unit (TRT) for subsequent use.Like this, the high engine electric power generating system of reliability 1 can be formed at an easy rate.Wherein, following, for ease of understanding situation, be described using the situation that Blast Furnace Top Gas Recovery Turbine Unit (TRT) 50 is made it to stop as Blast Furnace Top Gas Recovery Turbine Unit (TRT) for subsequent use.
Next, will 4 Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10 ~ 40 unit number control runnings be made or force the situation of running to be described as an example.First, in order to specify Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10 for leading machine, as shown in Figure 4, diverter switch 63c being switched to " manually ", and only the selector switch 63d corresponding with Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10 being switched to "ON".Then, the automatic operating switches 63a corresponding with Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10 ~ 40 is switched to "ON", and the pressure operating switches 63b corresponding with Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10 ~ 40 is switched to "Off".
Thus, the electric power generated electricity as the Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10 of leading machine is supplied to the power-jdriven gear 70 of each job site K1 ~ K5.After this, if the load electric of each job site K1 ~ K5 entirety is (following, be called " overall load electric power ") rise, the load factor of operating Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10 is more than the 1st rising fiducial value, then starting sequence is that the Blast Furnace Top Gas Recovery Turbine Unit (TRT) 20 of the 2nd starts run-in synchronism.In the run-in synchronism of Blast Furnace Top Gas Recovery Turbine Unit (TRT) 20, if the voltage of the voltage of Blast Furnace Top Gas Recovery Turbine Unit (TRT) 20, frequency, phase place and bus L1, frequency, phase place are consistent, then circuit breaker 24 (with reference to Fig. 3) is closed.Like this, if the run-in synchronism of Blast Furnace Top Gas Recovery Turbine Unit (TRT) 20 completes, then the electric power that Blast Furnace Top Gas Recovery Turbine Unit (TRT) 20 generates electricity is supplied to the power-jdriven gear 70 of each job site K1 ~ K5 via bus L1.
After this, similarly, if overall load electric power rises, the load factor of operating Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10,20 is more than the 2nd rising fiducial value, then starting sequence is that the Blast Furnace Top Gas Recovery Turbine Unit (TRT) 30 of the 3rd starts run-in synchronism, and the electric power that Blast Furnace Top Gas Recovery Turbine Unit (TRT) 30 generates electricity also can be supplied to power-jdriven gear 70.Then, if the load factor of operating Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10,20,30 is more than the 3rd rising fiducial value, then starting sequence is that the Blast Furnace Top Gas Recovery Turbine Unit (TRT) 40 of the 4th starts run-in synchronism, and the electric power that Blast Furnace Top Gas Recovery Turbine Unit (TRT) 40 generates electricity also can be supplied to power-jdriven gear 70.
On the other hand, if overall load electric power reduces, the load factor of operating Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10,20,30,40 is lower than the 1st decline fiducial value, then in starting sequence Blast Furnace Top Gas Recovery Turbine Unit (TRT) 40 at the latest, circuit breaker 44 (with reference to Fig. 3) is opened, and the electric power that Blast Furnace Top Gas Recovery Turbine Unit (TRT) 40 generates electricity becomes and can not be supplied to power-jdriven gear 70.At this moment, Blast Furnace Top Gas Recovery Turbine Unit (TRT) 40 becomes holding state and stops.After this, similarly, if overall load electric power reduces, the load factor of operating Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10,20,30 is lower than the 2nd decline fiducial value, then the electric power that the Blast Furnace Top Gas Recovery Turbine Unit (TRT) 30 that starting sequence the 2nd is slow generates electricity becomes and can not be supplied to power-jdriven gear 70.Then, if the load factor of operating Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10,20 is lower than the 3rd decline fiducial value, then the electric power that the Blast Furnace Top Gas Recovery Turbine Unit (TRT) 20 that starting sequence the 3rd is slow generates electricity becomes and can not be supplied to power-jdriven gear 70.
Like this, in unit number control running, because make the operating number of Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10 ~ 40 change according to the variation of overall load electric power, even so the little situation of overall load electric power, also can prevent that Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10 ~ 40 is superfluous to operate.Thereby, it is possible to minimizing fuel consumption, thus fuel cost can be suppressed.On the other hand, when carrying out pressure running, the pressure operating switches 63b corresponding with Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10 ~ 40 is switched to "ON".Thereby, it is possible to make the Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10 ~ 40 in all runnings generate electricity, the power-jdriven gear 70 to each job site K1 ~ K5 supplies electric power.Like this, in pressure running, because all Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10 ~ 40 in running can generate electricity, so can tackle the rising rapidly of overall load electric power at once.
At each job site K1 ~ K5, because almost the same time builds each apartment, and the number of units of the power-jdriven gear 70 used is also more, so the variation of overall load electric power is very large.But, as described above when carrying out the number of units of the Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10 ~ 40 generated electricity by unit number control running increase, to run-in synchronism completes, need the stipulated time.Therefore, if overall load electric power rises rapidly in the stipulated time till run-in synchronism completes, then likely exceed the electric power that the Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10 ~ 40 in running can supply.On the other hand, if carry out pressure running in advance, the rising rapidly of overall load electric power can be tackled, but force running if continue, then there is the problem that can become superfluous running when the variation of overall load electric power slows down.
Further, in existing engine electric power generating system, in unit number control running, the Blast Furnace Top Gas Recovery Turbine Unit (TRT) (leading machine) that generates electricity is carried out at first and order that Blast Furnace Top Gas Recovery Turbine Unit (TRT) is started is fixing.Therefore, if leading machine is set to Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10 to carry out unit number control running by hypothesis, then from construction period of about 1 year ~ 2 years on the whole, the duration of runs of Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10 becomes very many.That is, the inequality of the duration of runs of each Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10 ~ 50 becomes very large.Like this, also exist and be difficult to predict and carry out each fuel supplement of Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10 ~ 50 and the time of maintenance, and maintainable bad problem.
Therefore, in the engine electric power generating system 1 of present embodiment, in order to solve the problem, form as described below.As shown in Figure 4, in the guidance panel 60A of remote operation plate 60, be provided with the time input part 64 that can input and carry out the pressure duration of runs forcing running.In time input part 64, using among 1 day, the time of time and the end pressure running operated is forced to input the duration of runs as pressure by staff.Wherein, force the duration of runs among 1 day beyond time be configured to unit number control running time.Like this, auto-changeover control portion 62 based on the pressure duration of runs of input, can switch and force switching on and off of running contact 60b and unit number control running contact 60a, automatically switches and forces running and unit number control running.
Here, Fig. 6 is the figure of the variation representing overall load electric power among 1 day.The overall load electric power imagining each job site K1 ~ K5 in advance changes as shown in Figure 6.That is, due to from as during 8 o'clock of cut-in time were to 9 o'clock, more power-jdriven gear 70 entry into service, so overall load electric power rises rapidly.During this period, if hypothesis carries out unit number control running, then overall load electric power likely exceedes the electric power that the Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10 ~ 40 in running can supply, so need to carry out pressure running.
Then, during from 9 to lunch break 12, the variation of overall load electric power is smaller.During this period, if hypothesis carries out pressure running, then the load factor of each Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10 ~ 40 is lower likely becomes superfluous running, so carry out unit number control running better.In addition, due to during the lunch break of 12 o'clock to 13 o'clock, more power-jdriven gear 70 stops, so overall load electric power reduces rapidly, but by this moment also carrying out unit number control running, can suppress fuel cost.
Then, during terminate from lunch break 13 o'clock to 14 o'clock, more power-jdriven gear 70 entry into service, so overall load electric power rises rapidly.During this period, need to carry out pressure running.Finally, from 14 to as before 17 of the power cut-off time, the variation of overall load electric power is smaller, so carry out unit number control running better.Then, if reach the power cut-off time, then more power-jdriven gear 70 stops, so overall load electric power reduces rapidly.By at this moment also carrying out unit number control running, fuel cost can be suppressed.
Like this, in the engine electric power generating system 1 of the 1st execution mode, staff pre-enters time input part 64 to guidance panel 60A using from during 8 o'clock to 9 o'clock and from during 13 o'clock to 14 o'clock as forcing the duration of runs.Wherein, on the day off of not carrying out constructing, when distinguishing that the variation of overall load electric power is less in 1 day, staff does not input and forces the duration of runs, carries out unit number control and operate in 1 day.
In addition, in the time input part 64 of present embodiment, be configured to can by staff's input for switching the switching time of leading machine in unit number control running.Auto-changeover control portion 62 is configured to the switching time by inputting at time input part 64, among the Blast Furnace Top Gas Recovery Turbine Unit (TRT) running, switch leading machine successively.Such as, as described above when in unit number control running, leading machine is Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10, if through switching time, then leading machine is set as Blast Furnace Top Gas Recovery Turbine Unit (TRT) 20 by auto-changeover control portion 62, the Blast Furnace Top Gas Recovery Turbine Unit (TRT) of starting sequence the 2nd is set as Blast Furnace Top Gas Recovery Turbine Unit (TRT) 30, the Blast Furnace Top Gas Recovery Turbine Unit (TRT) of starting sequence the 3rd is set as Blast Furnace Top Gas Recovery Turbine Unit (TRT) 40, the Blast Furnace Top Gas Recovery Turbine Unit (TRT) of starting sequence the 4th is set as yes the Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10 of leading machine last time.
After this, if through switching time, then leading machine is set as Blast Furnace Top Gas Recovery Turbine Unit (TRT) 30 by auto-changeover control portion 62, the Blast Furnace Top Gas Recovery Turbine Unit (TRT) of starting sequence the 2nd is set as Blast Furnace Top Gas Recovery Turbine Unit (TRT) 40, the Blast Furnace Top Gas Recovery Turbine Unit (TRT) of starting sequence the 3rd is set as Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10, the Blast Furnace Top Gas Recovery Turbine Unit (TRT) of starting sequence the 4th is set as yes the Blast Furnace Top Gas Recovery Turbine Unit (TRT) 20 of leading machine last time.Later similarly by switching leading machine switching time.But auto-changeover control portion 62 only when diverter switch 63c is switched to " automatically ", switches leading machine successively.
The action effect of the 1st execution mode is described.
According to the engine electric power generating system 1 of the 1st execution mode, if reach 8 points, then auto-changeover control portion 62 automatically switches to and carries out pressure running, after lasting pressure running is till 9 o'clock, automatically switches to unit number control running.After this, if reach 13 points, then auto-changeover control portion 62 automatically switches to and carries out pressure running, after lasting pressure running is till 14 o'clock, automatically switches to unit number control running.
Like this, in the time period that overall load electric power rises rapidly, all Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10 ~ 40 in running can generate electricity at once, so can tackle the rising rapidly of overall load electric power.As a result, can reliably prevent each Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10 ~ 40 from transshipping thus the state of affairs had a power failure.On the other hand, in the time period that overall load electric power slowly changes, increase and decrease the number of units of the Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10 ~ 40 of generating according to load factor.Therefore, even the situation that the load factor of Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10 ~ 40 is less, also can prevent more Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10 ~ 40 from continuing the surplus running of generating, can fuel cost be suppressed.Further, because do not carry out pressure running under the situation that the load factor of Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10 ~ 40 is little, so can prevent each Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10 ~ 40 from operating with underload.Therefore, it is possible to suppress to produce unburned gas from the engine of each Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10 ~ 40, thus be difficult to break down.
In addition, according to the engine electric power generating system 1 of the 1st execution mode, staff such as will input to the time input part 64 of guidance panel 60A among 1 day morning 0 as switching time.Thus, if reach point in morning 0 every day, then automatically switch leading machine among Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10 ~ 40.Therefore, from the construction periods of about 1 year ~ 2 years on the whole, in Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10 ~ 40, the duration of runs of each Blast Furnace Top Gas Recovery Turbine Unit (TRT) is averaged.As a result, each fuel supplement of Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10 ~ 40 and the inequality of the time of maintenance can be eliminated, can maintainability be improved.
About the situation of engine electric power generating system 1 using existing method and the 1st execution mode, fuel cost is compared and is described.In the conventional method, in order to reliably prevent the state of affairs had a power failure relative to rising rapidly of overall load electric power, 4 Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10 ~ 40 are set to the state that 1 day (8 hours) always can force to operate.At this moment, if 4 Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10 ~ 40 generated electricity 4 hours among 1 day, load factor is 25%.When in 1 Blast Furnace Top Gas Recovery Turbine Unit (TRT) load factor be 25% to generate electricity time, fuel consumption is 29.8 liters per hour.Therefore, in the conventional method, within every 1 day, the fuel of 29.8 × 4 hours × 4=476.8 liters is consumed.
On the other hand, in engine electric power generating system 1,4 Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10 ~ 40 entirety carry out pressure running and unit number control running efficiently, and can assume with 1 power station running.If generating 4 hours among 1 power station 1 day, load factor is 100%.When in 1 power station load factor be 100% to generate electricity time, fuel consumption is 95.2 liters per hour.Therefore, in engine electric power generating system 1, within every 1 day, consume the fuel of 95.2 × 4 hours × 1=380.8 liters.Like this, in existing method and engine electric power generating system 1, within every 1 day, produce the difference of the fuel consumption of 96 liters.If suppose 1 liter of fuel 100 yen, then within every 1 day, produce the difference of 9600 yen.As a result, every 1 year of construction period, can save the fuel cost of 9600 yen × 365 days=3504000 yen.
" the 2nd execution mode "
Next, the 2nd execution mode is described.In the 2nd execution mode, be described centered by the part different from the 1st execution mode, omit the explanation about identical part.Fig. 7 is the front view of the guidance panel 60Y of the remote operation plate 60X representing the 2nd execution mode.As shown in Figure 7, in guidance panel 60Y, be provided with the automatic mode switch 65 switched on and off can selecting automatic mode.
Even if automatic mode refers to that staff does not force the pressure of running to input to time input part 64 duration of runs by carrying out, also automatically switch in every day of construction period the pattern of unit number control running and pressure running in auto-changeover control portion 62.If automatic mode switch 65 is selected as " connection ", then auto-changeover control portion 62 performs automatic mode.Auto-changeover control portion 62, in order to perform automatic mode, stores the time period of carrying out unit number control running and the alteration mode VP carrying out the time period forcing running (with reference to Fig. 9).Below, alteration mode VP is described.
Alteration mode VP is variation based on the overall load electric power in every day of construction period and by the multiple patterns determined.Here, in construction field, according to construction calendar or Construction Condition etc. in the past, the variation of the overall load electric power in the every day can inferring construction period to a certain degree.Fig. 8 is the figure of the variation of the maximum of the overall load electric power schematically showing job site K1 ~ K5.Such as when building apartment with the construction period of 1 year, as shown in Figure 8, carrying out foundation construction with 1 month, carrying out crane job and concreting with 8 months after this, carrying out upholstery construction with last 3 months.And relative with needing very large electric power in crane job, in foundation construction, electric power is less.Like this, as shown in Figure 8, the maximum change of overall load electric power can be inferred, and as shown in Figure 9, determine alteration mode VP.
In fig .9, as the alteration mode VP that auto-changeover control portion 62 stores, shown with A pattern and B-mode and C mode.Representing in A pattern in the every day when carrying out foundation construction, carrying out the time period of unit number control running and carrying out forcing the time period of running.Known in foundation construction, as shown in Figure 8, the maximum of overall load electric power is smaller, and as shown in Figure 9, the time period that overall load electric power rises rapidly is from during 8 o'clock to 8 thirty and from during 13 o'clock to 13 thirty, is the shorter time period.Therefore, auto-changeover control portion 62 is in every day of 1 month of foundation construction, store from the time period during 8 o'clock to 8 thirty and during 13 o'clock to 13 thirty as the time period of carrying out pressure running, the time period beyond this was stored as the time period of carrying out unit number control running.
B-mode represents in the every day when carrying out crane job and concreting, carries out the time period of unit number control running and carries out forcing the time period of running.Known in crane job and concreting, as shown in Figure 8, the maximum of overall load electric power very large, as shown in Figure 9, the time period that overall load electric power rises rapidly is from during 8 o'clock to 10 o'clock and from during 13 o'clock to 15 o'clock, is the longer time period.Therefore, auto-changeover control portion 62 is in the every day of 8 months of carrying out crane job and concreting, using from during 8 o'clock to 10 o'clock and from during 13 o'clock to 15 o'clock as carrying out forcing the time period of running to store, the time period beyond this was stored as the time period of carrying out unit number control running.
C mode represented in the every day when carrying out upholstery construction, carried out the time period of unit number control running and carried out forcing the time period of running.Known in upholstery construction, as shown in Figure 8, the maximum of overall load electric power is in the centre of above-mentioned two kinds of condition of construction, and as shown in Figure 9, the time period that overall load electric power rises rapidly is from during 8 o'clock to 9 o'clock and from during 13 o'clock to 14 o'clock.Therefore, auto-changeover control portion 62 is carrying out every day of upholstery construction, using from during 8 o'clock to 9 o'clock and from during 13 o'clock to 14 o'clock as carrying out forcing the time period of running to store, the time period beyond this was stored as the time period of carrying out unit number control running.Wherein, for alteration mode VP, use the outside input mediums such as computer, be previously stored before construction starts to auto-changeover control portion 62.
The action effect of the 2nd execution mode is described.
Based on construction calendar or Construction Condition in the past, when determining the alteration mode VP shown in Fig. 9 best, this alteration mode VP pre-enters to auto-changeover control portion 62 and stores by staff.Thus, if select automatic mode switch 65 be " connections ", then in every day of construction period, can operate in automatically switch unit number control running and pressure of Best Times.As a result, the supervision burden of remote operation plate 60X can be alleviated.
Above, each execution mode of engine electric power generating system involved in the present invention is illustrated, but the present invention is not limited to these execution modes, can various change be carried out in the scope not departing from this purport.
Such as, in each execution mode, engine electric power generating system 1 is configured to possess 5 Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10 ~ 50, but the number of units of Blast Furnace Top Gas Recovery Turbine Unit (TRT) also can be 6, can appropriate change.In addition, the quantity of job site K1 ~ K5 is not limited to 5, can appropriate change, and the kind of power-jdriven gear is also not limited to each power-jdriven gear 71 ~ 75.
In addition, in the 1st execution mode, by forcing the duration of runs to time input part 64 input, auto-changeover control portion 62 carries out pressure running for pressure the duration of runs, unit number control running is carried out for the time forced beyond the duration of runs, but also can by inputting unit number control duration of runs to time input part 64, auto-changeover control portion 62 carries out unit number control running for unit number control the duration of runs, carries out pressures operate for the time beyond unit number control duration of runs.
In addition, in the 1st execution mode, Blast Furnace Top Gas Recovery Turbine Unit (TRT) for subsequent use is 1, but also can be 2, and the number of units of Blast Furnace Top Gas Recovery Turbine Unit (TRT) for subsequent use can appropriate change.
In addition, in the 2nd execution mode, the alteration mode VP of Fig. 9 just illustratively example of display, according to the variation of the overall load electric power in every day of construction period, alteration mode also can be more than 4 kinds, can appropriate change.
