The Training simulator is designed and manufactured as most modern system & trainee may have a good feeling for plant operation, as in the actual power plant, however, some unimportant part are excluded from our system, and so on, simulator is not exactly same as the actual plant construction. some samples of difference between the simulator system & actual one are as follows:
>> What Items are not Modeled (well) ? >> What Items are not Modeled (well) ? (2/4)(2/4)
@ Simulator @ Actual PlantFuel oil tanks are always ful-filled & supplied oil from tanks are warmed up by suction heaters or buttom heaters
Level of the tanks should checked before start the fuel oil pumps. It takes so long times to warm up the fuel oil supplied from the tanks. Such warm up work should be started about 2 or 3 hours before pump is start.
Burner operation is simulated only their logic system.
At the actual burner operation, periodic burner gun cleaning is necessary in order to get the good & reliable combustion. This routine maintenance could not be experienced by the simulator.
Circulating water system is simplified.
At the actual power plant, two sets of main C.W.P, aux. C.W.P & distiled recirculating pump are installed. The complete cooling is also simplified.
Demineralized water tank is always kept at normal water level
Demineralized water is necessary a big amount especially for cold start up because for fill-up the water to the dearator & boiler & also for the long period of the silica purge operation. Because of above mentioned reason, demineralized water tank should be kept at full before start the plant.
>> What Items are not Modeled (well) ? >> What Items are not Modeled (well) ? (3/4)(3/4)
@ Simulator @ Actual PlantFeed water heating system is simplified.
At the actual power plant, many numbers of the LP & HP feed water heaters are adopted & much complicate operation procedure is needed..
Local control systems are excluded So many numbers of local control systems are installed. Operator should check the condition of their operation before & during the start up priod.
Compressed air system is excluded. Three service air compressors & four instrument air compressors are installed. Operator should check the condition of their operation before & during the start up period.
Soot blower system is excluded Soot blowers should be operated by checking the draft loss in the boiler system.
>> What Items are not Modeled (well) ? >> What Items are not Modeled (well) ? (4/4)(4/4)
@ Simulator @ Actual PlantNitrogen sealing system is excluded
When long term shut-down is expected, boiler, high pressure feed water heaters & dearator should be reserved by pressurized nitrogen gas to prevent the infiltration of air into them.
Chemical dosing system is excluded.
PH value control & de-oxygen for the boiler feed water is made by injecting the hydrogen and/or ammonia hydrate into the feedwater. Dosing rate of these chemicals should be adjusted correspond to the feed water flow rate and also to the analitical value.
