A. ONCE THROUGH STEAM GENERATOR
ONCE THROUGH STEAM GENERATORS ALSO CALLED OTSG ARE SUPPLIED BY IST, CANADA. THESE ARE THE STEAM GENERATORS, WHICH GENERATE STEAM FOR POWER GENERATION IN STEAM TURBINE. THE HEAT IN THE EXHAUST GASES FROM GAS TURBINES IS TRANSFERRED TO FEED WATER TO GENERATE STEAM AT TWO PRESSURES, HP & LP. THE OTSG ARE DRUM LESS BOILERS HAVING TUBE BUNDLES WHERE STEAM IS GENERATED. FEED WATER IS SUPPLIED TO OTSG THROUGH FEED WATER PUMPS AFTER TREATING THE WATER IN CONDENSATE POLISHING UNIT. SUPPLING DM WATER TO CONDENSER HOT WELL FULFILS THE ADDITIONAL MAKEUP REQUIREMENT. THE EXHAUST GASES AFTER GIVING THEIR HEAT TO FEED WATER ARE LET OFF TO ATMOSPHERE THROUGH STACK. THE OTSG HAS A DRY RUNNING CAPABILITY UP TO 560°C.

C. CHILLERS
CHILLERS ARE USED TO COOL GAS TURBINE INTAKE AIR AND ENHANCING THE OUTPUT OF EACH GAS TURBINE BY 7 TO 10 MW APPROXIMATELY. THE CHILLERS OPERATE ON VAPOUR COMPRESSION CYCLE. CHILLED WATER IS CIRCULATED THROUGH EVAPORATOR WHERE IT REJECTS HEAT TO REFRIGERANT HFC134A AND BECOME CHILLED. THIS CHILLED WATER AGAIN PICKS UP HEAT FROM GAS TURBINE INTAKE AIR-COOLING THEM. THE BOILED REFRIGERANT IS THAN COMPRESSOR. THE HEAT ADDED TO THE REFRIGERANT IN EVAPORATOR AND COMPRESSOR IS THAT REJECTED IN CONDENSER, COOLED BY SEA WATER. THE MOTOR IS HERMETICALLY SEALED. LUBE OIL AND MOTOR WINDINGS ARE COOLED BY REFRIGERANT. THEREFORE HEAT FROM A LOW TEMPERATURE SOURCE IS REJECTED TO HIGH TEMPERATURE SOURCE.

SPRINT SYSTEM
THE TERM “SPRINT” (SPRAY INTERCOOLING) IS A TECHNOLOGICAL ADVANCEMENT THAT HAS BEEN DEVELOPED BY GE INDUSTRIAL AERO DERIVATIVE GAS TURBINES (GE-IAD) TO ENHANCE THE OUTPUT PERFORMANCE OF THE LM6000 GAS TURBINE. THE ADDITION OF GE‟S PROPRIETARY SPRINT TECHNOLOGY INCREASES THE OUTPUT BY 9% AT ISO AND BY MORE THAN 20% ON 90° F (32°C) DAYS. THE EFFECTIVENESS OF THE SYSTEM BECOMES MORE PRONOUNCED AS AMBIENT TEMPERATURES RISE.
THE SPRINT SYSTEM BEGINS A MIST INJECTION PROCESS ONCE THE TURBINE REACHES FULL LOAD OPERATION; NO ENHANCEMENT BENEFITS ARE ACHIEVED AT PART LOAD FOR EITHER POWER AUGMENTATION OR DECREASED HEAT RATE.
THE SPRINT COOLING TECHNOLOGY LOWERS THE HIGH-PRESSURE COMPRESSOR (HPC) INLET TEMPERATURE (T2.5), WHICH IN TURN EFFECTIVELY LOWERS THE HPC COMPRESSOR DISCHARGE TEMPERATURE (T3).

BAROMETRIC PRESSURE 14.6% (101.4 KPA)

THE SYSTEM CONSISTS OF TWO MULTI-NOZZLE INTER STAGE MIST INJECTION SYSTEMS
1) THE LOW-PRESSURE COMPRESSOR (LPC) MIST INJECTION SYSTEM CONSISTS OF A SINGLE ROW OF 23 NOZZLES LOCATED IN THE INLET OF THE LPC.
2) THE HIGH-PRESSURE COMPRESSOR (HPC) MANIFOLD IS SPLIT INTO TWO (2) SEPARATE MANIFOLDS (INNER / OUTER) CONSISTING OF TWO ROWS OF 12 NOZZLES EACH FOR A COMBINED TOTAL OF 24 NOZZLES. THE HPC MANIFOLDS ARE LOCATED IN THE COMPRESSOR FRONT FRAME SUPPORT HOUSING BETWEEN THE LPC AND HPC.

ONLY ONE MANIFOLD WILL BE OPERATIONAL AT A GIVEN TIME. WHICH MANIFOLD IS ENERGIZED IS DEPENDENT ON THE INLET AIR TEMPERATURE. INLET AIR TEMPERATURES OF ≥ 48°F ENABLES THE LPC SOV VALVE TO BE OPENED WHEN THE SYSTEM IS ENABLED. WHEN TEMPERATURE DROP BELOW 48°F THE LPC MANIFOLD WILL BE DE-ENERGIZED AND HPC MANIFOLD ENERGIZED. IF THE TEMPERATURE CONTINUES TO DROP, AT 41°F BOTH HPC AND LPC WILL BE DE- ENERGIZED. AS TEMPERATURES INCREASE FROM BELOW 41°F THE HPC MANIFOLD WILL BE REENERGIZED AT 43°F INCREASING AND AT 50°F INCREASING THE LPC MANIFOLD WILL BE REENERGIZED AND HPC MANIFOLD DE-ENERGIZED.

AIR EXTRACTED FROM THE ENGINE 8TH STAGE HPC BLEED AIR EXTRACTION PORT IS UTILIZED TO ATOMIZE & PRESSURIZE THE SYSTEM BY USING THE SPRINT SPRAY INTER-COOLING SYSTEM, THE COMPRESSOR PRESSURE RATIO CAN BE INCREASED AND ADDITIONAL AIR CAN BE DIRECTED THROUGH THE COMPRESSOR TO INCREASE THE GAS TURBINE CHARACTERISTICS

DEMINERALISED WATER IS SUPPLIED TO THE SPRINT SYSTEM FROM DM PLANT. IT IS SUPPLIED AT A RATE OF 10-GPM MINIMUM TO 30 GPM MAXIMUM AND AT PRESSURES 0-65 PSIG. AFTER INTERFACE CONNECTION, IT FLOWS THROUGH A Y-TYPE STRAINER, A NORMALLY OPEN BALL VALVE TO A CENTRIFUGAL PUMP. THE CENTRIFUGAL PUMP IS DRIVEN BY MOTOR RATED AT 10 HP. AFTER THE PUMP, THE DEMINERALISED WATER PRESSURE IS MONITORED BY PRESSURE SWITCH LOW PSL-62227 WHICH ACTIVATES PRESSURE ALARM LOW PAL- 62227 IN THE EVENT THE WATER PRESSURE FALLS BELOW 75 PSIG. PRESSURE GAUGE PI-62229 SCALED 0-400 PSIG DISPLAYS PUMP DISCHARGE PRESSURE. THE DEMINERALISED WATER THEN FLOWS THROUGH A FLOW METER, SOLENOID ACTUATED BLOCK VALVE, AND ENTERS A DUPLEX FILTER THAT FILTERS THE WATER TO 20 MICRONS ABSOLUTE. PRESSURE DIFFERENTIAL SWITCH HIGH PDSH-62233 MONITORS THE DIFFERENTIAL PRESSURE ACROSS THE FILTERS AND ACTIVATES AN ALARM SHOULD THE DIFFERENTIAL PRESSURE INCREASE TO 10 PSID.
