REFERENCE NUMBER: TT-7587 SIEMENS TG50D5/W701DS GAS TURBINE GENERATOR, 127.8 MW, YEAR 1995 1. SIEMENS WESTINGHOUSE TG50D5/W701DS 127.8 MW GAS TURBINE GENERATOR PACKAGES FOR SALE. THE TURBINE PACKAGES TOGETHER OFFER 255 MW READY TO SHIP EQUIPMENT. THIS TECHNOLOGY IS ONE OF THE MOST WIDESPREAD MIDDLE SIZE ENGINES (100-104 MW) FOR POWER GENERATION AND THE ONLY TURBINE OF ITS SIZE THAT CAN OPERATE ON HEAVY FUEL OIL (HFO). 2. THE UNITS ARE OFFERED WITH SOME OF THE REQUIRED BALANCE OF PLANT BY SEPARATE NEGOTIATION. 3. THESE UNITS WERE INSTALLED AND OPERATED IN A POWER STATION FROM 1996 UNTIL THE END OF 2004, WHEN THEY WERE DISMANTLED AS THE RESULT OF A PLANT UPGRADE. THE UNITS WERE PURCHASED AND UPGRADED BY THE BUYER TO 127.8 MW NOMINAL CAPACITY EACH. THEY ALSO FULLY REFURBISHED THE UNITS TO ZERO HOURS. THE TURBINES HAVE THE CAPABILITY OF BEING ABLE TO SWITCH BETWEEN NATURAL GAS AND LIQUID FUEL WHILE STILL OPERATING UNDER LOAD. WARRANTIES 1. THE UNITS HAVE BEEN CAREFULLY STORED SINCE THE TIME OF THE MAJOR OVERHAUL THE GAS TURBINE AND OF GENERATOR ASSEMBLIES INCLUDING STATOR AND ROTOR OVERHAULS WHICH WAS COMPLETED IN 2010. THE BUYER ALSO UPGRADED THE GAS TURBINE LONGITUDINAL SECTIONS TO 127.8 MW ISO CONDITION ACCORDING TO THE OEM TECHNICAL SPECIFICATION. 2. WARRANTIES AT A COST WILL BE AVAILABLE SUBJECT TO THEIR INSPECTION AND SOME MINOR SERVICING (SEAL REPLACEMENTS ETC) OF THE MACHINES WHICH HAVE BEEN STORED FOR IN EXCESS OF 10 YEARS 3. FULL OVERHAUL REPORTS ARE AVAILABLE. 4. IN-SERVICE YEAR 1995 5. EQUIVALENT HOURS 40,113 TO 49,064 6. IT SHOULD BE NOTED THAT BOTH UNITS WERE REFURBISHED TO ZERO HOURS FOR ROUTINE OVERHAUL PERIODS. ISO PERFORMANCE 1. NET ELECTRIC OUTPUT 127.8 MW 2. HEAT RATE OCGT 11,149 KJ/KWH 3. EFFICIENCY OCGT 32% 4. EFFICIENCY CCGT 52% EQUIPMENT LIST 1. EACH OF THE TWO (2) GAS TURBINE OPERATING ISLANDS COMPRISES: 2. GAS TURBINES W701DS: MODULE FOR OUTDOOR INSTALLATION AND SUITABLE FOR DISTILLATE, HFO AND NATURAL GAS OPERATIONS. 3. ABB 50 Hz SYNCHRONOUS GENERATOR: MODULE, HYDROGEN COOLING TYPE. BALANCE OF PLANT 1. AVAILABLE BY SEPARATE NEGOTIATION AND CONFIRMATION 2. ELECTRICAL PACKAGE 3. - GENERATOR CIRCUIT BREAKER; 4. - STARTING SYSTEM BOARD AND TRANSFORMER (1 PACKAGES FOR 2 POWER ISLANDS). 5. - STATIC FREQUENCY CONTROLLER 6. - BARRING GEAR MECHANICAL PACKAGE 1. - COMMON LUBE OIL SYSTEM FOR THE GAS TURBINE AND GENERATOR 2. - GAS FUEL SYSTEM SKID 3. - LIQUID FUEL SYSTEM SKID 4. - COOLING WATER SKID 5. - WATER INJECTION SKID 6. - LIQUID FUEL FORWARDING SKID 7. ROTOR JACKING OIL SYSTEM AND HYDROGEN OIL SYSTEM. BOP REQUIRED 1. MUCH OF THE NECESSARY BOP REQUIRED TO OPERATE THE GAS TURBINES HAS BEEN SCRAPPED AS UNSERVICEABLE OR BECAUSE OF STORAGE CONSTRAINTS. THIS INCLUDES MAJOR ITEMS SUCH AS: 2. AIR FILTERS 3. EXHAUST STACKS AND SILENCERS 4. CONTROLS AND INSTRUMENTATION 5. WATER AND AIR COOLERS 6. GSU AND AUXILIARY TRANSFORMERS 7. EQUIPMENT HOUSINGS, ACCESS LADDERS AND WALKWAYS, PIPE RACKS ETC GENERAL REMARKS FOR RELOCATION 1. NOX ABATEMENT. 2. A WATER DEMINERALISED SYSTEM FOR NOX ABATEMENT WILL BE REQUIRED IF THE COUNTRY OF DESTINATION HAS STRINGENT ANTI-POLLUTION RULES. IF THEY ARE LESS STRINGENT, IT IS POSSIBLE TO RUN THE UNITS WITHOUT WATER DEMINERALISATION SYSTEM BUT WITH A 250PPM NOX EMISSION. 3. WITH WATER INJECTION BENEFITS ARE (AT ISO CONDITIONS AND BASE LOAD): NATURAL GAS FUEL EMISSIONS BELOW 35 PPMV NOX CORRECTED TO 15% O2. O #2 DISTILLATE FUEL EMISSIONS BELOW 140 PPMV NOX CORRECTED TO 15% O2 MAINTENANCE PROGRAM 1. THE W701DS MAINTENANCE PROGRAM PROVIDES FOR FOUR TYPES OF INSPECTIONS DIFFERING IN SCOPE AND INTERVAL: 2. COMBUSTION SYSTEM INSPECTION (ISC) 1 WEEK, 6 MEN PER 8 HRS/DAY 3. REDUCED HOT PART INSPECTION (RPCR) 3 WEEKS, 6 MEN PER 8 HRS/DAY 4. HOT GAS PATH INSPECTION (RPC) 7 WEEKS, 6 MEN PER 8 HRS/DAY 5. GENERAL REVISION (RGTG) 11 WEEKS, 6 MEN PER 8 HRS/DAY 1. THE MAINTENANCE INTERVAL ON THE BASIS OF THE EQUIVALENT HOURS (EH) ARE: 2. ISC 8,000 EH 3. RPCR 16,000 EH 4. RPC 24,000 EH 1. DISMANTLING AND PACKING WAS PERFORMED BY THE OEM WITH MAXIMUM CARE AND ACCORDING TO ACCEPTED STANDARDS WHICH PRESERVE ALL THE EQUIPMENT, MACHINERY AND PARTS, AND WILL ALLOW THE REERECTION WORK IN THE NEW SITE OF DESTINATION WITHOUT ANY DISTURBANCE. THE DISMANTLING AND PACKING WORKS WERE PERFORMED IN THE FOLLOWING ORDER: 2. REMOVAL OF ANY KIND OF OILS, GREASE, CHEMICALS, WATER, ETC. CONTAINED IN THE EQUIPMENT AT THE START OF THE DISMANTLING WORKS. 3. DISCONNECTION OF JOINTS, GEARS, ETC. BETWEEN MACHINERY WITH MAXIMUM CARE IN ORDER TO AVOID DAMAGE BETWEEN THE PARTS. 4. DISCONNECTION OF ANCHOR BOLTS. 5. DISMANTLING OF EQUIPMENT AND MACHINERY 6. PROTECTIVE PACKING ARRANGEMENTS TO SECURE THE DISMANTLED COMPONENT FOR TRANSPORTATION AND STORAGE AND TO PRESERVE THEM FROM HUMIDITY. CONCLUSION 1. THE W701DS TECHNOLOGY IS DESIGNED FOR DUAL FUEL USE WITH CAPABILITY OF SWITCHING BETWEEN NATURAL GAS AND DISTILLATE /HFO WHILE STILL OPERATING UNDER LOAD. HFO IS OFTEN USED AS A BACKUP FUEL FOR PEAKING POWER PLANTS IN CASE THE SUPPLY OF NATURAL GAS IS NOT SUFFICIENT. IN OTHER CASES WHEN NATURAL GAS MAY BE THREATENED OR INTERRUPTED HFO IS USED AS THE SUBSTITUTE FUEL FOR POWER PLANTS. QUANTITY: 2
