Westinghouse, 501B, Gas Turbine, 73MW, 60 Hz, Dual-Fuel

Westinghouse, 501B, Gas Turbine, 73MW, 60 Hz, Dual-Fuel

Description

  1. Overview
    1. Two identical Westinghouse 501B (W-501-B) dual-fuel gas turbines, 73 MW each, 60 Hz
    2. Optional: two heat recovery steam turbine generators (HRSG/STG) at 100 MW each, available as separate lots
    3. Standard combined-cycle layout for this frame is 2×GT + 1×HRSG → 1×~100 MW STG (“2-on-1”) for ≈260 MW block rating
  2. Specifications Per Gas Turbine
    1. Make/model: Westinghouse W-501-B (501B family)
    2. Rated output (ISO, indicative): ~73 to 80 MW (site-dependent)
    3. Speed/frequency: 3,600 rpm / 60 Hz
    4. Fuel system: dual fuel – natural gas and distillate (diesel no. 2)
    5. Shaft: single-shaft generator drive
    6. Control system: Westinghouse controls
    7. Configuration: heavy-duty frame GT (Econopac-style enclosure)
    8. Hydrogen-cooled gas turbine generators of Pace 520 combined cycle
    9. Voltage: 13,800 V
    10. Rated output: 73,000 kW (73 MW)
    11. Hours since rebuild: 250 hours
  3. Performance Data
    1. Heat rate (simple-cycle): ~10,000 to 11,000 Btu/kWh (site-dependent)
    2. Heat rate (combined-cycle): ~8,100 to 8,500 Btu/kWh (LHV)
    3. Efficiency (simple-cycle): ~32 to 34%
    4. Efficiency (combined-cycle): ~40 to 42%
    5. Exhaust temperature: ~1,050 to 1,100°F (~565 to 590°C)
    6. Exhaust flow: ~1.5 to 1.7 million lb/hr (680 to 770 kg/s)
  4. Included Equipment
    1. Each unit comes with the turbine enclosure, inlet/exhaust ducting, switchgear/MCCs, and auxiliary systems
    2. Optional HRSGs and 100 MW steam turbine generators are also available
    3. Price includes complete pair of gas turbines, auxiliaries, completely disassembled and loaded on your truck
    4. Removal, crating, loadout price included
  5. Location and Availability
    1. Two identical W501B gas turbines available
    2. Two × ~100 MW steam turbine generators (HRSG) available
    3. All units can be sold individually or as a package
    4. Disclosure: all ratings are typical for W501B and subject to buyer verification against on-site nameplates, instruction book 1810-C453, and performance test data
    5. Ambient/site conditions materially affect output and heat rate
    6. 100% buyer responsibility; we can introduce you to expert resources who have experience in properly disassembling and transporting these turbines and all types of plant equipment worldwide
  6. Typical Applications
    1. Data centers
    2. Power plants
    3. Utility peaking / mid-merit
    4. Combined-cycle or cogeneration with HRSG / STG
  7. Additional Notes
    1. 73 MW = 73,000 kW ≈ 97,895 hp (per unit)
    2. Two GTs simple-cycle: ~146 MW total
    3. One 2×1 CC block (2 GT + 1 ST): ≈260 MW nominal
    4. Rated output of a Westinghouse 501B gas turbine: each 501B unit produces approximately 73–80 MW in simple-cycle mode at ISO conditions (59°F, sea level, 60% RH)
    5. Total plant output if combined with HRSG steam turbines: in a 2×1 combined-cycle block (2 GT + 1 HRSG/STG), total gross output is about 260 MW
    6. Efficiency can be expected from a W501B in combined-cycle operation: net plant efficiency is typically around 40–42% (≈8,100–8,500 Btu/kWh, LHV), depending on duct firing and site conditions
    7. Turbines suitable for peaking duty or baseload operation: the W501B is flexible; it can run as a peaker in simple-cycle mode or operate in combined-cycle for baseload/cogeneration
    8. Control system can be upgraded: many 501B units have been retrofitted from original Westinghouse controls to Siemens TXP or Emerson Ovation systems for modern reliability and compliance
    9. Fuels the W501B can burn: dual-fuel configuration – typically natural gas as primary and distillate (diesel) as secondary
    10. Parts and service still available for the W501B platform: Siemens Energy (successor to Westinghouse) and multiple aftermarket providers support 501B parts, upgrades, and field services worldwide
    11. Industries use the Westinghouse 501B: utilities, independent power producers (IPPs), cogeneration/industrial plants, and grid stability projects worldwide
    12. Can be relocated and re-installed: with proper dismantling, transport, and reassembly, W501Bs are commonly relocated; buyers should factor in logistics, rigging, and re-certification costs
