What Is an Extraction/Condensing Steam Turbine?
An extraction/condensing steam turbine generates electricity while also allowing intermediate-pressure steam to be extracted for process applications before the remaining steam is condensed.
This design enables:
- Combined heat and power (CHP) operation
- Improved overall plant thermal efficiency
- Reduced fuel consumption per unit of output
- Flexible steam header pressure management
- Stable electrical output under variable steam loads
Extraction turbines are commonly installed in refineries, chemical plants, pulp & paper mills, district energy systems, and large manufacturing facilities.
What Is 6.6 kV Power Output Used For?
A 6.6 kV generator output is standard in medium-voltage industrial power systems. It is commonly used for:
- Plant-wide electrical distribution
- Large motor loads
- Process compressors and pumps
- Industrial production lines
- Grid interconnection via step-up transformers
Medium-voltage turbine generators are widely used in industrial captive power plants and cogeneration facilities across North America, Asia, and the Middle East.
Steam Conditions & Efficiency
With inlet steam at 455 PSI and 750°F, this turbine operates within typical industrial high-pressure steam parameters. The 50,000 PPH extraction at 133 PSI supports medium-pressure steam headers, while 2 PSI exhaust enables efficient condensation and energy recovery downstream.
This configuration is well suited for facilities operating boilers in the 90,000–150,000+ PPH range seeking balanced power and steam utilization.
Typical Industrial Applications
This 7.5 MW steam turbine generator is suitable for:
- Cogeneration (CHP) plants
- Oil & gas processing facilities
- Petrochemical operations
- Pulp & paper mills
- District heating systems
- Industrial manufacturing complexes
- Refinery steam and power systems
Industrial buyers globally often source surplus steam turbine generators for plant expansions, energy efficiency upgrades, or replacement of aging turbine systems.
Benefits of Purchasing a Used Steam Turbine Generator
Acquiring a surplus steam turbine generator can provide:
- Significant capital savings versus new OEM units
- Faster deployment timelines
- Reduced engineering lead time
- Proven operational design
- Reliable mid-range MW capacity for industrial power generation
For facilities requiring immediate 7.5 MW power generation with process steam extraction capability, this Shin Nippon Machinery turbine offers a practical and scalable solution.
