This 4.5MW generator package integrates a robust 3000r/min steam turbine with a high-voltage turbine alternator to deliver reliable waste heat power generation across a wide range of industrial applications. Engineered to maximize energy recovery, the Insun 4.5MW Steam Turbine Generator 10.5kV 3000r/min Waste Heat Power Generation Turbine Generator Set is optimized for continuous operation, delivering stable high-voltage turbine output while minimizing operational costs

Key Features and Design Highlights

The Insun 4.5MW Steam Turbine Generator 10.5kV 3000r/min Waste Heat Power Generation Turbine Generator Set features a compact footprint combined with modular construction for simplified installation. The 3000r/min steam turbine core is specifically designed for waste heat power generation applications, enabling efficient conversion of low- to medium-pressure steam into mechanical energy. This mechanical energy is directly coupled to a 4.5MW generator engineered as a high-voltage turbine alternator with a rated 10.5kV output, providing plant-level compatibility for grid interconnection and onsite power distribution

The aerodynamic and thermodynamic profiles of the 3000r/min steam turbine are optimized to achieve high isentropic efficiency across variable load conditions typical of waste heat power generation. The robust rotor design and precision balancing ensure long service life and reduced vibration, even under fluctuating inlet steam conditions common in industrial settings. The 4.5MW generator is tailored to operate as a high-voltage turbine unit, delivering stable 10.5kV output suitable for medium-voltage switchgear and local distribution networks

Applications and Use Cases

The Insun 4.5MW Steam Turbine Generator 10.5kV 3000r/min Waste Heat Power Generation Turbine Generator Set is ideal for industries that generate significant quantities of process waste heat, such as cement plants, steel mills, chemical manufacturing, petrochemical refineries, and waste-to-energy facilities. In these environments, the 3000r/min steam turbine is capable of converting available steam from waste heat recovery boilers into electricity via the 4.5MW generator, reducing purchased energy and improving overall plant efficiency. The high-voltage turbine capability simplifies integration into existing power systems, enabling direct export to onsite distribution networks or the public grid

In cogeneration and combined heat and power (CHP) installations, the unit enhances overall energy utilization by producing electricity with the 3000r/min steam turbine while enabling residual thermal integration for process heating. The waste heat power generation focus of the Insun package makes it particularly effective in retrofit projects where space constraints and compatibility with existing steam systems are key considerations
