Taiwan widely applies Organic Rankine Cycle (ORC) technology system in geothermal power generation, waste heat recovery, cold energy recovery, and renewable energy utilization. By enhancing energy efficiency, reducing electricity costs, and cutting carbon emissions, ORC has become a pivotal solution for sustainable energy. ORC systems use turbines or screw expanders to convert gas expansion into mechanical energy, driving generators with power capacities ranging from 10 kW to 2,000 kW, making them adaptable to diverse energy scenarios.

In this field, Nikkiso’s Radial Inflow Turbine stands out, optimized for high-efficiency power generation in small to medium-sized systems. With a capacity range of 5 MW to 25 MW, it supports flexible deployment through single or multiple units. Compared to traditional expanders, Nikkiso’s Radial Inflow Turbine offers the following distinct advantages:

1. High-Efficiency Design

• Variable Geometry Design: By dynamically adjusting the turbine’s geometric structure, optimal performance is maintained under varying operating conditions.
• Adjustable Inlet Guide Vanes: Effectively control airflow and angles to optimize energy utilization efficiency.

2. Superior Adaptability in Design

• Internal Dynamic Adjustment Mechanism: Enables flexible tuning of operating parameters to meet varying conditions, ensuring stable operation and high-efficiency power generation.
• Compatible with heat sources ranging from as low as 80°C to as high as 250°C (175°F to 500°F).
• Suited for a wide range of applications, from small-to-medium systems (5 MW) to large-scale systems (25 MW), supporting flexible configurations with single or multiple units.

3. Island Mode Operation

• The system operates independently without support from an external power grid, supplying power to specific loads.

4. Stability and Reliability

• The design features simplicity and efficiency, ensuring stable operation and low maintenance costs.
• It is particularly suited for handling working fluids with medium to high-pressure differentials, significantly enhancing power generation efficiency.

5. Broad Range of Applications
