On November 22, Harbin Turbine Co., Ltd. (a subsidiary of Harbin Electric Group, hereinafter referred to as “Harbin Turbine”) independently developed The world's first 660-megawatt dual-medium-pressure cylinder multi-stage combined heat and power turbine unit successfully achieved dual-unit commissioning at the State Power Investment Corporation Fuzhou Phase II Project. The unit operates smoothly with excellent performance metrics. As the first major demonstration project for the fifth batch of national energy sector equipment, the successful commissioning of this project marks another significant breakthrough in China's research, development, and application of high-parameter, large-capacity cogeneration equipment.

As a key project for Fujian Province to optimize its energy structure and advance the “dual carbon” goals, the Guoneng Fuzhou Phase II project had three core requirements clearly stated by the client at the outset:Maintain high-efficiency operation of the unit under 660MW pure condensing conditions; Meet multi-level, high-parameter, and adjustable steam extraction requirements; Achieve adjustable steam extraction to advance thermal-electric decoupling. Harbin Electric Turbine adheres to the philosophy of “customer-centricity, valuing hardworking individuals, and maintaining a long-term commitment to arduous endeavors.” Grounded in clients' practical needs, it has broken through traditional design limitations by abandoning conventional cylinder valves and rotating baffle configurations. Balancing economic efficiency with operational flexibility, the company has innovatively developed the world's first ultra-supercritical 660MW multi-stage high-parameter adjustable extraction steam turbine featuring dual intermediate pressure cylinders.
During the development and design of the unit, to meet the steam supply demands of ultra-high pressure, high pressure, and low pressure categories, the R&D team scientifically selected extraction points and precisely formulated control strategies, ensuring the design solution possesses high engineering feasibility. Through close integration with actual production, installation, and operation phases, and focusing on safe, efficient, and flexible operation, the project achieved three industry firsts:
Pioneered the technology for interconnecting steam supply valve zones with ultra-high-pressure heating systems, Expanded the unit's ultra-high-pressure heating capabilities; leveraging the company's precision-adjustment capabilities Patented Technology for Medium-Pressure Main Steam Regulating Combined Valve Achieve deep coupling with the boiler to realize optimal high-pressure extraction at the optimal position; Innovatively adopts a “dual medium-pressure cylinder” design, Significantly enhanced the flexibility of low-pressure extraction regulation, substantially optimizing the unit's economic performance. Additionally, tailored to the project's specific requirements, a low-pressure module configuration capable of flexibly accommodating blades of various dimensions—including 940mm, 1040mm, and 1220mm—was selected to achieve optimal operational efficiency throughout the year.
Upon full commissioning of the Guoneng Fuzhou Phase II Project, annual power generation capacity will reach 12.6 billion kilowatt-hours. The project will deliver highly efficient and stable full-process industrial steam extraction with high flow rates, comprehensively enhancing the region's power and thermal supply capabilities. At the same time, This project innovatively integrates next-generation coal-fired power technologies by establishing a tripartite technical system centered on “high efficiency, flexibility, and low carbon emissions,” thereby fulfilling the power plant's fundamental role in peak-load regulation. At a 30% deep peak-shaving load, the unit can still stably deliver large-capacity multi-level heating. This aligns closely with national policies promoting cleaner and centralized heating in industrial parks, demonstrating the advanced, mature, and reliable nature of Harbin Electric's independently developed turbine designs. It provides robust support for the technological advancement of China's next-generation coal-fired power generation major equipment.
The successful development of a multi-stage, high-parameter adjustable extraction steam turbine has filled a technical gap in China's high-efficiency power generation sector for multi-stage industrial steam extraction. This innovation provides a groundbreaking solution for centralized multi-stage heat utilization scenarios in petrochemical complexes, integrated industrial parks, and similar facilities. Currently, this model is also deployed in projects such as Guoneng Qingshuiguan and Guoyuan Power Hami. Its innovative heating technology can be flexibly configured and widely replicated, continuing to lead the technological advancement of domestic cogeneration equipment.

The turbine thrust bearing serves as the core component for axial force balancing and rotor axial positioning within the unit.
How do turbine blades affect unit efficiency and safety?
First, understand a key fluid dynamics concept—the boundary layer. According to Prandtl's boundary layer theory, when viscous steam flows over a blade surface, an extremely thin fluid layer forms near the wall.
Hazards of Vacuum Leaks in Steam Turbines and Practical Leak Detection Methods
Condenser vacuum is a core parameter in the thermal cycle of steam turbine units. Vacuum leakage represents one of the most common failures in power plant turbines, occurring when external air or non-condensable gases infiltrate the condenser or vacuum system through equipment gaps.
Understanding Axial Displacement and Thermal Expansion in Steam Turbines
Shaft displacement Refers to the displacement of the shaft. Generally, axial displacement changes are small in magnitude. When axial displacement is positive, the shaft moves toward the generator.
How Does Main Steam Pressure Affect the Economic Efficiency of a Power Plant?
Main steam pressure refers to the pressure value of the high-temperature, high-pressure steam generated by the boiler before it enters the steam turbine, typically measured in megapascals (MPa).
