In the bustling production area of a steel mill in northern China, thermal energy generated by the combustion of industrial gas is transferred to high-temperature steam, driving a powerful steam turbine to operate at high speed and efficiently convert waste heat into clean electricity—this is the daily operation scenario of the country's first 100-megawatt high-efficiency subcritical gas-fired power generation steam turbine. As a core piece of equipment for energy recovery and utilization in the steel industry, this steam turbine can not only withstand the harsh operating conditions of high temperatures, heavy loads, and continuous operation in steel mills but also delivers power with ultra-high energy efficiency, making it an indispensable industrial "heart" in the metallurgical sector. The technological breakthroughs behind its research, development, and manufacturing have also addressed long-standing challenges in the industry.

As a core pillar in the energy equipment sector, China's steam turbine industry is entering a critical period of high-quality development opportunities. Supported by continuous national policy incentives and deep technological innovation iterations, the industry is advancing with green transformation, intelligent upgrading, and high-end development as its core directions. It plays a pivotal role in safeguarding national energy security and advancing the realization of the dual carbon goals, steadily expanding its market scale and continuously enhancing its industrial competitiveness.

In recent years, domestically developed steam turbines have achieved breakthroughs in over a hundred core technologies. The double-medium-pressure cylinder units by Harbin Electric Corporation and the high-efficiency boiler feed pump turbines by North Heavy Industries have successfully filled critical domestic gaps. Leveraging its expertise in waste heat recovery technology and auxiliary equipment manufacturing, Luoyang Hanfei Power has deepened its focus on niche sectors, achieving remarkable business outcomes and contributing to the green energy transition through technological innovation.

On January 20, the steam turbine unit for the Anduo 100 MW tower-type solar thermal power station, independently developed by Dongfang Turbine, was successfully shipped. This unit overcomes the extreme operational challenges at an altitude of 4,650 meters and incorporates multiple core technologies, filling a gap in the industry. Upon completion, the project will deliver significant environmental and energy benefits, marking a landmark achievement in China’s high-altitude solar thermal equipment manufacturing capabilities and providing an exemplary model for clean energy development.

Harbin Electric Turbine Co., Ltd. has successfully started up the country's first high-parameter dual-intermediate-pressure cylinder extraction unit independently developed by the company in Fuzhou. The unit's thermal efficiency has increased by 3%-5% compared to traditional models, demonstrating outstanding environmental performance and adaptability. This breakthrough consolidates China's technological leadership in the relevant field, contributing to the upgrading of regional combined heat and power (CHP) systems and advancing the achievement of the "dual-carbon" goals.
