This section primarily elaborates on the complete process flow and core equipment characteristics of waste-to-energy, analyzes its multiple comprehensive values such as ecological protection, energy conservation, carbon reduction, and social empowerment, and combines industry regulations and regulatory frameworks to outline the industry’s developmental advantages, existing challenges, and international trends.

In 2026, domestic waste-to-power projects are accelerating their deployment in Central and Southeast Asia, with over ten overseas projects concentrated in the first five months. The demand for waste heat recovery steam turbines has risen accordingly. Luoyang Hanfei Power focuses on the research and development of steam turbine units for waste incineration heat recovery, closely following the industry’s overseas expansion trend. By optimizing its products to meet specific needs, the company is seizing opportunities to supply equipment for overseas power plant projects.

As a core piece of equipment in the field of energy conversion, the steam turbine, with its efficient thermal-to-mechanical energy conversion capability, serves as the "power heart" supporting critical sectors such as power generation and industrial drives. From efficient electricity production in thermal power plants to energy-saving applications in industrial waste heat recovery, steam turbines are ubiquitous in multiple key sectors of the national economy. Their technological evolution and application upgrades profoundly influence energy utilization efficiency and industrial development patterns. This section will provide a comprehensive analysis of the core principles, structure, maintenance, and development trends of this essential industrial power equipment.

As the core equipment driving the development of modern industry and the energy sector, the birth of the steam turbine was no accident but rather a technological revolution that overturned the traditional power landscape. Tracing its origins, 1884 can be termed the "inaugural year" of the steam turbine, when British engineer Charles Parsons successfully developed the first practical steam turbine. This breakthrough shattered the limitations of traditional steam engines and opened a new chapter in the history of human power. Today, this "power pioneer," born over 140 years ago, continues to shine in fields such as electricity, industry, and maritime applications, serving as the "power cornerstone" supporting the development of the national economy.

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.
