At the first anniversary of the "Made in China 2025" announcement, China Electric Power Media Co., Ltd., together with Hebei Hongrun Nuclear Equipment Technology Co., Ltd. and Hefei Suihua Motor Technology Development Co., Ltd., held a symposium to promote the localization of auxiliary equipment for thermal power in Beijing. From the National Development and Reform Commission, relevant industry associations, and relevant users of the users conducted face-to-face exchanges on the problems encountered in the localization of thermal auxiliary machines.

As the trend of large-scale and cleanliness continues to deepen, 600,000 kilowatts and 1 million kilowatts of ultra-supercritical units have become China's main thermal power units. At present, the parameters, performance, and output of China's thermal power units have occupied the first place in the world.

The three major boilers, steam turbines and generators have been completely designed and manufactured independently, but there have been bottlenecks in the auxiliary machinery equipment and materials known as the “last mile” of localization of thermal power technology in the four major pipelines, high-end valves, and boiler water circulation pumps. Reliance on imports not only limits the construction of power stations to people, but also greatly increases the cost of power construction.

In recent years, in order to promote the localization of the four major pipelines, the National Energy Administration has convened a meeting for the localization of the super (super)critical thermal power generation unit's four major pipelines, and organized relevant companies to conduct joint research and development on key valves and four major pipelines of supercritical (super)critical thermal power units. .

According to the localization tasks of the four major pipelines, the National Energy Administration has formulated the “Localization Implementation Plan for Large-diameter Thick-walled Seamless Steel Pipes for Supercritical (Ultra-critical) Thermal Power Units” to further strengthen the organization and coordination of localization projects.

“The relevant national policies clearly require that in the next step in the construction of coal-fired power projects supported by coal-fired power plants, localization must be fully supported, especially the four major pipelines and key pump valves,” said the relevant person in charge of the Energy Bureau.

This is consistent with the development goals set out in "Made in China 2025".

The reporter learned that "Made in China 2025" has a more specific statement on the breakthrough of key components and key materials. “By 2020, 40% of core basic parts and key basic materials will be independently guaranteed, the situation subject to human beings will be gradually eased, and the core basic parts and components (components) and key basic materials that are urgently needed in industries such as power generation and power transmission and transformation equipment will be advanced. The technology has been popularized and applied. By 2025, 70% of the core basic components and key basic materials will be independently guaranteed."

To achieve the above objectives is inseparable from the joint efforts of government, industry, and research. The relevant person in charge of the National Energy Administration said at the symposium to promote the localization of thermal power auxiliary equipment that the current thermal power construction demonstration project has two directions. One is the construction of thermal power units with higher parameters, and the other is the construction of thermal power stations with full localization.

It is understood that the National Energy Administration has recently approved a comprehensive domestically produced thermal power construction project. This is considered by industry experts as a major move by China in advancing the localization of thermal power auxiliary engines.

Hongrun made use of the world's largest vertical extrusion machine (50,000 tons) combined with high-end P92 large-caliber seamless steel pipe produced by Baosteel Special Steel Co., Ltd. to pass the expert appraisal, indicating that the dependence on imported P92 steel pipe will be gradually broken. "To break the current situation in which about 90% of P92 steel is imported from thermal power stations, the core issue is to solve the problem of owners' perceptions of domestic equipment in thermal power plant construction," said Liu Chunhai, chairman of Hongrun.

The boiler water circulation pump was hailed as the "fourth largest host" of thermal power plants. In general, the thermal power plant is the "three major mainframes." The use of the "fourth largest mainframe" to locate the boiler water circulation pump shows its significance in thermal power plants. “Our boiler water circulation pump market share is only about 1%, which is not compatible with our manufacturing capacity.” Yao Chongquan, chairman of Hefei Suihua Motor Technology Development Co., Ltd. said.

Suihua Motor is the first company in China and the third company in the world that can independently design and manufacture and meet the needs of subcritical, supercritical and ultra-supercritical large-scale generating units. For more than 10 years, the company's boiler water circulation pumps are operating normally.

Experts believe that although the development of thermal auxiliary equipment in China has achieved breakthroughs, due to the constraints of various factors such as user habits and user bias, localization promotion still has a long way to go and needs all parties to jointly promote, especially Need to work hard on top-level design. The industry believes that through expert in-depth discussion of the status quo of domestic production of thermal power equipment and existing problems, it will provide intellectual support for the promotion of China's four major thermal power generation pipelines and furnace pumps.

“It is a long process to break the monopoly of foreign capital. In particular, it is necessary for the country to formulate corresponding policies. For example, guide the power generation companies to try a large number of domestic steel pipes, including P92,” said Meng Yanhui, director of the Industry Service Department of Power Generation Equipment Center of China Machinery Industry Federation. . It is reported that China is actively supporting the launch of the “Five-Integration of Government, Production, Research and Application” to break through the engineering and industrial bottlenecks of key basic materials and core basic components.
