The localization of the most thermal power auxilia

  • Detail

The localization of thermal power auxiliary equipment requires joint efforts of many parties

with the deepening trend of large-scale and cleaning, 600000 kW and 1million kW ultra (supercritical) units have become the main thermal power units in China. At present, the parameters, performance and output of thermal power units in China have occupied the first place in the world. On the first anniversary of the release of made in China 2025, China Power Media Co., Ltd., together with Hebei Hongrun nuclear equipment Technology Co., Ltd. and Hefei Wanhua Electric Machinery Technology Development Co., Ltd., held a symposium in Beijing to promote the localization of some auxiliary equipment for thermal power, which came from the National Development and Reform Commission and relevant industry associations, And the relevant person in charge of the user had a face-to-face exchange on the problems encountered in the localization of thermal power auxiliary equipment

with the deepening trend of large-scale and cleaning, 600000 kW and 1million kW supercritical units have become the main thermal power units in China. At present, the parameters, performance and output of thermal power units in China have occupied the first place in the world

the three main engines of boiler, steam turbine and generator have been fully able to design and manufacture independently, but there has always been a bottleneck in the auxiliary equipment and materials called the last mile of localization of thermal power technology, such as four pipelines, high-end valves and boiler water circulating pumps. Relying on imports not only makes the construction of power stations controlled by others, but also greatly increases the cost of power construction

in recent years, in order to promote the localization of the four pipelines, the national energy administration has held a working conference on the localization of the four pipelines of ultra (supercritical) thermal power units, and organized relevant enterprises to carry out joint research and development on the key valves and four pipelines of ultra (supercritical) thermal power units

according to the localization tasks of the four major pipelines, the national energy administration has formulated the implementation plan for localization of large-diameter thick wall seamless steel tubes for ultra (ultra) critical thermal power units to further strengthen the organization and coordination of the construction of localization supporting projects

relevant national policies clearly require that full support should be given to localization, especially the four pipelines and key pump valves, in the construction of supporting coal power projects in the next coal power base. The relevant person in charge of the energy administration said

this is consistent with the development goal proposed in made in China 2025

it is understood that "made in China 2025" has a more specific description of breakthroughs in key components and materials. By 2020, 40% of the core basic parts and components and key basic materials will be independently guaranteed, and the situation of being controlled by others will be gradually alleviated. The advanced manufacturing process of core basic parts (components) and key basic materials, which are urgently needed by the industry when the electronic universal testing machine shows defects, will be promoted and applied. By 2025, 70% of core basic parts and components and key basic materials will be independently guaranteed

achieving the above goals cannot be separated from the joint efforts of all sectors of government, industry, University, research and application. The relevant person in charge of the National Energy Administration introduced at the Symposium on promoting 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 fully localized thermal power packaging power stations

it is understood that recently, the national energy administration has also specially approved the comprehensive domestic thermal power construction project. This is regarded by industry experts as a major move in promoting the localization of thermal power auxiliaries in China

the high-end P92 large-diameter seamless steel pipe produced by Hongrun using the world's largest vertical extruder (50000 tons) and Baosteel Special Steel has passed the expert appraisal, marking that the dependence on imports of P92 steel pipes for ignition power will be gradually broken. In order to break the current situation that P92 steel in thermal power stations is about 90% imported, the core problem is to solve the cognition of the owners of thermal power stations on domestic equipment. Said liuchunhai, chairman of Hongrun

boiler water circulating pump is known as the fourth largest host of thermal power plant. Generally speaking, thermal power plants are the three main engines. Using the term of the fourth main engine to locate the boiler water circulating pump shows its important significance in thermal power enterprises. Our boiler water circulating pump market share is only about 1%, which does not match our manufacturing capacity. Said yaochongquan, chairman of Hefei Wanhua Motor Technology Development Co., Ltd

Wanhua Electric Machinery Co., Ltd. is the first enterprise in China and the third enterprise in the world that can independently design and manufacture boiler water circulating pumps to meet the needs of subcritical, supercritical and ultra supercritical large generator units. Over the years, the boiler water circulating pumps produced by the company have been in normal operation in conjunction with 32 logistics partners around the world, such as "four connections and one delivery", China Post and FedEx

experts believe that although the development of thermal power auxiliaries in China has achieved a breakthrough, due to the constraints of many factors, such as 1 ton or more, usage habits, user bias and so on, the promotion of localization still has a long way to go, which needs the joint promotion of all parties, especially the top layer design. The industry believes that the in-depth discussion of the current situation and existing problems of the localization of thermal power equipment by experts will provide intellectual support for promoting the localization process of the four major thermal power pipelines and boiler water pumps in China

breaking the monopoly of foreign capital is a long process, especially requiring the state to formulate corresponding policies. For example, power generation enterprises are guided to try a large number of domestic steel pipes, including P92. Meng Yanhui, director of the Industrial Service Department of the power generation equipment center of the China Machinery Industry Federation, said. It is reported that China is actively supporting the five in one joint research on politics, industry, University, research and application to break through the bottleneck of engineering and industrialization of key basic materials and core basic parts
