In the field of major equipment in China, the current power generation equipment has the smallest gap with the international level, and is also the first to achieve a breakthrough. This evaluation is not easy, but it is appropriate. From the introduction of technology, digestion and absorption, to independent innovation, optimization and improvement, and then to leaps and bounds, and shoulders abroad, China's power generation equipment manufacturing industry has been proud of over 30 years, leaped through the struggle of leading power generation equipment companies, and witnessed major technical equipment. 30 years in the field. From the initial processing of raw materials, to map manufacturing, to joint design, joint bidding, and cooperative production, it is on an equal footing with large foreign companies and large companies, and today is in an advantageous position in the competition. Harbin Electric Group, Shanghai Electric Group, Dongfang Electric Group Leading companies, such as those who are brave enough to shoulder heavy burdens, have taken a unique technological path of introduction, digestion, absorption and self-innovation to fully drive the core competitiveness of China's power generation equipment manufacturing industry to a qualitative leap. Thermal power equipment clean and efficient Under the guidance of national policies, China's thermal power sector has opened a new era of clean and efficient power generation units and has become a landmark milestone for China's motor industry's independent innovation. From the late 1980s, China began to pay attention to the development of supercritical thermal power units and imported large-capacity supercritical units from abroad. In 1992, the first two sets of 600,000 kilowatts of supercritical thermal power units were installed at the Shidongkou Second Plant in Shanghai. This time the introduction of a combination of technology and trade, focusing on the introduction of the boiler and steam turbine supercritical technology and design calculation software, and through the participation in the design and other methods, trained a group of professional and technical personnel, for the localization of supercritical units work Ample preparation. In order to further promote the localization of supercritical units, China's research and development of 600,000 kilowatts of supercritical units was added to the 95th national major technical equipment development project in 2000, and a 2×600,000 kilowatt supercritical unit of Huaneng Qinbei Power Plant was determined. It is the first domestic 600,000 kilowatt supercritical unit demonstration project. With the two domestically produced 600,000 kilowatts of supercritical coal-fired units being put into operation one after another, their main equipments and important auxiliary engines have basically got rid of the dependence on foreign technology, and the localization rate of equipment has greatly increased. On the basis of the successful manufacture of the supercritical units, Harbin, Shanghai, and the East's three major power generation equipment manufacturing groups imported one million kilowatts of ultra-supercritical technology from companies such as Mitsubishi, Toshiba, Siemens, and Alstom, respectively, and are guaranteed by foreign companies. The performance of the cooperative approach, the final trial of successful million-kilowatt ultra-supercritical units. At present, China has successfully mass-produced 600,000 and 1 million kilowatts of supercritical and even ultra-supercritical thermal power units. After testing, performance indicators such as power generation efficiency, power supply standards, and coal consumption of China-made supercritical and ultra-supercritical units have been achieved. International advanced level. So far, China has become the world's most-injected multi-kilogram supercritical unit. At the same time, China has also continued to promote the use of large-scale air-cooled units, and in 2010 successfully put into operation the world's first (sets) million kilowatt-class ultra-supercritical direct air-cooled units. At present, China has become the country with the largest number of air-cooled units in the world. Experts once praised China's development of thermal power 600,000 kilowatts of supercritical units and 1 million kilowatts of ultra-supercritical units, and made four years of what the world has done for decades.
