China once again broke the monopoly technology of Europe and the United States, so that the West directly called out, it turned out that China mastered the key technology of ultra-supercritical steam turbines and recreated millions of kilowatts of steam turbines. Steam turbines are the key equipment of thermal power plants and also important transmission devices, which are widely used in power generation, metallurgy, chemical industry and marine fields. The breakthrough in China's ultra-supercritical steam turbine technology not only represents The soaring strength of China's comprehensive industry, but also represents that in the field of precision large machinery, China is no longer constrained.

Steam turbine is a transmission device driven by high-temperature water vapor, and its development can be traced back to the 1st century AD. In the European Middle Ages, Italian scientists improved the steam turbine, adding blade drive devices to it, thus laying the prototype of modern steam turbines, and later Europeans gradually developed impulse steam turbines and reactionary steam turbines, until 1910, American scientists invented multi-stage steam turbines, and their technical principles have been used to this day.

At present, the most mainstream application of steam turbines is thermal power stations, in addition to metallurgy, chemical industry and shipbuilding applications, but it is not as dependent as thermal power stations. A group of steam turbines with excellent performance can greatly improve the power generation efficiency of thermal power stations, reduce the use of fuel, emit less greenhouse gases, and one of the important indicators to measure the technical content of a thermal power station is the performance of steam turbines.
After a long period of development, the steam turbine has now undergone a revolutionary change in technology, that is, the supercritical steam turbine. Ultra-supercritical steam turbine is the main steam chamber pressure of 25Mpa, the main steam temperature of 580 ° C of the general term of the steam turbine, this steam turbine compared to the ordinary steam turbine, has the advantages of high heat engine efficiency, low steam volume flow, but it has higher requirements for transmission blades and bulkhead materials, for a long time, ultra-supercritical steam turbine technology has been mastered by European and American countries.

China's million kilowatt class ultra-supercritical steam turbine came out, caused a sensation in the world, China's ultra-supercritical steam turbine is the world's highest transmission efficiency steam turbine, compared to European and American products, the steam turbine in the blade and pressure-resistant metal has a huge breakthrough, but also support multi-axis linkage and multi-cylinder parallel work, which is also the root cause of its high transmission efficiency. If the turbine can be mass-produced, China will replace the former Soviet Union as the country with the lowest coal consumption rate for thermal power generation in the world.
With the advent of China's million kilowatt-class steam turbines, it not only broke the monopoly position and technical blockade of European and American countries, but also benefited China's thermal power generation industry. At present, the power generation methods in various countries in the world are still based on thermal power generation, so the application prospects of high-performance steam turbines are very huge. At present, the proportion of thermal power generation in China is as high as 70%, and there is still a long way to replace thermal power generation with new energy power generation, during which time it is when the ultra-supercritical steam turbine shows its skills.
