The fifth generation high-efficiency reaction turbine technology with intelligent design as its core is developed in cooperation with universities such as Xi'an Jiaotong University, based on the digestion and absorption of foreign high-efficiency reaction turbine technology. The fifth generation steam turbine has reached the advanced level in China and can meet various market demands for steam turbines such as solar thermal power generation, air turbines, waste to energy generation, combined cycle, biomass, and cogeneration, achieving high efficiency, environmental protection, and digitization. It has the technical characteristics of high thermal efficiency, compact structure, fast installation, rapid start-up, superior performance, and high reliability. The thermoelectric conversion efficiency of the product is 6-11 percentage points higher than the current domestic products of the same model, which is at the world's advanced level. The external dimensions of the product are 20-30% smaller than the current domestic model, and the weight is reduced by 30-50%; And axial exhaust plane layout can be adopted.
