On the afternoon of May 9, the F-class 50-megawatt heavy-duty gas turbine HGT51F, independently developed by Hangzhou Turbine Power Group Co., Ltd. (hereinafter referred to as “Hangzhou Turbine”), was successfully ignited in the test center’s workshop. Heavy-duty gas turbines, regarded as the \"gem on the crown\" of the equipment manufacturing industry and the \"heart of the energy sector,\" are energy conversion devices that transform the chemical energy of fuel into power. Characterized by high efficiency, low emissions, and rapid start-up and shutdown, they are widely used for power generation on land and for regulating peak loads in power grids. Heavy-duty gas turbines present great challenges in terms of design, manufacturing processes, and materials. Their design and production involve cutting-edge technologies such as high-temperature materials, precision machining, and aerothermodynamics, reflecting a **high level of industrial sophistication. It is reported that the HGT51F is Hangzhou Steam Turbine’s first heavy-duty gas turbine with fully independent intellectual property rights, having overcome key core technologies such as high-temperature heat components, control systems, and overall system integration ； A systematic method for the independent design of core gas turbine components and systems has been established. The three core components – the combustion chamber, turbine, and compressor – as well as the control system, have all completed their component tests. Through tests such as those at full temperature and pressure, more than 10 key performance indicators have reached international advanced levels. Ye Zhong, Secretary of the Party Committee and Chairman of Hangzhou Steam Turbine, said that in 2014, Hangzhou Steam Turbine officially launched a project to develop 50MW-class domestic gas turbines. More than 100 highly skilled researchers were assigned to this effort, and nearly one billion yuan was invested in research and development. A series of significant technological advancements were achieved, including tests on the compressors of civil gas turbines as well as tests on hydrogen combustion in combustion chambers under full temperature and pressure conditions. This led to the creation of a complete technical cycle that covered everything from the localization of core components to the integrated testing of the entire turbine. It is said that once it is put into operation officially in the future, this gas turbine’s combined cycle will be able to generate around 70,000 kilowatts of electricity per hour, with an annual output of approximately 400 million kWh – enough to meet the electricity needs of a medium-sized county for one year.
