Huang Rong, deputy general manager of the Gas Turbine Division of Harbin Power Station Group, and Yang Qiguo, executive deputy general manager of Harbin Electric Power Company, attended the review meeting. After review, experts agreed that the optimized design has reached the international advanced level, and the optimized steam turbine can replace the foreign D10 model. The success of the unit's autonomous design scheme indicates that Harbin has achieved a new leap in the gas-steam turbine combined cycle turbine, which is of great significance for improving the state-owned brand and promoting economic development.
The 9F gas-steam combined cycle unit optimized steam turbine reviewed by the company is a design and operation of several 9E gas-steam turbine combined cycle turbines. It analyzes, researches and produces multiple 9F gas-steam. On the basis of the turbine combined cycle unit D10 steam turbine, the design is autonomously optimized. The optimized design adopts full three-dimensional aerodynamic design technology, which greatly improves the aerodynamic performance of the cascade. The multi-tooth stepped steam seal structure of the high and medium pressure moving blade tip has obvious effect on solving the air leakage of the original unit, and the whole machine has a short manufacturing cycle. , economical, safe and reliable.
Xu Yingnan pointed out that the gas turbine power plants installed in China all use foreign technology. With the new requirements of the country for independent intellectual property rights and comprehensive economics, Haqi Company took the lead in proposing a localization plan in China to bring a good start to the national power development. At the same time, the strong market competition value of the Haqi unit is also required by the state. The development direction of power equipment manufacturing enterprises.
China began preparations for the production of gas turbines in 2002. By 2004, Harbin Power Station Group, Shanghai Electric Group, Dongfang Electric Group and Japan Mitsubishi, the United States GE, Alstom, Siemens and other companies have cooperated in two rounds of bidding. Among them, the Ha Power Station won 17 bids, the East won 10 bids, and the Shanghai won 9 bids.
Among the 12 units that have been completed, there are 10 Harbin Electric and 2 East, of which 3 have already generated electricity. In the second half of 2005, it is expected to complete 10 units. Harbin Electric Group adopted GE's D10 unit technology, and the users responded well. On this basis, in order to get rid of this prototype unit, Haqi has its own leading products, and the technicians have optimized and improved the unit, and successfully launched an optimized steam turbine with independent intellectual property rights in China.
Recently, the China Machinery Industry Federation organized relevant experts to hold a review meeting for the autonomous design of the 9F gas-steam turbine combined cycle unit of Harbin Steam Turbine Works Co., Ltd. in Harbin. Xu Yingnan, director of the China Machinery Industry Federation Power Generation Equipment Center, presided over the review meeting.
