Huaneng Beijing Thermal Power Plant Phase III plant operating F5 gas turbine
'5-4-3-2-1', at 18:18 on November 12, 2017, along with the sonorous and powerful countdown command of the power plant commissioning commander, along with the tears of excitement from Dongfang Electric Gas Turbine Co., Ltd., Huaneng Beijing Thermal Power Plant The third phase of control room sounded the applause and applause tide, carrying the eastern electric gas turbine people hope that the first set of domestic M701F5 heavy gas turbine successfully completed 168 hours of trial operation, successfully put into commercial operation.
M701F5 Heavy-Duty Gas Turbine As the first Eastern-Mitsubishi F-class gas turbine in China, the Huaneng Beijing Thermal Power Plant Phase III project, supplied by Dongfang Electric Corporation, is the major project of the People's Livelihood for Beijing Municipal Government and the center of Beijing Southeast Heat Supply Core project, shoulder the coal machine replacement, energy saving and emission reduction for the capital of millions of households to provide a steady stream of green power and green heating sources, to create the capital of clear water blue sky task .As the capital of key projects, the project is not only the practice of Dongfang Electric Group ' 12345 'development strategy is an important starting point, but also an important carrier in implementing Xi Jinping's new era of socialism with Chinese characteristics.
Huaneng Beijing Thermal Power Plant Phase III
F5 heavy-duty gas turbine main features
More power
M701F5 heavy-duty gas turbine output power is much better than the M701F4 unit, assuming that the annual running time of 4000 hours, compared to M701F4 unit, a set of M701F5 two drag a unit annual generating capacity will increase 360 million degrees.
higher efficiency
At present, the efficiency of advanced F-class gas-steam combined cycle units put into operation in China is about 59.0%. The efficiency of M701F5 units is close to 61%. After heating, the heating capacity and power generation output are higher than those of F class units in China.
More reliable performance
The M701F5 gas turbine is based on the M701F4 with a total operation time of more than 220,000 hours. The M701F5 is a more reliable equipment that combines the advanced technologies of the G and J gas turbines. The performance parameters belong to the world class F units The highest level.
More advanced flow and cooling technology
F5 gas turbine improved F4-type compressor mid-stage compressor to the last stage of the leaves, at the same time using the J-turbine turbine technology, under normal circumstances, the turbine inlet temperature is higher, the higher the efficiency of the gas turbine F5 F series of the latest upgraded version of the upgraded unit turbine initial temperature reached 1500 ℃, is the highest level of the same type of gas turbine models.
Higher performance materials
High-performance high-temperature materials and excellent cooling technology combine to not only improve the performance of the unit, but also reduce the unit maintenance costs.
More energy saving and environmental protection
Air-cooled combustor technology, which has been tested by actual operation of a GAC-type gas turbine, solves the problem of NOx (NOx) emissions and combustion stability. Although the combustion temperature of the M701F5 unit is significantly increased, M701F4 unit, the reduction of nitrogen oxide emissions per kWh of about 1.5%.
Careful service - to achieve the solemn commitment to users
Excellent service has always been a bright card of Dongfang Electric. The achievements of the third phase project of Huaneng Beijing Thermal Power Plant have reflected the responsibility and responsibility of Dongfang Electric Gas Turbine and realized their solemn commitment to users.
F5 heavy duty airport installation
During the installation of the unit, F5 heavy gas turbine adopts separate transportation and on-site double-assembly, and the quality of gas turbine reassembly will directly affect the operation quality of the gas turbine. Dongfang Electric attaches great importance to sending two quality inspectors and one expert respectively , The entire track to control the quality of the installation to ensure that the quality of the completion of the gas turbine refueling work.
During commissioning of the unit, the F5 heavy-duty gas turbine was successfully commissioned from the first main-plant motor on August 4, 2017 and started successfully on August 28, 2017. It took only 24 days to create a miracle in power plant commissioning work. The acquisition can not be separated from the hardworking and powerful technical support of Dongfang Electric Technical Service Team.
When only 3 days have passed from the steam turbine to the target node, commissioning of the main steam valve and control valve of the steam turbine control oil system has just begun. In the face of Dongfang Electric's newly designed self-designed heating steam turbine with SSS clutch, Efficient and high quality to complete the commissioning work to win this tough fight, the East Electrical and technical personnel will work with users, Xi'an Institute of hot work together to study drawing information, check the system, every day until 2 am, 3 o'clock, the final on time to control the oil system valve Adjustment is completed, there is no delay to turn the steam engine.
In order to ensure the success of the 19 th National Congress of the Communist Party of China, the power grid made proper arrangements to require Beijing Thermal Power Plant to carry a large load as much as possible before the National Day to verify the reliability of the generating units. To this end, Dongfang Electric's technicians and Mitsubishi experts worked continuously at the scene 30 hours, successfully completed combustion engine combustion test.
Service personnel are on-site commissioning
Dongfang Electric meticulous service has been the best return of safe and efficient high-quality operation of the unit. In the trial operation phase, the operation parameters of gas turbine, steam turbine and generator are excellent. The vibration of turbine shaft is controlled below 30um. The gas turbine shaft vibration is all controlled at 30um below, far better than the excellent indicator level of 70um, reached the optimal level of domestic heavy-duty gas turbine projects, fully reflects the high level of Dongfang Electric equipment manufacturing, quality control and service levels.
Forging ahead - leading the development of gas turbine industry
Heavy-duty gas turbine rotor
Gas turbine is one of the core power equipment of efficient energy conversion and clean utilization system in the 21st century and even longer period.Magnetic gas turbine is a typical high-tech-intensive products, is the embodiment of national manufacturing capability, its design and manufacturing difficulty of all mechanical Equipment first, known as the machinery manufacturing 'crown jewel'.
The government attaches great importance to the development of gas turbines. The gas turbines and aero-engines belong to the "two special projects" of the state, ranking the first of 100 major projects in the country during the 13th Five-Year Plan.
Dongfang Electric realized long ago: "Whoever holds the technology of heavy-duty gas turbines will have a new height in the equipment manufacturing industry and who will seize new markets."
In 2003, Dongfang Electric acquired the Mitsubishi (now Mitsubishi Hitachi) gas turbine manufacturing technology under a permit. In June 2005, Dongfang-Mitsubishi (now Mitsubishi Hitachi) first F-Class (M701F3) heavy-duty gas turbine was tested at Dongfang Steam Turbine After a successful announcement, China's first large-scale gas turbine with a domestic production rate of 46.5% was successfully launched in the East. In 2004, Dongfang Electric and Mitsubishi (now Mitsubishi Hitachi) set up a joint venture in Guangzhou to provide high-temperature hot parts (including combustion chambers, After the continuous exploration and innovation, in 2010, Dongfang Electric made high-quality M701F3 heavy-duty gas turbine put into operation in Fujian Putian Power Plant, the localization rate of the gas turbine reaches about 80% Created the highest domestic localization rate of gas engine.
To enhance its market competitiveness, Dongfang Electric and Mitsubishi (now Mitsubishi Hitachi) jointly launched the M701F4 gas turbine in 2009 and won the bid for the Beijing Gaobeidian project, which was put into operation in 2011.
As the market evolves, Dongfang Electric and Mitsubishi Hitachi have been deepening their cooperation to launch more advanced gas turbine products to users. In July 2015, Dongfang Electric obtained the first 2 sets of M701F5 gas-steam co-generation units from Huaneng Power International Co., Ltd. Cycle plant master order.
