Shanghai kesby signed the world's largest boiler feed pump
Recently, Shanghai kesby Pump Co., Ltd. successfully signed the feed pump contract for phase II 1x1350mw project of Shenneng Anhui Pingshan power plant. It is understood that the phase II 1x1350mw project of Shenneng Anhui Pingshan power plant is a national coal-fired unit demonstration project. After completion, it will become the world's largest coal-fired generator unit with single unit capacity (1350mw) and create a new record for the power generation efficiency of coal-fired generator units in the world. The feed pump system also adopts a unique layout, and the feed pump will become the largest boiler feed pump used in coal-fired units so far.
According to the contract, Shanghai kesby Pump Co., Ltd. will provide one main feed water pump (chtd11), two booster pumps (ynk500 / 590), relevant valves, gearbox and other accessory equipment for the project.
It is reported that the world's largest coal-fired unit is a project built in the United States in the 1980s, with a single unit capacity of 1300mw. As a national conventional thermal power demonstration project, the second phase of Shenneng Anhui Pingshan power plant has a unit capacity of 1350mw. After completion, it will become the world's largest conventional coal-fired thermal power unit, and the unit system parameters are greatly improved compared with 1300mw units in the United States.
The second phase project of Shenneng Anhui Pingshan power plant will be optimized in combination with the experience of Waigaoqiao No. 3 power generation company and many power plants that have been put into operation at home and abroad, and a number of new system designs will be adopted. Compared with conventional thermal power units, the biggest difference is that the high and low split shaft arrangement scheme of steam turbine proposed by Professor Feng Weizhong based on foreign unit experience and theoretical optimization is adopted. This scheme will greatly shorten the main steam pipeline and reheat steam pipeline, greatly reduce the loss of needle aid pipeline, and improve the efficiency of power generation system. The expected system power generation efficiency of the project is 49.5%, while the design power generation efficiency of the most advanced power plant system is about 48%. This efficiency will refresh the efficiency record of the global conventional thermal power system and greatly reduce the coal consumption for power generation.
