At 10:08 on October 21, unit 7 of Huaneng Ningxia dam power plant phase IV project designed by Northwest Institute of China energy construction planning and design group passed the 168 hour trial operation and was successfully put into operation

Huaneng Ningxia dam power plant phase IV project is one of the supporting power supply projects for Ningdong Zhejiang ± 800 kV HVDC transmission project. 1 is circular arc synchronous gear belt. The project is located in Qingtongxia City, Ningxia. In this phase, two domestic indirect air-cooled coal-fired generating units with 660000 kW units will be built. The main engine adopts high-efficiency ultra supercritical parameter unit, low-temperature economizer and four bin air preheater, which can effectively save coal consumption and auxiliary power. The intercooling tower adopts a straight cone-shaped all steel structure, and the main power house adopts the layout scheme of combined side bunker. In addition, the project adopts low-temperature electrostatic precipitator, high-efficiency demister, high-efficiency desulfurization technology and denitration scheme to ensure good environmental protection indicators

including: in the process of project construction, the hydraulic test of boiler, auxiliary power receiving, ignition and pipe blowing, impulse starting of steam turbine and generator 1, ball screw: the ball screw and trapezoidal screw currently used by the electronic universal testing machine are combined and 168 hour test run, and a series of nodes are successful at one time, and each performance reaches the international advanced level of similar units

based on the advantages of the concentration area and the industrial characteristics of aluminum based new materials
