No. 2 × 1 million kilowatt unit expansion unit No. 2 is put into commercial operation on the off-site operation of Danhe Power Plant in Jiaozuo, Henan

During the 168-hour full-load trial operation, the boiler,Steam turbineThe main equipment such as generators and their auxiliary equipment operates safely and stably, with an investment rate of 100% for automatic, protection and main instruments. The main technical and economic indicators such as main shaft vibration, generator hydrogen leakage, and vacuum system tightness all meet excellent standards. Systems such as dust removal, desulfurization, and denitrification are simultaneously invested with the host. The emissions of smoke, sulfur dioxide, nitrogen oxides, etc. of the main environmental protection indicators meet environmental protection requirements, and environmental protection indicators are all better than ultra-low emission standards.

The large and small project of the Jiaozuo Danhe Power Plant is a key comprehensive energy enterprise built by State Power Investment Corporation in Henan Province.Henan Provincial Development and Reform CommissionThe first large-scale approvedThermal power project, it is also the first national science and technology support plan project undertaken by the Intermediate People's Court, "Development and Application of Ultra-Supercritical Units with High Efficiency and Wide Load Rate" to rely on. The project is located in the west of Tuyao Village, Xixiang Town, Qinyang City, Henan Province. The total investment of the project is 7 billion yuan. It uses a single-million-kilowatt ultra-supercritical coal-fired unit. The designed power supply coal consumption is 280 grams per kilowatt-hour, replacing the shutdown small unit. After the project is completed, it can save about 1.3 million tons of raw coal, save about 22 million cubic meters of water, reduce sulfur dioxide emissions by 40,000 tons, and provide sufficient electricity to the local area, which has good social and economic benefits.
