On the afternoon of September 22, as another 600MW subcritical coal-fired air-cooled unit passed the 168-hour full-load test run, the two largest energy-saving and environmentally-friendly air-cooled units in China were all put into operation in Ning. This means that the key construction project in Ningxia, the 2×600MW subcritical air-cooling unit project of Huadian Ningxia Lingwu Power Generation Co., Ltd., invested and constructed by China Huadian Group Corporation, has come to a successful conclusion. The project only took 22 months, setting a new record for the commissioning of 600MW direct air-cooled units in China.
According to reports, the two units that have adopted international advanced air-cooling technology and desulfurization equipment have invested more than 5 billion yuan, and invested 260 million yuan more than traditional wet-cooled units. From the perspective of economic efficiency, the adoption of air-cooled island technology has increased operating and maintenance costs, even lower than that of traditional wet-cooled units. However, the 260 million yuan bought back is considerable energy saving, water saving, environmental protection and other benefits - compared with the traditional wet cooling unit, the annual water saving is 10 million tons, the flue gas desulfurization rate is over 98%, and the annual emission of sulfur dioxide is 22,600 tons. The use of urban water treatment to achieve zero discharge targets.
According to relevant persons from the Economic and Trade Commission of Ningxia Hui Autonomous Region, in 2005, the energy consumption per 10,000 yuan of GDP in Ningxia was 4.14, ranking first in the country. In recent years, Ningxia Hui Autonomous Region Economic and Trade Commission policy, dynamic supervision, shutdown and elimination of rigid measures and many other measures, Ningxia this year's 10,000 yuan GDP energy consumption is expected to fall by more than 4%, but congenitally insufficient "high energy consumption" industrial structure, making energy saving There is a long way to go. The advanced air-cooling technology of Huadian Ningxia Lingwu Power Generation Co., Ltd. has led the development direction of coal-fired power plants in the arid regions of northwest China, and explored a new road for a coal-rich and water-deficient area like Ningxia.
