Shaanxi Huangling Power Generation Co., Ltd 2× 660MW power plant project is a major deployment to implement the national "west to East power transmission" and accelerate the transformation and development of Yan'an economic structure. It is a new ultra supercritical coal-fired unit with large capacity, high parameters and high efficiency. It is not only a key project in the 13th Five-Year Plan of Shaanxi Province, but also an important power support point for the ultra-high voltage DC transmission line from northern Shaanxi to Hubei. The project is located in Baishi Village, Diantou Town, Huangling County, covering an area of more than 560 mu. It is a typical pit-mouth powerplant with integrated production of coal and power. The power plant adopts a series of advanced technical schemes such as high-efficiency ultra supercritical, indirect air cooling two units and one tower, plasma ignition, full load SCR denitration and wet deep desulfurization to ensure that the coal consumption of power supply, auxiliary power consumption rate, flue gas pollutant emission index and other parameters to reach the leading level of similar units in China.It has the characteristics of green environmental protection, ultra clean emission, energy saving and high efficiency, advanced technology and so on.
