Energy Saving and Environmental Protection of Huaneng Shang 'an Power Plant

Huaneng Shang 'an Power Plant pays more attention to energy conservation, environmental protection and technological transformation while becoming a big enterprise. The newly-built units in the third phase fully meet the requirements of the state for building energy-saving and environment-friendly power plants, and the effects of energy saving, water saving and environmental protection are very remarkable: First, the direct air cooling technology is applied to the 600,000 kW units with supercritical parameters for the first time in China. Compared with the traditional wet cooling unit, the third-phase unit can save 3 kilograms of water per power generation and more than 65.438 million tons of water per year, which provides a brand-new experience for building coal-fired power stations in water-deficient areas in China. Secondly, the optimization design bidding, the design of side coal bunker and the decentralized arrangement of control system are adopted to realize land and material saving and reduce the engineering cost. Third, the boiler design adopts low nitrogen combustion technology, and at the same time, a flue gas desulfurization device is installed to ensure that the flue gas emission reaches the standard.

At the same time, they also vigorously carried out technical transformation of old units and old equipment. Since 2005, two boilers in the first phase have been retrofitted with dry slag discharge, which, together with the reverse osmosis project of circulating water, can save 4.5 million tons of water and 5.5 million kwh of electricity every year. More than 10 high-voltage motors have been transformed by frequency conversion, saving electricity 10 million kilowatt hours every year; After the transformation of four electrostatic precipitators, the dust emission is reduced by 6.5438+0.3 million tons per year. At the end of June, 2008, the desulfurization facilities of two units in the second phase were completed as scheduled and passed the acceptance of Hebei Environmental Protection Bureau, which can reduce the emission of sulfur dioxide by 27,000 tons per year. Remarkable achievements have been made in energy conservation and environmental protection, and the competitiveness and sustainable development ability of Shang 'an Power Plant have been continuously improved.

Huaneng Shang 'an Power Plant is a directly affiliated backbone power plant wholly owned by Huaneng International Power Co., Ltd., located in Shijiazhuang, the capital of Hebei Province, 30 kilometers away from the urban area. The installed capacity of the power plant is 2.54 million kilowatts, of which 4 units have been put into commercial operation * * * 1.3 million kilowatts; The 2× 600,000 kW supercritical unit under construction is scheduled to be put into operation in the first half of 2008.
