Datang Sanmenxia power station - 2,900 MW Coal Power Plant in Henan, China

Datang Sanmenxia power station is a large coal-fired power plant located in Sanmenxia, Henan Province, China. With a capacity of 2,900 MW, it ranks among the significant coal power facilities in the region, supporting the energy demands of industrial and residential users. The plant operates under China's stringent emission standards, including the Air Pollution Prevention and Control Action Plan and the latest ultra-low emission requirements for coal power plants. Its technology likely includes supercritical or ultra-supercritical boilers to improve efficiency and reduce pollutant emissions, though specific details are not confirmed. As a major coal power station, it contributes to the local grid stability and economic development. The facility's environmental impact is managed through continuous emission monitoring and compliance with national regulations, reflecting China's ongoing efforts to balance energy security with environmental protection.

The plant's coal combustion generates CO2, SOx, NOx, and particulate matter, contributing to local and regional air quality concerns. Its location in Henan, a densely populated province, necessitates strict adherence to emission limits. The facility likely employs flue-gas desulfurization and selective catalytic reduction to mitigate pollutants, aligning with China's ultra-low emission standards for coal power plants.
