Overview
Jiangyin Cogen power station is a 150 MW coal-fired cogeneration facility in Jiangyin, China, owned by Jiangyin Cogen Power Co. It provides both electricity and thermal energy to local industries.
Jiangyin Cogen power station is a coal-fired cogeneration plant located in Jiangyin, Jiangsu Province, China. With a capacity of 150 MW, it falls into the small-to-medium scale range for coal power plants in China. The facility is owned and operated by Jiangyin Cogen Power Co and is currently operational. The plant utilizes coal as its primary fuel, a common choice for cogeneration facilities in China that supply both electricity and process heat to nearby industrial users. While specific technology details (such as subcritical or supercritical) are not disclosed, many Chinese coal plants of this vintage employ subcritical technology. The facility operates under China's national emission standards, which have become increasingly stringent in recent years, requiring desulfurization, denitrification, and particulate control systems. As a cogeneration plant, Jiangyin Cogen power station plays a key role in improving overall energy efficiency by capturing waste heat for industrial use. Its location in the industrial city of Jiangyin, part of the Yangtze River Delta economic zone, means it supports local manufacturing and chemical industries. The plant's environmental impact is mitigated by modern pollution control equipment, though coal combustion still contributes to regional air quality concerns.
Environmental context
The plant's coal combustion produces CO2, SOx, NOx, and particulate matter, contributing to local and regional air pollution. Jiangyin is a densely populated industrial city, so emissions may affect nearby communities. However, Chinese regulations require coal plants to install flue-gas desulfurization, selective catalytic reduction, and electrostatic precipitators, which reduce harmful pollutants. The plant's cogeneration design improves overall efficiency, lowering fuel consumption per unit of useful energy output compared to separate heat and power generation.
Frequently asked questions
Jiangyin Cogen power station is located in Jiangyin, Jiangsu Province, China, at coordinates 31.8436 N, 120.4103 E.
The facility has a capacity of 150 megawatts (MW), which is considered small-to-medium for a coal power plant in China.
The plant is owned by Jiangyin Cogen Power Co, which operates the facility.
Coal power plants in China must comply with national emission standards for SO2, NOx, and particulate matter, enforced by the Ministry of Ecology and Environment. Plants are required to install desulfurization, denitrification, and dust removal equipment.
Cogeneration, or combined heat and power (CHP), simultaneously produces electricity and useful thermal energy from the same fuel source, increasing overall efficiency to 70-90% compared to separate generation.
