Overview
Longsheng Cogen power station is a 60 MW coal-fired cogeneration plant in China, operated by Gongzhuling Shenglong Cogen Power Company. It provides both electricity and heat, supporting local industrial and residential needs.
Longsheng Cogen power station is a coal-fired cogeneration facility located in China, with coordinates 43.5175° N, 124.86° E. The plant has a capacity of 60 megawatts (MW), placing it in the small-to-medium scale range for coal power plants in the country. It is currently operational and owned by Gongzhuling Shenglong Cogen Power Company. As a coal-fired plant, Longsheng Cogen operates under China's national emission standards, which include stringent limits on sulfur dioxide (SO2), nitrogen oxides (NOx), and particulate matter. The plant likely utilizes subcritical technology, common for facilities of this size and age. Cogeneration (combined heat and power) improves overall efficiency by capturing waste heat for district heating or industrial processes. The plant's location in northeastern China, a region with cold winters, makes its cogeneration capability particularly valuable for district heating. Its 60 MW capacity contributes to local grid stability and supports economic activities in the surrounding area. The use of coal as a fuel source, however, results in a significant carbon footprint and local air quality impacts.
Environmental context
The plant's coal combustion produces CO2, SO2, NOx, and particulate matter, contributing to regional air pollution and greenhouse gas emissions. Its location in a populated area of northeastern China may expose nearby communities to health risks from emissions. The cogeneration design improves efficiency but does not eliminate the environmental drawbacks of coal. China's regulatory framework, including the Air Pollution Prevention and Control Action Plan, imposes emission limits and promotes cleaner technologies, but older plants like this may face increasing pressure to retrofit or retire.
Frequently asked questions
Longsheng Cogen power station is located in China, at coordinates 43.5175° N, 124.86° E. It is owned by Gongzhuling Shenglong Cogen Power Company.
Longsheng Cogen power station has a capacity of 60 megawatts (MW), making it a small-to-medium scale coal-fired power plant.
Longsheng Cogen power station uses coal as its primary fuel. It is a cogeneration plant, meaning it produces both electricity and heat.
Coal power plants in China must comply with national emission standards for SO2, NOx, and particulate matter, as well as the Air Pollution Prevention and Control Action Plan. New plants require stricter pollution controls, while existing plants may need retrofits.
Cogeneration, or combined heat and power (CHP), improves overall efficiency by capturing waste heat from electricity generation for heating purposes. This reduces fuel consumption and emissions compared to separate heat and power production.
