Yulin Huitong Cogen Power Station: 100 MW Coal Cogeneration Facility in Yulin, China

Yulin Huitong Cogen power station is a coal-fired cogeneration facility located in Yulin, Shaanxi Province, China. With a capacity of 100 MW, it is considered a small- to medium-scale plant in the context of China's vast coal power fleet. The plant is owned by Yulin Huitong Power Generation Co. and is currently operational, serving the local energy and heating needs. As a coal-fired plant, it operates under China's national emission standards, which have become increasingly stringent in recent years. The Chinese government enforces limits on SO2, NOx, and particulate matter through the Air Pollution Prevention and Control Action Plan and the Ultra-Low Emission standards. Many coal plants in China have retrofitted with desulfurization, denitrification, and dust removal technologies to comply. Typical coal plants of this scale in the region use subcritical boilers. The plant's cogeneration capability enhances its overall efficiency by providing district heating, reducing the need for separate heat-only boilers. This contributes to local energy security and supports industrial and residential heating in Yulin. The facility's location in a coal-rich region of Shaanxi ensures a stable fuel supply, though it also ties the plant to the carbon intensity of coal. As China transitions toward cleaner energy, plants like this may face pressure to reduce emissions or adopt carbon capture technologies.

The plant's coal fuel source results in significant CO2, SO2, NOx, and particulate emissions compared to natural gas or renewable alternatives. Its location in Yulin, a city with a population over 500,000, means emissions can affect local air quality. The plant's 100 MW capacity places it in a moderate size range, and its age and technology (likely subcritical) may result in lower efficiency and higher emissions per MWh. Proximity to populated areas increases potential health impacts from air pollutants.
