On November 2nd, the Shunyi District Municipal Administration Committee in Beijing announced an important development. As the host of the 2008 Olympic water sports events, the district has taken significant steps to improve environmental quality by completing three large-scale central heating centers in the eastern, western, and southern parts of the city. These facilities are now operational and were introduced for the 2007 winter heating season. A total of 7 million square meters of area is now covered by central heating, accounting for 85% of the entire heating demand in Shunyi. This initiative replaced 76 small residential boiler rooms, significantly reducing pollution.
The emission rate of soot per cubic meter has dropped below 10 milligrams, marking a major achievement in coal-fired heating and dust control. Shunyi's efforts have placed it at the forefront of environmental protection in both China and globally.
Previously, the district relied on 76 local boiler rooms, each equipped with 165 coal-fired boilers. These were scattered throughout the city, inefficient, energy-intensive, and lacked proper desulfurization systems, leading to severe air pollution. Starting in May 2006, the district invested 1 billion yuan to construct three modern heating centers in Chengdong, Chengxi, and Chengnan. These new centers use advanced computerized controls for coal handling, combustion, desulfurization, dust removal, slagging, and temperature and pressure regulation. This system ensures more stable operation and improved energy efficiency.
Environmentally, the centers employ advanced baghouse dust collection and wet desulfurization technologies, which have proven highly effective. According to measurements, soot emissions have been reduced to under 10 mg per cubic meter. This achievement places Shunyi’s coal-based heating and dust removal standards among the best in the world.
The shift to central heating also brings substantial benefits. It saves approximately 51,500 tons of coal annually, reduces ash production by 945 tons, cuts dust emissions by 9,649 tons, and lowers sulfur dioxide emissions by over 1,076 tons. Noise levels have also decreased by more than 70 units. As a result, the number of days with winter air quality above the second level has increased significantly.
Currently, the three large heating centers are undergoing final testing and are expected to provide timely heating services starting in November. This project marks a major step forward in sustainable urban development and environmental protection in Beijing.
