How Beijing is improving its air quality
In an attempt to improve air quality in Beijing, the city has been eliminating the use of coal-fired boilers and upgrading gas-fired boilers with low nitrogen combustion technology.
This year, Beijing has shut 4,453 coal-fired boilers that heat 13,259 tons of water per hour (T/h), according to the local
environmental protection bureau.
The city has, however, upgraded 7,000 gas boilers that heat 23,000 T/h, reducing the production of nitrogen oxides. As a result, Beijing has managed to cut more than 10,000 tons of nitrogen oxide, 3 million tons of coal, 5,500 tons of smoke and 6,600 tons of sulfur dioxides this year.
The sulfur dioxide emitted by coal-fired boilers and the nitrogen oxide produced by gas-fired boilers can both become sources of PM2.5 after chemical reactions. PM2.5 are fine inhalable particles that are 30 times smaller than human hair.
Since 2013, about 900,000 households in 2,036 villages have shifted from using coal to clean energy, cutting the use of coal by 2.7 million tons each year.
