Beijing city has transformed its coal-fired boilers with new energy in a move to clean up the city's foul air.
The capital city launched the "green energy project" as far back as 1998 to transform odd coal-fired boilers, typically producing about 7,000 tonnes of steam per hour, to be more environmentally friendly. By the end of 2015, Beijing had already phased out boilers totalling more than 60,000 tonnes of steam per hour, according to the Beijing Municipal Environmental Protection Bureau.
After completion at the end of this year, the green equipment will have helped slash Beijing's coal use by two million tonnes. That means an annual reduction of dust by about 30,000 tonnes, sulfur dioxide by about 16,000 tonnes and nitrogen oxide by about 5,000 tonnes.
The density of fine particulate matter PM2.5 in Beijing decreased by 10.1 percent year on year in the first nine months of the year, a local environment watchdog said last week.
Since 6 core districts have already accomplished the task of transforming, the project is currently focusing on suburban districts.
