In order to continue improving its air quality, Harbin, capital city of Northeast China’s Heilongjiang province, will work to upgrade or remove coal-fired boilers, according to information released by Harbin ecological environment bureau, on Feb 15.

Statistics reveal that in 2018, a total of 1,191 coal-fired boilers were removed in the capital, resulting in more days of air quality rated either “good” or “excellent”.

This year, Harbin plans to remove all coal-fired boilers with a heating supply capacity of 10 T/h or less in the downtown area of the city; it also plans to start removing coal-fired boilers with a heating supply capacity of 35 T/h or that cannot reach pollution discharge standards.
