In 2014, seven government departments in China jointly published the Implementation Scheme for Comprehensive Promotion on Energy Saving and Environmental Protection for Coal Fired Boilers, mapping out that all prefecture-level or above cities in Beijing-Tianjin-Hebei Region and its surrounding area should phase out coal fired boilers of 10 steam tons per hour or below in their built-up areas and Beijing should abolish all coal fired boilers in its built-up areas by the end of 2015 unless necessary retaining; by 2017, all prefecture-level or above cities should phase out coal fired boilers of 10 steam tons per hour or below in their built-up areas in China and all prefecture-level or above cities in Hebei Province and Tianjin should phase out coal fired boilers of 35 steam tons per hour or below in their built-up areas. Upon this, authorities at different levels published their own Air Pollution Prevention and Control Action Plan respectively, so as to further specify and bring into action the target goals.

From the plan, it can be seen that Beijing-Tianjin-Hebei Region is the first tier under the most pressure to realize the goals. By 2015, it should close down all the coal fired boilers of 10 steam tons per hour or below and by 2017 all the coal fired boilers of 35 steam tons per hour or below. The second one includes Shanxi, Shandong etc. By 2015, they should close down all the boilers  of 10 steam tons per hour or below in urban areas. Provinces such as Shaanxi, Jilin and Heilongjiang will be on a more relaxed track. They plan starts to abolish boilers of 10 steam tons per hour or below from 2017 on.

After the closing down of small coal fired boilers, most of the facilities will be transformed into gas fired or electricity fired ones in industrial dispersed areas except those extremely outdated production facilities; in industrial cluster districts for chemical, papermaking, printing and dyeing, leather and pharmaceutical, most of the coal fired boilers will be replaced by the construction of cogeneration units gradually with high efficiency boilers being brought in.

Heat and power cogeneration will be the major heat supply for industrial production. It is measured that if 25 units of electricity and 50 units of heat are separately generated, it will consume 152 units of coals, but if cogenerated, it only consume 100 units of coals. Through combining heat and power generation, heat conversion efficiency can be raised from 50% to 75%, or even higher conversion efficiency can be achieved if adopting high efficiency boilers or further processing the coal combustion.
