In the past two years, we have been unable to speed up the transformation of industrial coal fired boilers in terms of environmental protection to catch up with the speed of change in environmental policy. Basically, many boilers are undergoing a series of "build-rebuild -again", frequently changes in policies often make enterprises feel at a loss what to do, and last they are faced with being shut down". Recently, at the working meeting of "research on ultra-low emission technology of coal-fired boilers" Organized by China urban heating association, many enterprise personages attending the meeting talked about the ultra-low emission transformation work of coal-fired heating boilers promoted in the past two years.
With the increasingly urgent situation of air pollution prevention and control, around the implementation of the winter clean heating plan in the northern region, China has set off a wave of elimination of coal-fired boilers and ultra-low emission reform. Following the release of the latest “Boiler Air Pollutant Emission Standard” (GB13271-2014) on May 16, 2014, Beijing, Shanghai, Tianjin, Chongqing, Guangzhou, and other places successively revised and revised the local boiler air pollutant discharge standards. In addition, Guangdong, Shaanxi, Hebei, Shandong, Hangzhou and other places have also issued the "Consultation Draft" for local boiler air pollutant discharge standards. According to complete statistics, more than 10 provinces including Gansu, Henan, Shandong, and Jiangsu have successively announced subsidies for industrial coal fired boilers.
In order to achieve the goal of air pollution control as soon as possible, all regions are doing their best to carry out comprehensive control of industrial coal fired boilers. Accelerating the elimination or replacement of small coal-fired boilers, and at the same time, with the higher than the national standards and requirements for boiler air pollutants discharge, carry through boiler registration system and online control, etc. We have given great impetus to ultra-low emission renovation of medium and large coal-fired boilers.
In fact, the above standards are far lower than current national standards for the emission of air pollutants from coal-fired boilers and even far lower than the national standards for the mission of gas boilers. It’s said that the region also implemented the source control strategy, the boiler coal sulfur content, ash content and other indicators have also been strictly limited. At the same time, in order to meet the needs of environmental protection in a special period time, we have also introduced more stringent emergency plans for emission targets. Some places even proposed that industrial coal fired boilers with less than 100 tons of steam should be shut down, and this is not an isolated case across the country.
