Zhangjiakou eliminated 623 coal-fired boilers in the first half of the year

　　Eliminating coal-fired boilers is an important measure to promote the prevention and control of air pollution and improve environmental air quality. Since the beginning of this year, the city has carried out intensified efforts to eliminate coal-fired boilers. In the first half of the year, the city eliminated 623 coal-fired boilers, laying the foundation for the steady improvement of the city’s air quality.

　　Comprehensive investigation of coal-fired boilers was carried out. In-depth investigation of the elimination of coal-fired boilers and the conversion of gas to electricity, etc., by verifying the base number of boilers and the electricity consumption of gas used in the elimination and transformation of boilers, forming a complete list of boiler types, methods of elimination and transformation, rectification, acceptance, and responsible persons, and doing it properly The accounting and filing of coal-to-electricity and coal-to-gas consumption will lay the foundation for the next step of eliminating coal-fired boilers. Further promote the elimination of coal-fired boilers.

　　In recent years, our city has requested that new coal-fired boilers be banned within the main urban built-up areas and urban-rural junctions, county built-up areas and economic development zones (industrial parks, demonstration areas), and 35 steam-ton or less coal-fired boilers are prohibited in other areas. At the same time, in areas covered by the central heating pipe network, priority will be given to central heating. Those that cannot be integrated into central heating shall actively and steadily promote the conversion of coal-fired boilers to electricity and gas, and promote the utilization of photovoltaic, solar thermal and industrial waste heat. Various heating methods further prevent and control pollution from the source.

　　Strongly promote the in-depth treatment of boilers. Vigorously control bulk coal pollution, comprehensively transform coal-fired boilers and coal-fired generating units, and implement low-nitrogen combustion reforms for coal-to-gas boilers. In addition, online monitoring devices are installed for coal-fired boilers and networked with environmental protection departments to realize synchronous operation and real-time monitoring of production facilities and governance facilities to ensure that the city's air quality is stable and up to standard.
