The core of environmental protection requirements for boiler burners lies in controlling emissions of nitrogen oxides (NOx), sulfur dioxide (SO2), and particulate matter (soot). Typically, this mandates the adoption of low-NOx combustion technologies to ensure that emissions comply with national standards for atmospheric pollutant discharge. These requirements primarily encompass NOx emission limits, high combustion efficiency (typically > 96%), the use of clean fuels, and the periodic monitoring of emission levels.
I. Key Technical Environmental Requirements
Low-NOx Retrofitting: Gas-fired boilers are required to utilize low-NOx burners or staged combustion technologies to reduce emission levels to meet national or regional regulatory limits (for instance, Beijing Municipality has established specific, explicit requirements regarding NOx emissions for certain categories of boilers).
Combustion Efficiency: The design combustion efficiency of the burner must exceed 96% to minimize pollution resulting from unburned fuel.
Flue Gas Monitoring: Industrial boilers with a thermal output of 14 MW or greater are mandated to install online flue gas monitoring equipment and establish network connectivity with the relevant environmental protection authorities.
II. Fuel and Emission Limit Requirements
Clean Fuels: The use of clean energy sources—such as natural gas and light diesel—is strictly mandated, while the use of non-clean fuels is expressly prohibited.
Emission Standards: In accordance with GB13271, the *Emission Standard of Air Pollutants for Boilers*, newly constructed boilers must adhere to stringent limits regarding the emission of particulate matter, sulfur dioxide, and nitrogen oxides.
III. Monitoring and Safety
Emission Monitoring: Boilers located in key environmental protection zones are required to install online monitoring systems in compliance with the *Administrative Measures for Automatic Monitoring of Pollution Sources*.
Chimney Height: The height of the chimney must meet environmental protection standards to prevent the localized concentration of pollutants in the immediate vicinity.
Specific emission limits in various regions may be subject to stricter "special emission limits," as stipulated by local ecological and environmental protection departments—particularly within the Beijing-Tianjin-Hebei (Jing-Jin-Ji) region and its surrounding areas.
