What is the carbon monoxide limit standard for gas boilers?

The specific value of the carbon monoxide limit standard for gas boilers varies depending on the regulations and standards of different regions and countries. Based on current knowledge, here are some common carbon monoxide limit standards for reference:

United States: The Environmental Protection Agency (EPA) in the United States has set carbon monoxide limit standards for gas boilers, which vary depending on the type of boiler and fuel. Typically, the carbon monoxide emission limit for gas boilers ranges from 50 to 400 parts per million (ppm).

Europe: The European Union (EU) has established carbon monoxide limit standards for gas boilers known as the EN 15502 standard. Depending on the boiler's thermal output power and type, the carbon monoxide emission limit can range from 50 to 1000 ppm.

Please note that the above examples are from some common regions and may not represent the specific standards in all areas. The actual carbon monoxide limit standards may vary based on the regulations, standards, or guidance documents of the respective countries, regions, or relevant institutions.

In recent years, reducing nitrogen oxide (NOx) emissions from gas boilers has been an important environmental goal. There are variations in the standards for nitrogen oxide emission limits in different regions. Some regions, such as Beijing-Tianjin-Hebei, require a nitrogen oxide emission limit of 30mg for natural gas boilers, while the standard in the Yangtze River Delta region is 50mg. Some areas still adhere to the 80mg standard, depending on whether they have implemented low-nitrogen boiler retrofit policies. Nitrogen oxide is the main pollutant of concern in the emissions of natural gas boilers, rather than carbon monoxide (CO). The national requirement for carbon monoxide concentration in gas boiler emissions is 24ppm for normal operation, and the maximum allowable concentration of carbon monoxide in the workshop air is 30mg/m3, with an alarm set at 50ppm as a precautionary measure.
