Natural gas boiler flue gas treatment

　　The degree of natural gas flue gas treatment is determined by local environmental protection requirements. The natural gas boiler itself emits less pollutants. For remote areas, ordinary gas boilers can operate normally. If the emission of nitrogen oxides is required, such as 30 mg per cubic meter The following needs to install low-nitrogen burners, economizers and other flue gas treatment measures.

Environmental requirements for gas boilers

　　The environmental protection requirements of gas-fired boilers mainly refer to whether the emission of nitrogen oxides reaches the local regulations. Natural gas itself contains relatively few pollutants. Environmental protection mainly depends on nitrogen oxides. Compared with the previous environmental protection requirements such as coal, biomass, and fuel oil Other fuels such as SO, NOX (in terms of NO), smoke and dust (TSP, PM10, PM2.5), carbon monoxide, and other types of pollutants produced by coal combustion. Different coal types also contain arsenic, mercury, copper, Heavy metals such as lead and chromium.
