The main source of SO2 emissions in the production of building materials is from sulfides contained in fuels and raw materials. SO2。建材制品生产过程中排放的SO2主要来源于燃料和原料中所含的硫化物。 Nitrogen oxides Output 0.6815 0.6815 NOX. The emissions of NOx in the production of building materials come from two main sources. The first is the combination of N and O2 in the air at high temperatures, which is directly related to the temperature. The second is the low-temperature combination of N and O2 in the fuel, which is related to the concentration of O2. NOx。建材制品生产过程中排放的NOx来源主要两种途径。第一种，在高温状态下，空气中的N与O2化合而成，与温度高低有着直接关系。第二种，燃料中的N与O2低温化合而成，与O2的浓度有关系。 carbon dioxide (fossil) Output 586.3985 586.3985 CO2. The main sources of CO2 emissions in the building materials industry are from fuel combustion and raw material decomposition. Due to the lack of statistical data on industrial pollutant emissions, it is very difficult to collect data, and some data cannot be obtained directly. Therefore, an energy and raw material conversion method is used to obtain the data. CO2。建材工业CO2的产生途径主要来源于燃料燃烧和原材料分解。 particles (> PM10) Output 0.3002 0.3002 Dust, with an unspecified particle size, is treated as PM > 10 micrometers in diameter.
