For decades, coal has been the primary fuel used by power stations globally, despite its significant environmental impact. Environmental regulations in Europe, China, and India have become stricter, causing challenges for coal-fired power stations. Additionally, these plants are experiencing higher costs to comply with the new emission limits. To meet regulations, many power plants are adopting advanced technologies such as Selective Catalytic Reduction (SCR) and SNCR. These technologies are proven to significantly reduce nitrogen oxides (NOx) emissions, contributing to cleaner air and safer environments.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

During the combustion process, nitrogen reacts with oxygen at high temperatures to form nitrogen oxides (NOx), which include nitrogen monoxide (NO) and nitrogen dioxide (NO2). To meet stringent NOx emission limits, power plants implement DeNOx processes. In most cases, these processes involve the reaction of nitrogen oxides in the flue gas with ammonia or urea at elevated temperatures. Ammonia or urea reacts with NO and NO2 to convert them into nitrogen (N2), water vapor (H2O), and, in the case of urea, carbon dioxide (CO2). SCR systems are commonly used in large coal-fired power stations. SNCR is often deployed in smaller plants or those with Circulating Fluidized Bed (CFB) boilers.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

By implementing SCR and SNCR technologies, combustion plants can significantly reduce NOx emissions, which in turn mitigates environmental issues such as smog, acid rain, and visibility reduction. NOx emissions are also a significant contributor to respiratory health problems, so reducing them is a key step in improving public health. These DeNOx technologies not only help power stations comply with ever-stricter environmental regulations, but they also support sustainable energy practices by reducing the environmental footprint of coal-fired power generation.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
