Desulfurization and denitrification are one of the important technical measures to prevent and control air pollution.
In November 2011, the Ministry of Environmental Protection website released the newly revised "Air Pollution Emission Standards for Thermal Power Plants" jointly issued by the Ministry of Environmental Protection and the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China. The standard came into effect on January 1, 2012. This is also the first time since 2003 that the Ministry of Environmental Protection has updated the air pollutant emission standards for thermal power plants.
Desulfurization: Generally refers to the process of removing sulfur from fuel before combustion and before flue gas emissions. It is one of the important technical measures to prevent and control air pollution. Generally, there are three desulfurization methods before combustion, during combustion and after combustion. Many flue gas desulfurization processes have been widely used in industry, and they are also of great practical significance for the treatment of exhaust gases from various boilers and incinerators.
Denitrification: In order to prevent excessive nitrogen oxide pollution caused by coal burning in boilers, coal is denitrated. It is divided into pre-combustion denitrification, combustion process denitrification and post-combustion denitrification. According to the formation mechanism of nitrogen oxides in cement kilns, there are two technical measures for reducing nitrogen and emissions in cement kilns: one is to control from the source and the other is to control from the end.
