Description

technical field

[0001] The invention relates to an additive product suitable for use in coal-fired boilers in industries such as petroleum, chemical industry, electric power, thermoelectricity and metallurgy, in particular to a boiler coal-fired combustion-supporting desulfurization and denitrification agent composition. The invention also relates to boiler coal-fired combustion-supporting A preparation method of a desulfurization and denitration agent composition. Background technique

[0002] my country's air pollution is serious. According to data estimates, the main air pollutants emitted by coal combustion, such as soot, SO 2 , NOx, CO 2 etc., the total amount accounts for about 96% of the total fuel combustion emissions. Among them, the S0 emitted by coal combustion 2 Accounting for 87% of the total emissions of various pollution sources, followed by NOx accounted for 6% of the total emissions of various pollution sources. SO 2 NOx and NOx are the main causes of a...
