Abstract
NOx emission from coal combustion can be reduced through measures during combustion, cleaning of the flue gases or a combination of both. There is currently a total installed capacity of over 150 GWe equipped with combustion measures, mainly low NOx burners and air staging in furnace. The rates of NOx reduction in, for example, the FRG have been 25–40%. Higher reduction rates have been obtained with advanced low NOx systems. To achieve further NOx reduction, flue gas treatment is necessary. The most common process presently in use is selective catalytic reductions (SCR). A capacity of 35 GWe was equipped with SCR by the end of 1989. Most SCR plants in operation are designed to achieve about 80% NOx reduction to meet emission standards of 200 mg/m3.
