N2O emissions from combustion in circulating fluidized bed

The emission of N2O from atmospheric fluidized bed coal combustion is usually in the order of 100-200 ppm, wheras the corresponding emission from flame combustion is low, only a few ppm. Therefore, the formation and destruction of N2O in atmospheric fluidizrd brd combustion needs further attention. This review summarizes the experience gained concerning the emissions of N2O from circulating fluidizrd brd boilers with emphasis on the work done at Chalmers University of Technology.
