With the increasingly serious greenhouse effect, excessive emission of greenhouse gases caused by human activities has attracted widely public attention. This paper revealed the mechanism of N2O generation and decomposition in fluidized bed combustion, pointed out the source of N2O, listed various factors affecting the N2O production, and finally proposed some technical measures for reducing N2O emission. Moreover, the latest researches about N2O reduction were reviewed and the research direction was pointed out, and powerful theoretic support is provided to energy saving and emission reduction.
Key words： N2O; fluidized bed boiler; factors; mitigation measurement
