摘要：

Interactions among SO(x), NO(x) and N2O, as well as among methods for their abatement, are discussed and guidelines for the development of N2O control in fluidized-bed combustion (FBC) are proposed. An integrated approach to pollution control is advocated rather than treatment of each pollutant separately. Improvements in operating conditions, start-up procedures and process control are examples of low-cost measures. However, innovative combustor design is required to produce low-emission systems that would meet increasingly stringent standards. Temperature optimization itself is insufficient; gas afterburning and solid-catalysed N2O decomposition are identified as the most promising measures. FBC flue-gas treatment is deemed unattractive, unless it can be made inexpensive and easy to install or retrofit.
