摘要：

Selective non-catalytic reduction can meet the requirements of the new National Emission Regulation due to the low NOx emission characteristic of circulating fluidized bed boilers. In this work, ammonia was injected into the simulated circulating fluidized bed flue gas as a reducing agent. Optimum reaction conditions were obtained as: temperature of 920 degrees C, residence time of 0.6 s, and a normalized stoichiometric ratio (NSR1) of 1.5. H-2, as an additive, made a shift of 170 degrees C towards a lower temperature, while CH4 made a shift of 80 degrees C.
