摘要

The ignition and burnout of the volatiles in fluidized bed combustor are essential for its performance and emissions. NO_x are known to sensitize the oxidation of hydrocarons, CO, and H_2. This effect is relevant especially for fluidized bed combustors, which are operated at relatively low temperatures (i.e. about 850 deg. C). Different reaction mechanisms and modifications to existing mechanisms have been proposed in the literature to account for these low temperature interactions of NO_x and hydrocarbons. In this work, an existing widely used reaction mechanism is adapted and tested for its capability to describe the NO sensitized oxidation of CH_4 under conditions relevant to fluidized bed combustion.
