Chemical kinetic modelling of the effect of NO on the oxidation of CH4 under fluidized bed combustor conditions

In this work, an existing reaction mechanism is adapted and tested for its capability to describe the NO sensitised oxidation of CH(sub4) under conditions relevant to fluidised bed combustion. NO lowers the ignition temperature to about 300C under the conditions investigated. 3 different oxidation p...

Description
Summary:In this work, an existing reaction mechanism is adapted and tested for its capability to describe the NO sensitised oxidation of CH(sub4) under conditions relevant to fluidised bed combustion. NO lowers the ignition temperature to about 300C under the conditions investigated. 3 different oxidation paths have been identified and are subsequently discussed. Their relative importance strongly depends on combustion temperature, indicating that the presence of NO(subx) significantly affects the oxidation of volatiles in fluidised bed combustion.
