Application of the Numerical Techniques for …

The enclosure walls of the CFB combustion chamber are shielded by water tubes and a layer of refractory material similarly as in the BFB boiler. In the CFB boiler the combustion temperature is relatively low and uniform, kept in range 800–950 °C. The heat flux in the CFB boiler are lower than in the PC furnace, which is illustrated in Fig. 6.

Predictions of NOx/N2O emissions from an ultra

NO x and N 2 O emissions from an ultra-supercritical circulating fluidized bed (CFB) boiler were predicted using a two dimensional (2-D) comprehensive computational fluid dynamics (CFD) combustion model. This model was developed from a three dimensional model for a supercritical CFB boiler previously constructed by our group. Based on an analysis of the NO x and N 2 O conversion processes in a
