Mathematical modeling of fluidized bed combustion. 4:N_2O and NOx emissions from the combustion of char

摘要

Batch experiments were conducted to investigate the emissions of carbon oxides and nitrogen oxides from the combustion of char prepared from a commerical coal in a bubbling fluidized bed. Combustion gases escaping from the surface of the bed were sampled and analyzed for N_2O, NO, NO_2, CO and CO_2 as a function of time by means of a Fourier Transform Infrared Spectrometer. The experimental variables Include char size and loading, inlet oxygen concentration, inlet CO concentration and bed temperature.
