| Abstract | The present work investigated the synergetic effect of pyrolysis-derived char, tar and gas (py-gas) on NO reduction, which may occur in circulating fluidized-bed decoupling combustion (CFBDC) system treating N-rich fuel. Experiments were carried out in a lab-scale drop-tube reactor for NO reduction by some binary mixtures of reagents including char/py-gas, tar/py-gas and tar/char. At a specified total mass rate of 0.15 g.min(-1) for NO-reduction reagent, the char/py-gas (binary reagent) enabled the best synergetic NO reduction in comparison with the others. There existed effective interactions between char and some species in py-gas (i.e., H-2, CxHy) during NO reduction by pyrolysis products, meanwhile the tar/py-gas or tar/char mixture only caused a positive effect when tar proportion was necessarily lowered to about 26%. On the other hand, the synergetic effects were not improved for all tested binary reagents by increasing the reaction temperature and residence time.

Experiments were carried out in a lab-scale drop-tube reactor for NO reduction by some binary mixtures of reagents including char/py-gas, tar/py-gas and tar/char. At a specified total mass rate of 0.15 g·min~(-1) for NO-reduction reagent, the char/py-gas (binary reagent) enabled the best synergetic NO reduction in comparison with the others. There existed effective interactions between char and some species in py-gas (i.e., H_2, C_xH_y) during NO reduction by pyrolysis products, meanwhile the tar/py-gas or tar/ char mixture only caused a positive effect when tar proportion was necessarily lowered to about 26%. On the other hand, the synergetic effects were not improved for all tested binary reagents by increasing the reaction temperature and residence time. |
