TLDR
In this paper, a novel combustor without flame is proposed by employing chemical-looping reactions, where NiO particles mixed with YSZ (yttria-stabilized zirconia) have very good properties for the oxygen carrier in the loop.Abstract:
A novel combustor without flame is proposed by employing chemical-looping reactions. Here we report the promising results on the novel combustor by kinetic and crystallographic study. We found that the NiO particles mixed with YSZ (yttria-stabilized zirconia) have very good properties for the oxygen carrier in the loop with respect to the reaction rate, conversion, and physical strength; especially the rate of oxidation of Ni is increased significantly. Furthermore, we observed that NOx was not generated in this combustor. Another significant feature, concerning the greenhouse impact, is that CO2 can easily be recovered.read more
