This study delves into the combustion behavior of various lignite types within a circulating fluidized bed boiler(CFBB),with a primary focus on the impact of different bed material sphericity ratios(0.5,0.7,and 0.9).Utilizing bed material with a sphericity ratio of 0.9 sourced from theÇan power plant and verified through experimentation,the research reveals several key ***,furnace temperatures tended to rise with higher sphericity ratios,albeit with variations between lignite types,particularly highlighting the complexity of this relationship in the case of GLI-Tunçbilek *** levels in the combustion chamber remained consistent across different sphericity ratios,indicating minimal influence on pressure *** combustion efficiency,especially at the bottom of the boiler,was observed at lower sphericity levels(0.5 and 0.7)forÇan lignite,as reflected in CO_(2) mole *** NO_(x) emissions generally decreased with lower sphericity,the sensitivity to sphericity varied by lignite type,with Ilgın lignite showcasing low NO_(x) but high SO_(2) emissions,underscoring the intricate interplay between lignite properties,sphericity,and ***,this study advances our understanding of CFBB combustion dynamics,offering insights valuable for optimizing performance and emissions control,particularly in lignite-based power.

Here,furfural oxidation was performed to replace the kinetically sluggish O2evolution reaction（OER）.Pt-Co3O4nanospheres were developed via pulsed laser ablation in liquid（PLAL） in a single step for the paired electrocatalysis of an H2evolution reaction（HER） and furfural oxidation reaction（FOR）.The FOR afforded a high furfural conversion（44.2%） with a major product of2-furoic acid after a 2-h electrolysis at 1.55 V versus reversible hydrogen electrode in a 1.0-M KOH/50-mM furfural *** Pt-Co3O4electrode exhibited a small overpotential of 290 mV at 10 mA *** an anode and cathode in an electrolyzer system,the Pt-Co3O4electrocatalyst required only a small applied cell voltage of ～1.83 V to deliver 10 mA cm-2,compared with that of the pure water electrolyzer（OER‖HER,～1.99 V）.This study simultaneously realized the integrated production of energy-saving H2 fuel at the cathode and 2-furoic acid at the anode.
