Effect of continuously flowing liquid Li limiter on particle and heat fluxes during H-mode discharges in EAST

•Particle and heat fluxes were successfully controlled by using continuously flowing liquid Li (FLiLi) limiter in the H mode discharges with high plasma heating power in EAST.•By using flowing liquid Li limiter, the fuel recycling could effectively reduce by ∼ 50% and Zeff could decrease from 2.3 to 1.6.•The decreased recycling and impurity radiation led to the achievement of high energy confinement plasma with the average stored energy increased up to ∼ 290 kJ.•Due to Li vapor shielding effect, ∼40% plasma heat flux was dissipated before arrived at the Li limiter.
