Properties of proton resonances in $^{18}$Ne have been investigatedefficiently by utilizing a technique of proton resonant elastic scattering witha $^{17}$F radioactive ion (RI) beam and a thick proton target. A4.22~MeV/nucleon $^{17}$F RI beam was produced via a projectile-fragmentationreaction, and subsequently separated by a Radioactive Ion Beam Line in Lanzhou({\tt RIBLL}). Energy spectra of the recoiled protons were measured by two setsof $\Delta$E-E silicon telescope at center-of-mass scattering angles of$\theta_{c.m.}$$\approx$175${^\circ}$$\pm$5${^\circ}$,$\theta_{c.m.}$$\approx$152${^\circ}$$\pm$8${^\circ}$, respectively. Severalproton resonances in $^{18}$Ne were observed, and their resonant parametershave been determined by an $R$-matrix analysis of the differential crosssections in combination with the previous results. The resonant parameters arerelated to the reaction-rate calculation of the stellar$^{14}$O($\alpha$,$p$)$^{17}$F reaction, which was thought to be the breakoutreaction from the hot CNO cycles into the $rp$-process in x-ray bursters. Here,$J^\pi$=(3$^-$, 2$^-$) are tentatively assigned to the 6.15-MeV state which wasthought the key 1$^-$ state previously. In addition, a doublet structure at7.05 MeV are tentatively identified, and its contribution to the resonantreaction rate of $^{14}$O($\alpha$,$p$)$^{17}$F could be enhanced by at leastfactors of about 4$\sim$6 in comparison with the previous estimation involvingonly a singlet. The present calculated resonant rates are much larger thanthose previous values, and it may imply that this breakout reaction could playa crucial role under x-ray bursters conditions.
