Particle rebound models were developed using high temperature test results. ηpηp of 100 μm particle can reach up to 78% under a small amount of transferring steam. Qs equals to 0.25% is recognized as the optimum separation point. Particle trap B with annulus inlet is the optimal one considering ηpηp and ΔP. Effect of particle trap on the heat rate of thermal system is less than 0.15%.
