Web1 dec. 2024 · Measurements of velocity and temperature in radial cross-section of low pressure water–steam injector are included in the study by Narabayashi et al. [12]. In continuation of this research, Ohmori et al. [13] present the results of endurance tests aimed at determination of the injector performance degradation during long-term operation. WebSteam lines are sized with attention to maximum velocities. Dry saturated steam should travel no faster than 40 m/s. Wet steam should travel somewhat slower (15 to 20 m/s) as …
