“…In recent years, many scholars have devoted to studying the influence of droplet size, droplet evaporation rate, steam flow characteristics and other factors on the desuperheater performance through experimental studies, numerical simulations and theoretical analyses [2][3][4][5][6]. Kouhikamali et al [4] improved the performance of the desuperheater by changing the initial size of the droplets and diameter of the pipe for two-dimensional simulations and concluded that the smaller the droplet diameter the faster the evaporation; Yumi Uruno et al [5] explored the effect of desuperheater structure on the secondary fragmentation of droplets and the distance required for complete evaporation of droplets in three-dimensional space.…”

An optimization scheme for installing static mixing element in desuperheater is numerical proposed to improve the poor desuperheater effect of traditional desuperheater in limited distance pipeline. By comparing and analyzing the working process and temperature reduction mechanism of the mixed fluid in the traditional and the new desuperheater, the results show that the mixing elements further facilitate the mixing of liquid droplets and superheated vapors, effectively improve the evaporation rate of the droplet, and effectively complete the temperature reduction process of high temperature and high pressure superheated steam. In the same distance of the pipe, the new desuperheater temperature reduction range is increased, and the temperature inhomogeneity coefficient is reduced by about 90%.
