Desuperheater is a passive device to control the temperature of steam in various plants. However, in spite of its simple structure, the accurate prediction of a desuperheater is very difficult because there are many designed factors for the design of a desuperheater. In this study, the theory of heat transfer phenomena in a desuperheater was developed and the various design factors are evaluated. As a results, we confirmed that the droplet size of 30 - 200㎛ is best effective for the performance of a desuperheater.
